Adding UVGI System In HVAC System: Meaning, Benefits, Tips, And More
Businesses in India who got an HVAC system installed often think their job ends with heating, cooling, and keeping temperatures comfortable. While that’s certainly true, modern buildings nowadays require more than that. UVGI systems are being added to HVAC while prioritising:
- Indoor air quality
- Occupant health
- Energy efficiency
- Contamination control
But what exactly is a UVGI system? Why are offices, hospitals, commercial facilities, and even educational institutions exploring this technology as part of their air quality improvement strategy? How does it work inside the HVAC system? And most importantly, what tips to consider when adding it?
In this blog, Kelvin will answer important questions that businesses have regarding adding a UVGI system to HVAC.
Let’s start.
What Does UVGI System Actually Mean?
Ultraviolet Germicidal Irradiation (UVGI) is a technology that utilises ultraviolet-C (UV-C) light to aid the control of microorganisms (like bacteria, viruses, and mould) that may be present in HVAC systems and your indoor environment. No need to replace conventional air filtration techniques. UVGI works as an additional layer of protection.
The technology is typically placed in air handling systems, ductwork, or near HVAC coils, where conditions are more favourable for the proliferation of microorganisms. It is used to enhance indoor air quality, promote cleaner HVAC operation, and provide a healthier indoor environment for building users.
How Exactly Does a UVGI System Work? A
UVGI system can appear very technical at a cursory glance. But how does it actually work? Well, that’s relatively simple. It leverages specially designed UV-C lamps, which generate germicidal UV light that can disrupt the activity of microorganisms.
UV-C lamps are installed inside the HVAC system
The first step is the installation of the UV-C lamps in appropriate areas of the HVAC system. The typical locations are air handling units, cooling coils, drain pans, and duct sections.
Air passes through the irradiation zone
Indoor air is naturally drawn through the sections where the UV-C is being emitted as the HVAC system begins operating. This enables the moving air stream to be subjected to ultraviolet energy.
Microorganisms are neutralised
The UV-C light disrupts the genetic material of bacteria, viruses, mould spores and other microorganisms that it comes in contact with. This inhibits their ability to reproduce and spread.
Coil surfaces remain cleaner
UVGI systems are often employed to prevent biological growth on cooling coils. Keeping them clean improves air flow and performance of HVAC systems.
Improved indoor air quality
The UVGI technology reduces microbial contamination in the HVAC system which leads to cleaner air moving through the building.

What Are Benefits Of Adding UVGI System To HVAC Setup?
We hope you now understand what a UVGI system is and exactly how it functions. Let’s explore why countless commercial structures are turning to this technology. UVGI can complement HVAC systems for several other reasons while maintaining the comfort levels indoors:
Improved indoor air quality
A major benefit of UVGI technology is that it can improve indoor air quality. It keeps microorganisms under control in the HVAC system which in turn helps to create a healthier environment for the indoor occupants.
Reduced microbial growth
Mould, bacteria, and other biological contaminants can grow in areas like cooling coils and drain pans. UVGI systems are effective at reducing the accumulation of microorganisms in these critical HVAC components.
Better HVAC system efficiency
When biological growth builds up on HVAC components, the efficiency of airflow and heat transfer can suffer. But thanks to UVGI technology, they can remain cleaner. And do you know what cleaner coils do? They ensure your unit runs efficiently and maintain consistent performance.
Lower maintenance requirements
Too much microbial growth means frequent need for cleaning and upkeep. UVGI technology keeps certain HVAC system components cleaner. Potentially reducing maintenance efforts in the long run.
Enhanced occupant comfort
The quality of the indoor air directly impacts the experience of the occupant. Better air circulation within the building can help to improve the comfort of staff, visitors, customers, students, and patients.
Supports health and hygiene objectives
Commercial facilities, hospitals, educational institutions, and public buildings all prioritise cleanliness and indoor environmental quality. UVGI systems complement broader air quality and hygiene measures in these areas.
Longterm value for commercial buildings
UVGI indeed requires upfront investment. But hey, take a look at the bigger picture and you’ll realise it’s a long-term enhancement to your HVAC infrastructure. Especially if you’re someone who prioritises performance and occupant health, you get to reduce the amount of chemicals emitted into the air. The equipment will remain clean. You will get potential operational benefits.
What Should You Consider When Installing UVGI In HVAC System?
When it comes to process, most of you might be thinking, “Oh, it must be like placing a UV lamp inside a unit like light bulb inside a holder and then expect results.” It isn’t. You need proper planning to make sure this technology performs immaculately and delivers long-term value.
Here are some tips to keep in mind when adding UVGI system in HVAC:
Installation location
Ah, one of the key factors… UV-C lamps can be placed close to cooling coils, near drain pans, near air handling units, or within ductwork, depending on the purpose. Correct positioning ensures optimum exposure & effectiveness.
Building requirements
Each building has a unique HVAC configuration and air quality objectives. Meaning, a hospital might need a UVGI strategy compared to a manufacturing facility. Always assess the specific requirements of your property first. Do not just assume.
HVAC system compatibility
All HVAC systems are not created equal. Ensure compatibility of the UVGI solution with your existing equipment and airflow arrangement before installation.
Maintenance requirements
While UVGI systems are relatively low maintenance, UV lamps eventually become less effective and need replacement. It is important to be aware of the investment value of a building prior to investing. That way, you can understand its maintenance value.
Safety considerations
Proper placement and operation of the UV-C light source are necessary for avoiding unintended exposure. Work with experienced professionals in the HVAC industry. You can be assured of safe and compliant installation.
Professional design and installation
Safety isn’t the only benefit of having a pro with you. They can also design a professional system, make the right lamp selection and follow industry-standard installation practices. These are often the deciding factors in whether the UVGI system in HVAC will deliver intended benefits or fall short of expectations.
