Does UV Light Kill Covid in Water, Surfaces, and in Air?

Ultraviolet (UV) UV light emitted specifically in the UVC range is proven to be highly effective at killing many germs including tough bacteria and viruses. UVC radiation emitted at specifically 254 nm wavelengths is the most effective to inactivate viruses and bacteria by penetrating the cells of these microorganisms and rendering them unable to replicate. UVC wavelengths emitted in the range of 207 - 222 nm is referred to as far UVC light, which is also very effective at sterilization while not quite as harmful to human skin and eyes. 

UV Sterilization in Water

UVC germicidal lamps are used in many water sterilization applications such as wastewater treatment plants, pool and spa and many other water disinfection applications. Germicidal UV lamps have been proven to eliminate many harmful bacteria that even chlorine does not kill, like Cryptosporidium and Giardia. UV light is also proven to kill harmful beta coronaviruses, like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).  The SARS-CoV-2 virus that causes COVID-19 is in the same beta coronavirus family as MERS and SARS and UV light is also effective at eliminating the SARS-CoV-2 virus, as shown in this recent study. 

UV Light Kills SARS CoV-2 Virus on Surfaces

UVC lamps are highly effective at eliminating harmful pathogens on surfaces and are in wide use in many applications such as hospitals, schools, and laboratories. Surfaces should be clean and indirect exposure of UV radiation for maximum efficacy, which is why many hospitals follow manual cleaning procedures with a roaming UVC robot. This is an effective practice to significantly increase the safety of patients in hospital rooms and staff. 

UVC Lamps Kill Covid in the Air

The SARS-CoV-2 virus that causes COVID-19 is known to spread the airborne particles which is one of the most common modes of transmission and infection. UVC air purification systems kill viruses and bacteria as they circulate through the air in your home or office, protecting people from airborne disease. UV lamps in HVAC and central AC units provide automatic 24/7 protection by killing viruses that pass through air handling units (AHUs) and protect your equipment by preventing the buildup of mold and fungi.

UVC germicidal lamps are highly effective at eliminating bacteria and viruses, including beta coronaviruses and the SARS-CoV-2 virus that causes COVID-19.

Do UV Lights in HVAC Systems Improve Air Quality?

Ultraviolet (UV) lamps designed to emit wavelengths in the short wave UVC range have germicidal properties which eliminate harmful bacteria and viruses.  UVC lamps designed to emit wavelengths specifically close to 254 nm for germicidal applications and 185 nm for ozone applications are most effective.  Germicidal lamps are proven to quickly eradicate even stubborn bacteria such as antibiotic resistant superbugs and inactivate viruses, including beta coronaviruses such as MERS, SARS, and SARS-CoV-2 which is the virus that causes COVID-19. 

By cleaning the air that passes through air handling units of HVAC systems, UV lights in HVAC systems help to improve indoor air quality and also prevent mold and fungi from building up on internal HVAC components. This is one of the biggest benefits of UV lights for HVAC systems, as heating coils are susceptible to contamination, a build-up of mold and fungi due to the moist environment. UV lamps directed at heating coils and in ducts prevent mold build up and contamination, thus improving HVAC performance and energy efficiency.

UV Lamps in HVAC for Residential, Commercial, and Industrial

UVC lamps have long been used in the medical field and in hospitals to protect patients and staff from lingering viruses and bacteria. Upper room ultraviolet germicidal irradiation (UVGI) is proven to help protect patients against tuberculosis and has been used for decades with guidance from the Centers for Disease Control and Prevention, CDC, an environmental control of tuberculosis bacteria with UV lamps in upper room UVGI for air sterilization. 

Several additional studies examine the effectiveness of UV lamps in HVAC systems for air sterilization and purification, such as the study by Dick Menzies, et al, published in the National Institutes of Health, which examined the effects of UV air purification lamps on work related illnesses and symptoms of employees. The study showed a clear correlation between improvements in health-related worker symptoms when UV lamps were used in HVAC systems to promote improved indoor air quality.

Are UVC Robots Effective in Killing the SARS CoV-2 Virus?

One full year into the COVID-19 pandemic and we are seeing the light at the end of the tunnel, with widespread vaccinations and people everywhere doing what they can to reduce the spread of infection. With several studies documenting the effectiveness of UVC germicidal lamps to kill the SARS-CoV-2 virus that causes COVID-19, businesses are taking notice and investing in UV disinfection systems to protect their staff and the public. In addition to typical UV light water, surface and air sterilization systems, UVC robots are in high demand. 

Many hospitals across the country have invested in UV light robots to provide an added layer of protection against spreading disease. In spite of the most meticulous manual cleaning regimen, hospital staff can be pushed to the limit and operating with limited personal protective equipment. A UVC robot can be programmed to enter a hospital room after a manual cleaning process, and effectively kill bacteria and viruses often time missed even with the most diligent attempt at disinfection. UVC robots aid weary hospital staff without being on the payroll or needing a break, they simply make their way back to the charging station when required and deliver powerful germ killing UVC light to eliminate viruses and bacteria.

UVC Robots Proven Effective

Several studies have now been conducted which verify the effectiveness of UVC germicidal lamps to kill the SARS-CoV-2 virus, which is a member of the beta coronavirus family similar to MERS and SARS.  Middle East respiratory syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) are in the same coronavirus family and have been known to be effectively eliminated by UVC radiation.  UVC light effectively inactivates these viruses as shown in a recent study by PURPLESUN which shows dosage and exposure time required to inactivate various types of coronaviruses as well as exposure time required to effectively kill drug-resistant bacteria.

Not only will UVC robots help hospitals to prevent the spread of COVID-19, they also continue to reduce risk of common health care associated infections (HAIs) from superbugs often found in hospitals. With UV light sterilization gaining in popularity, UVC robots are now seen outside of the medical field in places such as airports, train stations, shopping malls and public shelters.

Do UV Lamps Kill the SARS-CoV-2 Virus That Causes COVID-19?

Ultraviolet (UV) light is a type of electromagnetic radiation that has more energy than visible light but less energy than x-rays and gamma rays. UV light from the sun is replicated in UV lamps for things like tanning beds and disinfection applications. UV light is broken down into different spectrums mainly UVA, UVB and UVC light. 

UVC light is the wavelength with germicidal effectiveness and is mostly absorbed by the Earth’s ozone layer before it reaches the ground. UVC germicidal lamps are designed to emit wavelengths at the optimal nanometer to kill germs which is typically 254 nm or 185 nm for ozone lamps.  According to the study Upper-room ultraviolet air disinfection might help to reduce COVID-19 transmission in buildings: a feasibility study by the National Institutes of Health, several studies have demonstrated that the SARS-CoV-2 virus that causes COVID-19 is relatively easily inactivated by UVC disinfection lamps similar to other airborne coronaviruses.  Additionally, conclusions from this study state that Upper Room Ultraviolet Germicidal Irradiation (UVGI) with UV light at 254 nm has the potential to inhibit the transmission of COVID especially in confined places like hospital rooms or public places or anywhere that achieving a high ventilation rate is not practical.

UV Lamps in HVAC Systems Fight Spread of Disease

The use of ultraviolet (UV) light in disinfecting and sterilizing surfaces is gaining as part of the fight against the spread of the novel coronavirus and to control health acquired infections (HAIs) in hospitals. HAIs are a serious problem for hospitals, especially when stretched at capacity and short on staff.  Even prior to the COVID-19 pandemic, nearly 1 in 25 patients were estimated to contract an HAI from a hospital stay, some with dire consequences. Protecting patients and staff against HAIs including drug-resistant bacteria and serious viruses with effective hospital disinfection is top priority for hospitals and healthcare facilities. 

Nearly everything that is in a hospital room from all the surfaces to airborne particles, medical equipment and the clothing and hands of healthcare workers can serve as a reservoir and vector for transmitting opportunistic pathogens.  While contaminated surfaces and insufficient hand hygiene are the primary modes of transmission, water and air supply systems also provide a mode of transmitting harmful pathogens.

UVC HVAC Air Purification Systems

While maintaining regular cleaning and manual disinfection practices is crucial in hospitals, along with proper hand hygiene, germicidal UVC lamps in moving air applications are proven to disinfect and purify the air. Ultraviolet Devices, Inc, UVDI, offers HVAC air disinfection and purification systems with advanced UV technology. UV air disinfection eliminates viruses and bacteria with a kill rate up to 99% and UV air purification destroys volatile organic compounds (VOCs) and foul odors.

UV moving air applications include two basic systems for UVGI as a supplemental air cleaning measure:

Upper room air irradiation – UVGI lamps are wall mounted above an occupant’s level, usually 8 feet above the floor and irradiate the airflow in the room.  Upper room UVGI has been used in tuberculosis wards to inactivate TB and is also effective in patient rooms, emergency rooms, waiting rooms, hallways and anywhere patients could potentially spread airborne germs.

HVAC Duct Irradiation – UVC germicidal lamps placed inside HVAC and air handler ducts disinfect recirculated or outside air. UVC lamps in air handling units effectively eliminate microscopic organisms that are too small to filter yet are easily disinfected with UV light.

LightSources offers high-quality UVC lamps found in UV sterilization systems for hospitals including air disinfection UVGI mounted, HVAC and portable systems  Our UVC robot lamps are helping hospitals to improve patient and staff safety and prevent the spread of disease with effective surface sterilization.

Does Ultraviolet Radiation Kill the COVD-19 Virus?

Ultraviolet radiation is proven to kill viruses and bacteria and there have been many questions about the efficacy of UV light killing the novel coronavirus.  The current pandemic with the outbreak of COVID-19 is caused by the coronavirus SARS-CoV-2, and people want to know if they can purchase UV lights for their home to help protect themselves and their family with effective sterilization.  Hospitals have been using UVC lamps in surface sterilization devices and UVC robots to further sterilize patient rooms and surfaces.

The U.S. Food and Drug Administration, FDA, answers your questions about UV Lights and Lamps: Ultraviolet-C Radiation, Disinfection, and Coronavirus. 

UVC Radiation and the SARS-CoV-2 Coronavirus

UVC radiation is proven to destroy the SARS-Coronavirus, which is a different coronavirus than what causes COVID-19.  SARS-CoV-2 is the virus that causes COVID-19 and given the newness of the virus there are many ongoing research studies to verify accurate dosage of UVC exposure including exposure duration and distance, which is key to effective sterilization with germicidal UVC lamps. 

Studies like this one by Boston University are showing promise with results that show a 99% reduction of the SARS-CoV-2 virus when UVC radiation is dosed at the right level.  This study shows that UV light will deactivate the coronavirus in 6 seconds when dosed at 5 mJ/cm2.  Another study conducted by Biological Consulting Services in Feb.2020, shows effective elimination of SARS-CoV-2 virus and many other stubborn microorganisms in UVGI irradiation with 99.99% effectiveness with 15 minutes of exposure.  With surface sterilization at direct exposure and UVGI air irradiation, hospitals can significantly improve the health of patients and prevent the spread of disease. 

Hospitals using UVC light to eliminate the spread of disease and consumers wishing to purchase UVC lamps to sterilize surfaces at home must remember that direct exposure is key.  UVC radiation will only kill microorganisms that are directly exposed to the UVC radiation emissions.  Inactivation of the virus on surfaces will not be as effective if blocked by shadows, dust, soil or organic compounds which absorb the UV light and reduce the efficacy of sterilization on the surface.

UV Light Prevents Grease Build Up in Kitchen Exhaust

Kitchen hood exhaust systems in commercial kitchens serve a very important purpose, to pull grease particles up and away through mechanical filters.  Kitchen exhaust systems vent excess heat above kitchen stoves and extract grease particles, leaving smaller particulates that may linger in the hood exhaust system.  These kitchen exhaust systems can encounter grease build-up in the vents if they are not cleaned regularly or treated with UV light sterilization solutions. 

How Does UV Light Help Kitchen Hood Exhausts?

Ultraviolet (UV) light emits UV radiation, electromagnetic energy, and is harnessed in UV germicidal lamps used in a vast range of applications.  UV light is used to purify the air, disinfect water and sterilize surfaces.  Utilizing UV light in kitchen hood exhaust systems provides many benefits beyond sterilization.  Kitchen hood UV exhaust systems can actually prevent grease build-up in the exhaust duct work.  

UVC lamps break down grease through photolysis and ozonolysis. UV light causes a photochemical reaction, breaking down the molecular bond while ozonolysis oxidizes the grease molecules. By breaking down the grease particles, they are converted into particles that are much easier to clean and do not build-up grease in the kitchen hood.  

This brings many benefits to restaurant owners by mitigating the risk of a grease fire, which can often occur with grease build-up in the exhaust hood.  UV kitchen exhaust systems also help kitchens to meet stringent health department code regulations by helping to keep the kitchen cleaner.  This provides a better work environment for employees and helps to maintain health standards for patrons. 

UV Lamps are Key to Successful UV Sterilization Systems

Using the right UV lamps for your UV kitchen exhaust sterilization system is key to successful prevention of grease build-up and sterilization.  UV germicidal lamps designed to emit 254 nanometer (nm) are effective in sterilizing air and surfaces.  Ozone producing lamps emit UV energy at 185 nm and are commonly used in air and water disinfection applications, deodorizing the air and reaching places that standard UV radiation cannot reach. 

When searching for the best UV lamps for your sterilization application, contact an experienced UV lamp manufacturer like LightSources. 

LightSources leads the industry in UVC germicidal lamp production, with a wide range of low-pressure, amalgam and many other lamp types designed with proprietary technology.  We provide high-quality UVC lamps proven to outlast and outperform comparable lamps of the same size.  Contact us to learn more and for custom lamp requirements for your UV germicidal application.

Solutions for Challenges Facing Hospital Disinfection

Disinfection practices in hospitals have always been of great concern with the number of patients carrying viruses and bacteria, and the potential exposure to patients with compromised immune systems.  Hospital acquired infections are infections that occur within the first 48 hour of being admitted to the hospital, within the first three days following a hospital discharge or within the first 30 days after an operation.  The Center for Disease Control, CDC, estimates that approximately one in every 25 of hospital patients in the U.S. contracts a hospital acquired infection (HAI).  Many HAIs are resistant to treatment with antibiotics and can lead to sepsis or even death. 

HAIs and disinfecting patient rooms are of great concern for hospital staff for many reasons:

• Patients being discharged may have had a contagious, serious viral or bacterial infection

• Incoming patients are already ill and may have a compromised immune system

• Hospital staff move from room to room and have a high potential to carry pathogens from one patient room to the next

Hospital Cleaning Practices

Hospitals take their cleaning, sanitizing and disinfecting practices very seriously. Even with the most careful cleaning procedures, human error can contribute to less than sanitary conditions. Disinfecting patient rooms thoroughly can be challenging due to many factors such as:

• Using contaminated cloths which spread disease

• Using diluted disinfectant cleaning solutions

• Insufficient contact time of cleaners with surfaces

• Human error, cleaning staff can miss an area when manually cleaning

Adding UV Light Disinfection

Adding UV light disinfection to standard hospital cleaning practices has been proven to greatly increase sterilization success. UV light in shortwave UVC radiation quickly eradicates many viruses and bacteria with high efficacy and can reach into places that manual cleaning cannot access.  

UV germicidal lamp manufacturers design and engineer UVC lamps to emit the most powerful wavelength of UVC radiation at 254 nanometer.  UVC radiation penetrates the cells of viruses and bacteria, rendering them unable to replicate and leaving them harmless. High-quality UVC germicidal lamps are the key to effective UV sterilization.

LightSources is a leading global supplier of UVC germicidal lamps, with a wide range of UV germicidal lamp types.  We offer standard low-pressure mercury lamps, amalgam lamps with proprietary technology, Germipak, U-lamps and custom engineered solutions.  Contact us to learn more about our high-performance UV germicidal lamps.

How UV Light Keeps Kitchens Clean

Ultraviolet (UV) is a powerful disinfectant used in many applications to sterilize water, air and surfaces.  High intensity UV lamps eliminate harmful pathogens and break down volatile organic compounds (VOCs).  UV radiation in the wavelength of UVC ultraviolet light is highly effective at eradicating bacteria, viruses, mold, mildew and can even break down grease buildup.  UVC germicidal lamps are being used in many residential, industrial and commercial applications such as restaurants and kitchens. 

UVC germicidal lamps can help to keep restaurants and kitchens clean in many areas such as:

• UV air purification for healthy air in eating areas

• UV surface sterilization over food preparation areas

• UV lamps prevent mold and mildew in walk-in freezers

• UV food irradiation to prevent foodborne illnesses

• UV lamps in kitchen exhaust to prevent grease buildup

Commercial kitchens utilizing UV germicidal lamps in kitchen hood exhaust systems experience cleaner kitchen exhaust without grease buildup which also reduces the risk of kitchen grease fires.  Kitchen hood exhausts with UVC lamps provide low-maintenance, self-cleaning technology to help restaurant owners provide a cleaner and safer kitchen and to meet stringent health department code regulations. 

How UV Lamps Eliminate Grease Buildup

UV lamps eliminate grease buildup through a chemical reaction called photolysis and ozonolysis.  Photolysis, or photodissociation, occurs when photons break down oxygen molecules to oxygen atoms, which combine with remaining oxygen molecules to form ozone. Ozone causes a reaction with the organic compounds found in the grease through a process called ozonolysis. Ozonolysis forms byproducts which are easier to clean and reduces grease deposits and buildup in kitchen hood exhaust and duct systems.

Does UV Light Kill Superbugs Like MRSA?

Ultraviolet (UV) light is a powerful form of electromagnetic radiation that occurs naturally from the sun and is replicated in UV lamps.  UV light is emitted at wavelengths on the electromagnetic spectrum that fall between X-rays and visible light in the range of 10 to 400 nanometer (nm).  UV light is not visible to the human eye as it has a higher frequency and shorter wavelengths that images our brain can perceive. 

UV light is further broken down into UVA, UVB and UVC, with UVC wavelengths being the most powerful for germ killing action.  UVC light has been recognized for centuries as having powerful germicidal properties.  UVC light emitted at precisely 254 nm is known to quickly eradicate viruses and bacteria by penetrating the cells of microorganisms and altering the DNA to prevent replication.  

A cell that cannot replicate poses no threat and is no longer a harmful pathogen.  UVC germicidal lamps are known to effectively eliminate tough viruses, bacteria, volatile organic compounds (VOCs), even mold, mildew and other harmful microorganisms. UV light is also proven to effectively eliminate some of the toughest superbugs out there like vancomycin-resistant enterococci (VRE), C. difficile, Acinetobacter and Methicillin-resistant Staphylococcus aureus (MRSA).

Hospitals are using UV light in many types of UV germicidal systems such as in HVAC units for cleaner air and in UVC robots to clean hospital rooms.  UVC radiation is proven effective on superbugs when exposed for the right amount of time, some germs are eradicated in seconds while others require a few minutes of exposure.

How Restaurant Owners Benefit from UV Sterilization

Ultraviolet (UV) light has been proven for centuries to eliminate harmful bacteria and viruses and is widely used in many environments and applications for disinfection purposes. UV light sterilization provides overwhelming benefits to many industries, especially restaurants and food preparation facilities. 

Ultraviolet sterilization can be delivered in many ways to protect nearly every single area of a restaurant including food prep countertops, kitchen areas, walk-in freezers, kitchen exhaust hoods, and dining areas. In addition to providing clean surfaces, UV light is used directly on food items in food irradiation which is safe and improves food quality.  UV air purification systems protect patrons from airborne disease and water sterilization ensures clean water free from harmful microorganisms.

Food Irradiation

UV exposure directly to food items is called food irradiation which is completely safe, helps to prevent foodborne illnesses and prolongs food shelf life.  Food irradiation provides many benefits to restaurants such as:

Reduces the risk of foodborne illnesses such as Salmonella, listeria, E. coli and other harmful microorganisms

Extends the shelf life of many food items

Reduces food spoilage

Lowers the risk of importing or exporting pesky insects hidden inside food products

Lessens the need for additives such as antioxidants and preservatives

Lessens the need for pesticides

Reduces early sprouting in potatoes, onions, spices and herbs

UV Surface Sterilization in Restaurants 

UV light sterilization systems provide clean surfaces free from harmful germs, bacteria and viruses simply by emitting UVC light in the right wavelength over countertops and food preparation areas. UV lights can be installed over counters, stoves, food buffets, delis and even walk-in freezers and kitchen hood exhausts.

UV sterilization lamps installed in walk-in freezers help to prevent mold and mildew which can easily occur in cool, damp places. UV lights in kitchen hood exhausts actually help to prevent grease buildup by altering the molecular structure of the grease into components which are more easily cleaned and removed, thus helping to prevent fires.

UV Air Purification Systems in Restaurants

UVC Robots are Disinfecting Hospitals with Germicidal Lamps

Current events have drawn attention to the need for greater disinfection and sterilization systems and raised awareness to the benefits of automatic sterilization such as from UVC robots. Ultraviolet (UV) light disinfectant robots are increasing in use in busy, populated areas such as airports, congregation halls and especially in hospitals. UVC robots can eliminate 99.99% of viruses and bacteria in a hospital room in less time than a human can clean the room and with greater effectiveness.  

The UVC radiation emitted from UVC germicidal lamps reaches into corners and crevices, from the ceiling to the baseboards and everything in between without missing a spot that can occur with human cleaning and the possibility of human error. Hospital employees can set the robot up in a patient room and leave the room for about 15 minutes while the robot roams around disinfecting every surface. The employee can come back and simply flip over mattresses and turnover call buttons and leave the room again to run a second cycle.

Hospital acquired infections (HAIs) were already a serious problem before the pandemic of 2020, with nearly 1 in 25 patients in a hospital acquiring an infection due to their stay, according to the Centers for Disease Control and Prevention.  Deploying UVC robots in hospitals provides significant protection to patients against contracting superbugs left in the room from previous patients.

What Viruses Does UV Light Kill?

Many harmful, infectious microorganisms are transmitted by various means such as droplets on surfaces, in the air and through human touch. Tuberculosis, measles, and influenza are all harmful, infectious organisms known to be transmitted between infected people to susceptible persons through shared airspace. Transmission may occur in areas of congregation within the room and also in hallways and through HVAC ductwork.

UV light emitted in the UVC range is known to kill tuberculosis, measles and influenza, and has been established in various medical journals for decades.

Ultraviolet Light Effectively Kills Many Microorganisms

Ultraviolet (UV) light emitted in the UVC wavelength predominately at 253.7 nm is proven to eliminate the threat from harmful viruses and bacteria by instantly altering cell DNA. UV light penetrates the DNA of these cells rendering them unable to replicate or cause infection, thus killing the threat from the virus.  

UV light is proven to have a germicidal effect on the following viruses: 

• Measles

• Smallpox

• influenza virus

• SARS (SAR-Cov)

• MERS (MERS-Cov)

Microorganisms and bacteria which respond to UV light sterilization:

• Vegetative bacteria

• Staphylococcus aureus including various species:

  • Escherichia coli (E. Coli)

  • Pseudomonas aeruginosa

  • Serratia marcescens

  • Streptococcus pyogenes

Viruses and vegetative bacteria are in general most susceptible to ultraviolet sterilization, followed by additional microorganism groups such as:

• Bacterial spores

• Mycobacteria

• Fungal spores

UVC germicidal lamps are effective in water, surface, and air sterilization, improving the health and wellness of people in many environments. UVC lamps in air handling units and HVAC systems eliminate the threat of airborne viruses with powerful UVC radiation sterilizing the air that flows through your ventilation system.

How UV Light Sterilization Helps Keep Hospitals Safe

Current events happening around the world are raising awareness of the critical care that hospitals provide, the necessity for sterile equipment and the responsibility that hospital administrators feel to provide safe healthcare to their communities.  The Centers for Disease Control and Prevention (CDC) estimates that Healthcare Acquired Infections affect 31 people every day in the United States. 

UV Light Sterilization in Air Ventilation Systems

Diseases such as tuberculosis, measles and the influenza virus are all known to be spread through the air between infected people and others in a shared space.  Patients who enter a room after a person known to have a transmittable disease are at risk for acquiring infections and worsening their health condition. UV air purification systems are known to eliminate these harmful diseases and many others to protect vulnerable people in hospitals.

UVC Germicidal Lamps Used in Healthcare

UVC germicidal lamps have long been used to sterilize operating equipment and for use in overhead lamps in patient and operating rooms. Low-pressure mercury vapor lamps which emit wavelengths at an effective 253.7 nanometer (nm) are popular in surface and air sterilization applications.  UV sterilization lamps improve indoor air quality (IAQ) in healthcare facilities, hospitals and many public places to protect against the spread of many harmful pathogens. 

UVC sterilization lamps are proven to be highly effective, removing up to 99% of CFU counts in just one month, as reported by Avinash Kulkarni (PhD), Aeropure UV Systems Pvt Ltd, INDIA.  UVC germicidal lamps used in conjunction with an air particulate filter system provide an incremental benefit to improve the air quality and drastically reduce the risk of infection.

UV sterilization systems also help a restaurant maintain a cleaner facility to comply with food safety regulations and health department inspections.  UV air purification systems also help any facility to maintain a healthier eating area by disinfecting the air in public spaces.  UV air sterilization systems are proven to remove harmful airborne pathogens to reduce the risk of contracting an airborne illness. 

Food Irradiation with UV Germicidal Lamps

Food irradiation is the term used to describe UV germicidal lamps used to preserve food with ultraviolet radiation.  Food irradiation is proven to prevent infection from bacteria and preserve food without any adverse health risks.  UV light is proven to prevent foodborne illnesses such as E. Coli and Salmonella and also preserves food by preventing early sprouting of potatoes or culmination of foodborne insects. 

Restaurants can protect their food by using UV lights above food preparation areas and countertops as well as over food buffets or serving areas. UV radiation emitted at the optimal wavelength, 254 nanometer (nm), alters the DNA of harmful pathogens including bacteria and viruses, and is effective in food irradiation and also on surface sterilization applications. 

UV Air Sterilization

UV lamps are incorporated in HVAC systems to prevent the growth of mold and mildew on cooling coils and may also be aimed to reduce airborne pathogens circulating through the ventilation system.  UV air purification systems may also incorporate ozone lamps to remove foul odor from the air.  UV kitchen exhaust systems over commercial kitchen hoods can even prevent the build up of grease by oxidizing oil fumes into carbon dioxide and water molecules to be removed by kitchen exhaust. 

UV sterilization systems in commercial kitchens provide many benefits such as:  

• Eliminates a fire hazard when used in kitchen exhaust systems by removing the threat of grease build up in the pipeline

UV disinfection of food products is called food irradiation and helps to prevent early spoilage and harmful bacteria and viruses from developing. Food irradiation is proven to eliminate Salmonella, E. Coli and other harmful microorganisms.  UV sterilization lamps used on food products is regulated by the FDA as an approved disinfection method for use on many food items including:

• Fruits and vegetables 

• Meats and raw poultry

• Many dairy products

• Beverages 

UV Lamps Beneficial in Many Areas of Restaurants

In addition to improving the safety of food items, UV germicidal lamps can also be used to disinfect and sterilize surfaces such as all contact surfaces in restaurants like food preparation countertops and serving stations. UV lamps can be used in refrigerators and walk-in freezers to prevent mold and mildew which can occur in damp spaces. 

You might see UV lights over a food buffet, a deli, or over fruits and vegetables to prevent foodborne illnesses. UV disinfection in restaurants adds a layer of protection over regular cleaning methods and helps to keep patrons and staff safe from foodborne illnesses and contaminated surfaces. 

UV disinfection of surfaces in restaurants provides many benefits such as:

Indoor Air Protection with UV Sterilization Lamps

Indoor air quality (IAQ) is an important consideration related to the comfort and health of building occupants.  IAQ is affected by the quality of air in and around buildings with airborne contaminants existing both inside and outside.  Controlling pollutants inside will help to reduce risk and improve the quality of indoor air for greater health and well-being. 

Airborne contaminants that exist both inside and outside of buildings include:

• Indoor pollutants:

• Wood burning stoves

• Tobacco smoke

• Cooking 

• Ozone and chemical emissions from cleaning solvents, electronic equipment and human metabolic byproducts

• Outdoor pollutants:

  • Agricultural and farming

  • Vehicle exhaust

  • Waste management facilities

  • Chemical storage areas

  • Processing equipment emissions

  • Combustion byproducts during manufacturing

UV Air Purifier in HVAC Systems

HVAC systems can be a great source of air pollution if dirt accumulates in the ventilation system.   Dirt combined with moisture and poor management of condensation can create serious air quality problems due to biological growth.  This typically occurs due to problems with the cooling coil condensation, humidifiers and other sources of moisture, poor maintenance of filters and inadequate particle filtration. 

Air contaminants may be either biological, gaseous or particulate. Methods of improving air quality include eliminating the source of emissions, capturing emissions at the source with exhaust, dilution, increased ventilation, filtration and air sterilization. Of these methods, the only one that actually eliminates biological contaminants is air sterilization.  HEPA filters effectively filter particles as small as .3 microns, although they are ineffective against volatile organic compounds (VOCs) present on a molecular scale. 

UV air sterilization is proven to eliminate VOCs and microorganisms such as bacteria, viruses, mold and fungal spores and many other air contaminants. In-duct UV air purification systems installed near the cooling coils of HVAC units prevent microbial growth on cooling coils, thus preventing the spread of these contaminants throughout the home, office or building.
