Steril-Aire UVC Emitters

Why Choose Steril-Aire?

Steril-Aire's UVC Emitters™ work better and last longer. Independent testing proves that our UVC Emitter output is significantly higher than the competition at all temperatures.

Only Steril-Aire delivers:

3-4 times longer life: The Steril-Aire UVC Emitter has a 12-month service life — and even after a full year, it has 2-3 times greater output than competitive devices deliver on day one! As a result, only Steril-Aire can ensure the germicidal performance you need, with no return of microbial growth up to 4 times longer than the competition.
Independently verified output: Steril-Aire has been independently tested to deliver an average of 6 times the output of other ultraviolet devices under HVAC operating conditions. The EPA/Department of Homeland Security reports that Steril-Aire UVC devices achieved 99.96 % destruction in a single pass on airborne bacteria, 99 % on viruses and 96 % on spores.
Used in all major hospitals and the Biopolis Biomedical Research Hub in Singapore because of its excellent germicidal performance.
Proven energy performance: Steril-Aire has achieved significant energy savings in HVAC systems in USA and in Singapore. Energy savings of up to 21% has been achieved in chiller plant performance in Singapore – a direct result of improved heat transfer efficiency at the cleaner cooling coils.
A patented state-of-the-art solid state electronic power supply for enhanced reliability and performance.
High performance construction, including stainless steel housings with high spectral aluminium reflectors, and thick-wall quartz tubes.
A full array of lamp sizes and configurations to fit the widest range of applications — externally mounted, internally mounted, and portable.
Complete technical and engineering support with in-house expertise in both HVAC technology and microbiology, delivering real science for clean air. Our patented installation ensures the germicidal performance for your application.

Benefits of Using UVC

Steril-Aire's systems-engineered germicidal UVC Emitters installed in HVAC systems provide a proven and cost-effective tool to reduce energy consumption and operating costs while improving indoor air quality.

Installed at the cooling coil and drain pan in an HVAC system, UVC eliminates surface biofilm — a complex matrix of mould, bacteria, viruses and debris.

Why should you consider using Steril-Aire UVC in your building?


The Petri dish samples (top row), taken from an HVAC coil, demonstrate high concentrations of bacteria, mould and yeast. After exposure to a UVC Emitter (bottom row), these microbes are almost completely eliminated.

Energy Savings: Lowers energy costs by improving HVAC system heat transfer and increasing net cooling capacity.
Maintenance Savings: Continuously cleans coils, drain pans, plenums and ducts, reducing or eliminating manual cleaning and the use of harmful chemicals.
Improved IAQ: Creates a safe, comfortable and healthy working environment.
Improved Employee Productivity: A reduction of half a day of sick leave per employee per year will pay for the Steril-Aire UVC investment.
Water Conservation: Reclaiming clean condensate for cooling tower makeup, irrigation or grey water flushing reduces water and waste water costs.
Extended food shelf life: Reduces food spoilage.
Rapid Return on Investment: Offers a return on investment in less than 2 years.
LEED and Green Mark Contribution: UVC contributes to LEED and Green Mark points under the ‘innovation' category.

Germicidal UVC Products

Model DE Series UVC Emitters™

Steril-Aire's Double-Ended fixtures are ideal for internal installation in medium to large air handling systems in commercial, industrial, health care and institutional buildings.

Model DE fixtures may be mounted singly, in built-up banks or in parallel configurations in a variety of locations, including coils, drain pans, ductwork, mixed air plenums and exhaust systems. DE Fixtures may also be ceiling or wall-mounted for specialty applications in health care and food processing.

The DE Series is available in six lengths (18", 24", 30", 36", 42" and 62"), 110-277 V, 50/60 Hz, providing installation flexibility to accommodate virtually any system.

Model SE Series UVC Emitters™

Steril-Aire's Single-Ended Emitters are ideal for external mount in fan coils, heat pumps, unit ventilators, terminal units and ductwork.

Steril-Aire Single-Ended (SE Series) fixtures are installed from the exterior of HVAC equipment, making them ideal for difficult to access sites.

These germicidal lamps are easily installed with a one-inch hole in the equipment wall and/or duct, and then simply mounting the fixture to the unit exterior. Only the lamp or tube penetrates into the system, while the power supply remains external.

The SE Series is available in seven lengths — 12", 16", 20", 24", 30", 36" and 42" — with a 120-277 V, 50/60 Hz universal power supply.

Award-Winning UVC Kit for Unitary Air Conditioners

Steril-Aire's proven UVC technology is packaged into a convenient kit designed for unitary systems of less than 5 tons — ideal for condos, apartments and homes, hotels and motels, dormitories and smaller commercial retail and industrial applications.

Steril-Aire UVC Kit for Unitary Air Conditioners is designed for easy installation in unitary systems of less than 5 tons. It delivers energy savings and improved indoor air quality to retrofit units and maintains factory design efficiency on new units. It is ideal for use in mini-split and ductless systems, split systems, PTAC units and heat pumps with coil sizes up to 15" high by 26" wide.

Components can be selected based on voltage, UVC Emitter length and the widest range of mounting options in the industry. The UVC Kit for Unitary Air Conditioners includes a compact power supply in either 120V or 208/230V, a choice of mounting options and an option from five Emitter lengths — 7.5", 10", 16", 20" and 24".

UVC Kit for Unitary Air Conditioners Benefits:
Improved operating efficiency resulting in energy savings
Eliminates costly, disruptive cleaning programmes
Delivers 2.5 times the output of competitive UVC products
Quick return on investment, often less than one year
Installs quickly, easily and safely

SE Series UVC Ozone Emitters for Kitchen Exhaust

Steril-Aire's Single-Ended (SE Series) UVC/Ozone fixtures are used for kitchen extract ducts to remove odours and grease and to ensure the expelled air does not contaminate the neighbouring environment.

Installation is made by making a 1” hole in the duct, mounting the fixture to the exterior of the duct and cantilevering the emitter tube across the full width of the duct. Subject to proximity of people to the extract duct, additional UVC emitters may be required to eliminate the expelled air. SE UVC/Ozone Emitters are available in seven lengths: (12”, 16”, 20”, 24”, 30”, 36” and 42”) with a universal 120-277 V power supply.

Modular Radiometer Systems

The Modular Radiometer System is designed to monitor UV output intensity of Steril-Aire UVC Emitters™ for precise, instantaneous irradiance readings with reproducible results. The Radiometer System uses a solid-state photodiode detector which is extremely stable with a low temperature coefficient to measure UVC radiation accurately.

The Steril-Aire Radiometer System features a modular structure. It includes a separate Display Module, UV Sensor and Logic Controller, allowing the use of some or all components to fit the needs of the end-user. An extension data cable for the sensor, controller or display and a display holder is available as an accessory. In addition, four bundled KIT options are available that offer easy sensor readings from outside the duct in single or multiple air handler installations or connecting to third party monitoring systems.

Irradiance can be defined in both μW/cm2 as well as user-defined pre-set percentage – functions usually found in much more expense models. It thereby ensures change-out of UVC lamps at optimum intervals, for maximum economy with no compromise in performance.

NIST traceable calibration resides within the sensor for ease of calibration. The Logic Controller provides easy-to-read visual indication of relative UVC Emitter output. It may be used with a portable (hand-held) Display Module to provide digital readout data of relative or absolute power output of the lamp in microwatts/cm2. The Logic Controller is easily connected to HVAC building management systems (BMS) or programmable logic controllers (PLCs) with 4-20 mA, 0-1 V Sensor, Logic Controller, and a NO-NC relay.
