UV-C Systems Inside AHUs: Design Benefits and Limitations

UV-C systems inside Air Handling Units are becoming a useful add-on for improving coil hygiene, reducing biological growth, and supporting better HVAC reliability.

But UV-C is not magic. It must be designed, installed, controlled, and maintained correctly. (UV-C Systems Inside AHUs: Design Benefits and Limitations)

🔹 What UV-C Does Inside AHUs

✅ Helps reduce biofilm on cooling coils

✅ Controls microbial growth on wet surfaces

✅ Keeps drain pans cleaner

✅ Reduces odor risk from biological buildup

✅ Supports better coil heat transfer over time

✅ Helps maintain lower airside pressure drop

✅ Improves long-term AHU hygiene
