A hospital study demonstrated that high-intensity UVC installed on HVAC coils significantly improves heat transfer, reduces system energy consumption, and delivers measurable return on investment.
Discover what UVC could save in your building.
Biofilm and microbial growth naturally develop on HVAC coils. Over time, this contamination reduces heat transfer efficiency and forces the system to consume more energy.
Continuous UVC irradiation prevents microbial buildup and keeps coils clean without chemicals or manual intervention.
In the hospital study, coil performance improved quickly:
+15.6% increase in thermal conductance after only 7 weeks of UVC operation
Cleaner coils allow better heat exchange, improved airflow, and more efficient HVAC operation.
UVC reduces HVAC energy consumption
When coil surfaces remain clean, the entire HVAC system operates more efficiently.
The hospital study measured significant reductions in energy consumption across the air-handling system:
These improvements translate into measurable operational savings and lower building energy demand.
The hospital study also confirmed strong financial performance:
Every HVAC system is different.
Energy savings depend on airflow, coil size, operating hours, climate conditions, and system configuration.
To help engineers evaluate UVC integration in their HVAC systems, Sanuvox developed a UVC coil cleaning sizing platform.
This tool allows you to:
• Size the correct UVC solution
• Determine the optimal number of lamps
• Estimate potential energy savings
• Configure the system for your project
Sanuvox IL Coil Clean are designed to continuously irradiate HVAC coils with UVC, preventing biofilm formation and maintaining peak performance.
Life Cycle Cost (LCC) analysis from the hospital study confirmed that UVC coil treatment is a cost-effective HVAC strategy.
The analysis projected:
$27,719 in savings over 10 years
When maintenance savings (labor, chemicals, and water) are included, ROI increased to 49% with a payback of just 2.04 years.
Continuous UVC exposure significantly reduces microbial growth on HVAC coils.
The study measured:
• 99%+ reduction for most pathogens tested
• 94% reduction for resistant strains
Including bacteria relevant to healthcare environments.
For more than 30 years, Sanuvox has been developing high-performance UVC solutions for HVAC systems worldwide.
