Jurisdictions globally are confronting climate change and recognizing that building decarbonization is an important component in their efforts.


Environmental Coil Optimization destroys the insulating biofilm to ‘release’ dirt and debris that contribute to coil fouling. Coil optimization returns the Air Handling Unit (AHU) to as-new specification to help achieve the benefits listed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), while providing substantial and immediate energy efficiency that results in rapid ROI payback.

UVC for Increased Energy Efficiency and Reduced Maintenance

Incorporating UVC technology into building air conditioning systems has many benefits.

  • Improves indoor air quality (IAQ) and employee performance.

  • Eliminates insulating biofilm to improve heat exchange and airflow, which has been proven to reduce Air Handling Unit (AHU) energy consumption by about 20%.

  • Reduces workload and improves efficiencies.

  • Eliminates biological growth on coils and in the drain pan that can cause coil fouling and odors.

  • Increases AHU equipment life.

  • Mitigates risk, liabilities, and cost.

  • Achieves a measurable return on investment (ROI) within one to three years. (Based on usage and energy costs.)

In-AHU and In-Duct UV fixtures, such as the Lumalier AR Series UVC Fixtures, are installed inside ventilation systems. In addition to providing high-level, facility-wide disinfection of airborne infectious pathogens, these fixtures provide facilities with other important benefits.


“UVC can be readily applied to HVAC systems to keep coils, drain pans, and other surfaces clean and free of microbial contamination. UVC maintains heat exchange efficiency, design airflow, and improves indoor air quality by reducing bacteria and mold growth on system components.” “Coil pressure drop is reduced and, therefore, airflow is restored. Because heat transfer also is restored, this combination can result in significant energy savings, with payback of possibly less than 2 years.”

Maintenance Benefits

1. Eliminates need for chemical coil cleaning = labor and chemical savings.

2. Eliminates need for pan pills or odor pills in pans or plenums.

3. More efficient system = fewer service issues. Lifecycle of AHU extended by approximately 2 years
