Microbial Challenges Within HVAC Systems

Common problems in HVAC systems include:

• Microbial growth on cooling coils and drip trays
• Biofilm formation, reducing heat exchange efficiency
• Bacterial and mold spores spreading throughout the room via air ducts
• Increased maintenance frequency and operating costs

Why Introduce UV LED Technology into HVAC Systems?

Core functions include:

• Inactivating bacteria, mold, and viruses
• Inhibiting biofilm formation on cooling coil surfaces
• Reducing the microbial load in the system's circulating air

How UV LEDs Work in HVAC Systems

Contaminated air enters the HVAC unit:

• The UV LED module irradiates the airflow and critical components.
• The UV-C band disrupts the DNA/RNA structure of microorganisms.
• Microorganisms lose their ability to replicate and spread.
• The air inside the system and the surface of the coils remain cleaner.

• Before or after the cooling coils
• Drain tray area
• Supply or return air section (depending on system design)

Performance Data and Technical Characteristics (Examples)

Typical Technical Parameters of UV LED HVAC Systems (depending on application conditions):

• Wavelength Range: 265–280nm
• Microbial Inactivation Rate: >99% inactivation rate for common bacteria under specific irradiation conditions
• Lifespan: 20,000–30,000 hours
• Operating Mode: Continuous operation or periodic control
• Ozone Generation: None (below detection limit)
