Why Use UVGI?
Ultraviolet germicidal irradiation, or UVGI, is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms. UVGI fixtures produce UV-C energy, which has shorter wavelengths than more penetrating UV-A and UV-B rays and pose less risk to human health. Public health concerns such as multi- and extensive drug-resistant tuberculosis, bioterrorism, pandemic influenza, and severe acute respiratory syndrome have intensified efforts to prevent transmission of infections that are completely or partially airborne using environmental controls. One such control, ultraviolet germicidal irradiation (UVGI), has received renewed interest after decades of underutilization and neglect.
UVGI system for HVAC is here to help you get rid of all the poor-quality air problems. In one go, it will help you get rid of all the airborne microbes and leaves the air sparkle clean. There is no huge installation and maintenance with UVGI.
Problem: Indoor Air Quality & Sick Building Syndrome ( SBS )
- Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases such as volatile organic compounds, particulates, microbial contaminants (mould, bacteria), that can induce adverse health conditions there by leading to Sick Building Syndrome (SBS).
- Sick Building Syndrome is a medical condition where people in a building suffer from symptoms of illness or feel unwell for no apparent reason. The symptoms tend to increase in severity with the time people spend in the building and improve over time or even disappear when people are away from the building. The main identifying observation is an increased incidence of complaints of symptoms such as headache, eye, nose, and throat irritation, fatigue, and dizziness and nausea. These symptoms appear to be linked to time spent in a building, and mainly attributed indoor air quality of the building.
- HVAC Systems are typically inaccessible and a reservoir of mould, bacteria and slime that can circulate throughout any dwelling. These contaminants can cause allergies, asthma, cold, flu and sinus infections.

How does UVGI System Work for Air Purification?
UVGI can be used not only to disinfect surfaces but also for air. To do this, UV lamps are installed in the HVAC system in the main air stream or at the HVAC coils, after primary filtration.
How it works:- A UV light is installed in the ductwork
- The light kills viruses, bacteria, and fungi by damaging their DNA/RNA
- Air that receives a sufficient dose of UV radiation is disinfected Systems designed specifically for coil defouling are not eligible.
UVGI is one of the most preferred and non-intrusive ways to do air purification. UVGI system for HVA uses UV light in an inventive way. It’s smooth and hassle-free. High-risk zones like hospitals, schools, and corporate offices can be disinfected properly with the UVGI system.
UVGI In-duct & UVGI On-coil
We manufacture UVGI systems for HVAC Air Ducts that cease the circulation of allergens, airborne contaminants, and pathogens effectively, making air safe and clean to breathe. Our HVAC solutions are designed after evaluating the amount of irradiation required depending on the air flow and traffic.
Our UV air disinfection system provides complete air sterilization and disinfection providing optimal air quality. UV-C is installed at a particular angle and the reflectors ensure that the light gets concentrated at a particular point improving overall air disinfection results. Our UVGI system stands idyllic for both small and medium areas as it is highly compact. When installing the UV air purifiers in AHU units, we take complete care that no compromise is made of unit’s performance in terms of cooling and the weight also stays considerate.
Usage of UV Lights for Air Disinfection
Not many of us know this but indoor air could be 7% more infected than outdoor air. But, people often consider it clean as they can’t see the minute microorganism present in it. Poor-quality indoor air is a matter of concern as we spend most of the time inside the walls, not outside the wall.
As per a recent study, people spend 87% of their time indoors, inhaling that not-so-fresh air. Whether you work, sleep, party, or exercise, you are inside four walls most of the time. Hence, it’s imperative that the indoor air around you is disinfected properly.
No chemical, no emission of harmful gases, and impressive energy saving, this is what you’re going to experience while you use UV light for air disinfection. While you enjoy all these perks, no compromise on quality is made. UV light has a 99% inactivation rate.
UV Light - The Perfect Air Disinfected
Indoor air disinfection is crucial if one wants to maintain pink health. The most effective and chemical-free means to make this happen is using a UV light as an air disinfectant.
UV or UltraViolet rays are what we receive from the sun as a part of sunlight. UV rays have the ability to disinfect a surface, water, and air in a chemical-free and non-destructive way.
The three types of UV rays are UV A, UV B, and UV C. Out of all these UV C has the highest air disinfected qualities. It holds the potential to kill a wide range of microorganisms such as vegetative and spore-forming pathogens. When these microorganisms are exposed to UV C light, their genes are destroyed or scrambled which makes them inactive. This way it eliminates many trouble-causing elements from the air surrounding you and makes it fresh.
Benefits of Using Germicidal Irradiation (UVGI) for HVAC
Improved Indoor Air Quality Germicidal UV can help disinfect at the source of germs, which is typically coils or drain pans. It can greatly reduce the threat of pathogens entering the building through the HVAC system.
Improves Efficiency A lot of pathogens will impede the air-flow leading to the unit consuming higher energy to provide the required temperature. As a result, additional energy is wasted. UVGI keeps all kinds of pathogens away from air ducts.
Energy Savings (Coil Type UVGI) Germicidal UV fixtures not only clean your system, they improve the heat exchange efficiency. That means your energy costs are going down.
Reduced Maintenance Germicidal UV acts as a source of constant maintenance for your HVAC system. Instead of having to constantly pressure wash or clean equipment, germicidal UV constantly cleans disinfects, leading to less mold build-up.
No Harsh Chemicals You can stop using those bleach tablets in your drain pans. Germicidal UV can replace or reduce the use of harsh chemicals. Plus, you can enter a room immediately once the product is ON. No need to wait for harsh chemicals to dissipate.
The Benefits of UVGI System
Once you decide to use UVGI System for air disinfection, understand that you’re eligible to avail below-mentioned benefits:- This technology is affordable as compared to other air disinfection technologies.
- This lower cost is possible because of many ways such as low energy consumption, very less maintenance, and high product life.
- It’s an environmentally-friendly option as no chemicals are used to kill the germs.
- The technology is highly portable. We have heavy to lightweight UV lamps that are useful for any ecosystem. Whether you want to disinfect your home or your office, it’s possible.
- UV C light can kill up to 99% of germs. So, it’s basically guaranteed air quality.
