Steril-Aire high-output UVC devices continuously eliminate over 99.9% of airborne pathogens — including mould, bacteria, viruses, VOCs, and odours — directly within HVAC systems. This improves indoor air quality (IAQ) and reduces occupant exposure to harmful microbes.

By destroying contaminants at the coil and in the air stream, Steril-Aire ensures that clean, healthy air is delivered to all occupied spaces, supporting compliance with AS1668.2 ventilation standards and improved building health outcomes.

Steril-Aire’s high-output UVC technology destroys airborne mould spores and surface growth on coils, drain pans, and ductwork. Continuous UVC exposure prevents regrowth, maintaining hygienic, odour-free HVAC systems.

Mould spores drawn in from outside or return air are neutralised before they circulate through the building, helping to protect occupant health and maintain system efficiency.

Biofilm is a sticky microbial layer that coats HVAC coils and drain pans, reducing energy efficiency and air quality. Traditional chemical cleaning often cannot reach deep within the coil.

Steril-Aire UVC penetrates the coil surface, breaking down and eliminating biofilm while preventing it from reforming — restoring optimal heat transfer and airflow performance.

Organic growth and biofilm can block coils and reduce HVAC system performance. Steril-Aire’s germicidal UVC energy penetrates coil fins to remove biological blockages, restoring airflow and efficiency.

Restricted airflow reduces system performance and occupant comfort. Steril-Aire’s high-output UVC emitters remove microbial buildup that impedes airflow through coils and filters.

Field tests show an average airflow improvement of 12.73% exclusively using Steril-Aire UVC, helping fans operate more efficiently and maintain design air volumes.

Microbial contamination increases system resistance and static pressure, forcing fans to work harder and consume more energy. Steril-Aire exclusively removes this growth from coil surfaces right through the coil,. Steril-Aire’s high output UVC improves system pressure drop by an average of 18.89%, delivering measurable energy savings and reduced wear on fan motors.

As Steril-Aire restores coil cleanliness, heat transfer efficiency improves dramatically. Systems regain their designed cooling capacity, enhancing thermal comfort and reducing compressor load.

Average coil heat transfer improvement achieved exclusively through Steril-Aire high-output UVC is 36.1%, verified in field applications.

By continuously removing organic buildup and controlling moisture, Steril-Aire UVC reduces corrosive conditions that damage coil fins, drain pans, and metal components. This extends HVAC equipment life and reduces the frequency of costly coil replacements.

Steril-Aire provides a chemical-free, automatic cleaning solution that keeps coils and drain pans disinfected 24/7. Continuous UVC exposure eliminates microbial growth, removing the need for manual chemical cleaning and reducing maintenance downtime.

Steril-Aire UVC achieves 99.9%+ destruction of airborne viruses and bacteria, including COVID-19 and influenza, as air passes through the HVAC system. This adds a powerful layer of infection control and ensures supplied air is essentially pathogen-free.

Cleaner HVAC systems mean cleaner, healthier air for building occupants. Steril-Aire UVC reduces allergens, odours, and pathogens, supporting better respiratory health, workplace wellbeing, and compliance with modern IAQ and wellness standards across commercial, healthcare, and education environments.

Contaminated coils reduce heat transfer and airflow, driving up energy use. Steril-Aire UVC eliminates biological growth that causes inefficiency, allowing fans, compressors, and pumps to operate at optimal performance. Cleaner coils deliver measurable energy savings and lower operating costs, while also supporting NABERS and Green Star performance targets for sustainable buildings.

Steril-Aire facilitates improved air cleaning efficiency by removing pathogens and organic contaminants from the conditioned air stream. This supports reductions in minimum outside air requirements, improving HVAC system energy performance under AS1668.2 – The use of ventilation and air-conditioning in buildings.

Steril-Aire enhances equivalent clean air delivery by removing airborne pathogens through HVAC disinfection. This helps facilities meet ASHRAE 241-2023 standards for reducing infectious aerosol risk and maintaining healthy indoor environments through mechanical ventilation systems.

Frequently Asked Questions — Steril-Aire UVC in HVAC Systems

How does UVC improve indoor air quality in HVAC systems?

Steril-Aire UVC emitters use high-output germicidal light to eliminate airborne and surface pathogens inside the air handling unit. By destroying mould spores, bacteria, viruses, and VOCs at the coil and in the airstream, Steril-Aire improves indoor air quality (IAQ) and helps deliver cleaner, healthier air throughout the building.

Is UVC safe for use in air conditioning systems?

Yes. Steril-Aire UVC systems are specifically designed for installation within HVAC equipment. The UVC light is contained inside the air handling unit, so there is no exposure risk to building occupants or maintenance staff. All devices meet recognised safety and electrical standards for Australian mechanical services applications.

How long does it take for Steril-Aire UVC to clean a contaminated coil?

Cleaning time depends on the level of contamination, but most coils show visible improvement within 30 to 90 days of installation. During this period, Steril-Aire’s high-output UVC energy penetrates the coil depth, removing biofilm and organic buildup that restrict airflow and heat transfer.

What energy efficiency improvements can Steril-Aire deliver?

Field data shows that Steril-Aire UVC can achieve:

AHU Total 84
Pressure Drop Average 18.89%
Heat Transfer Average 36.10%
Airflow Average 12.73%

These improvements translate to measurable reductions in fan, compressor, and pump energy consumption — helping buildings lower operating costs and improve NABERS and Green Star performance ratings

Does Steril-Aire UVC help with mould and odour problems?

Absolutely. Mould and odours originate from microbial growth within coils and drain pans. Steril-Aire UVC destroys mould spores and organic residue, preventing regrowth and eliminating odours at their source. This keeps HVAC systems hygienic and odour-free without the need for chemical cleaning.

Can UVC assist with AS1668.2 and ASHRAE 241-2023 compliance?

Yes. Steril-Aire UVC supports AS1668.2 ventilation requirements by improving air cleanliness and enabling potential reductions in outdoor air rates, which can reduce energy use. It also aligns with ASHRAE 241-2023, helping deliver higher “equivalent clean air” to reduce the risk of airborne disease transmission in indoor environments.

What makes Steril-Aire different from other UVC products?

Steril-Aire pioneered high-output UVC for HVAC systems and remains the global benchmark for germicidal performance. Independent testing confirms that Steril-Aire produces up to 6 times the output of conventional UVC devices in HVAC operating conditions (10°C, 2 m/s air velocity) at end of life, ensuring consistent microbial control and measurable efficiency gains.

Where is Steril-Aire UVC used in Australia?

Steril-Aire UVC is widely installed across hospitals, laboratories, universities, aged care, offices, retail, and food processing facilities. It’s trusted by building engineers and facility managers seeking proven HVAC hygiene, IAQ improvement, and energy efficiency results throughout Australia and New Zealand.

Does UVC replace regular HVAC maintenance?

Steril-Aire UVC perpetually cleans coils, drain pans, and other surfaces, eliminating manual coil and drain pan cleaning and chemical use, as well as reducing duct cleaning and assisting with decreased corrosion.
Regular mechanical inspections and filter changes are still essential. The result is a cleaner, lower-maintenance HVAC system with longer component life and better long-term performance.
