Home » Product » UVGI For HVAC

UVGI is a proven method for removing volatile organic compounds(VOCs) and for killing or deactivating bacteria, viruses, mould spores and other pathogenic microorganisms that may be present in room air.

Application Areas


UltraCoil & UltraDuct systems destroy high levels of airborne and surface bio contaminants. Infections Aquired in Hospitals (HAI) can be a significant cost for the healthcare industry and is considered a preventable injury. Ultra IAQ systems are the ideal tool to help reduce nosocominal infections.

Pharmaceutical, Food Processing And Produce

Air quality and the risk of surface contamination play a vital role in pharma clean rooms, and in the production & packaging of food products. UV Sterilization of both air and/or surface of product or packaging by UltraHVAC UV systems can dramatically reduce possibility of contamination.
In fruit/vegetable markets it can extend the life of the produce by destroying the off gassing (i.e ethylene) which cause faster aging.

Commercial Spaces, IT Parks And Schools

A WHO report suggested up to 30% of new and remodeled buildings worldwide may be subject to complaints related to poor indoor air quality, the leading cause of “Sick Building Syndrome.” According to the EPA, poor indoor air quality can directly affect the health of students, staff, employees, which in turn affect attendance and performance. Using UltraHVAC UV systems significantly improves air quality resulting in lower absenteeism and higher efficiency.

Benefits of UltraHVAC Systems

Better Indoor Air Quality(IAQ)
Greatly improves Indoor Air Quality (IAQ)and cures “Sick Building Syndrome” by destroying harmful airborne contaminants such as bacteria, viruses, mould and fungi

Eliminates odors
Reduces or eliminates unpleasant odors which may result from outside air or re-circulated air within the building

Greater savings
This helps to maintain a clean evaporator coil, thus saving time and resources on coil cleaning. Using MERV filters in conjunction with in-duct UV systems can reduce the need of HEPA


How Do UV-C Air and Surface Disinfection Models Work?

UV-C Air and Surface Disinfection models contain one or more germicidal ultraviolet lamps that produce ultraviolet wavelengths lethal to microorganisms. As the air passes through the UV-C purification device or the surface is exposed to germicidal UV light, the genetic material of microorganisms is deactivated, preventing them from reproducing and rendering them harmless.

What are applications for ultraviolet air disinfection?

Ultraviolet air duct disinfection fixtures can be used in two types of applications in HVAC equipment: treatment of the airstream or treatment of the surfaces within the air-handler. Coil Sterilization – to prevent mold and bacteria from building up on or around the coil and Air Sterilization – to kill microbes in the air.

What is the purpose of HVAC?

The main purpose of a Heating, Ventilation and Air-Conditioning (HVAC) system is to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort.

How often should you clean your HVAC system?

To maintain acceptable indoor air quality (IAQ), it is commonly recommended that mold, fungi, dust and other contaminants be cleaned out of the HVAC system at regular intervals.

Though there is no official recommendation by EPA in their Indoor Air Quality report on how often you should clean your HVAC system, you should definitely get ducts cleaned if you see mold growing inside them, or if the ducts have become infested with insects or rodents. As a rule of thumb, the National Air Duct Cleaners Association (NADCA) suggests cleaning your ducts every three to five years.

Do HVAC UV lights really work?

Yes, they are very effective if they are designed, installed & used properly. Ultraviolet (UV) lights for HVAC systems are commonly known as ultraviolet germicidal irradiation (UVGI) systems. They target a very specific type of air contaminant, namely microorganisms such as bacteria, viruses, and mold spores. The light affects only living microorganisms, meaning these systems can’t control dust, pollen, or other particles that aren’t alive.

How much does it cost to install a UV light in HVAC?

The cost would depend on the size of the HVAC & what is the target application being looked at, whether Coil Sterilization or Air Sterilization or both. Check with our application specialist.

What are the limitations to the use of germicidal ultraviolet for air and surface disinfection?

Germicidal ultraviolet does not penetrate through normal materials. Therefore, any surface or item that needs to be exposed to germicidal ultraviolet should have a direct uninterrupted path to the rays of the germicidal ultraviolet lamp.

Germicidal Ultraviolet rays cause harmful irritation to skin and eyes. Always wear protective clothing, gloves and eye shield (goggles, glasses, etc.) when working with direct ultraviolet radiation.
