Growth of mold, mildew, and biofilm on coils results in :
Air Handling Unit Coil UV Treatment
Concerns in HVAC Systems :
- About 60% of the energy used by a building is from the HVAC (air conditioning) system.
- High maintenance costs.
- Suspect Indoor Air Quality (IAQ): High proportion of recycled air, airborne microbes, and sick building syndrome.
Typical Problems in the HVAC Evaporator Coils :
- Poor heat transfer between coils and air.
- Deposition and sticking of dust on coils.
- Reduced air flow through the coils.
- Biofilm and dust deposits breed microbes which are then distributed through the ducts.
- Deposits get blown away and accumulate in the ducting system.
Conventional Solutions :
Periodic physical and chemical cleaning of coils is done, which has its own problems :
- Labour intensive.
- Uses strong chemicals (not green). Also wastes water.
- Results in downtime.
- Scrubbing and pressure washing of the coil reduces its life.
A Better Solution - Alfaa UV UltraCOILTM for Continuous Coil Sterilization :
- Maintains a clean and efficient coil without any physical cleaning. Maintains coil in a like new condition.
- Maximizes energy efficiency by maintaining ideal heat transfer across the coil. On average results in a 20%-25% reduction in energy costs (ROI typically < 1.5 years).
- Prevents “blow off” of mold and other microbial growth into the HVAC system which transmits allergens, contaminants, and odors throughout the building’s envelope.
- Strong germicidal action of UV kills microbes and improves IAQ.

UVGI BENEFITS :
UVGI helps save energy on three fronts :
- Fan energy
- Cooling energy
- Maintenance costs
- In addition UVGI significantly increase the lifetime of the coil
- On an average, UVGI results in net savings/ efficiency improvement of anywhere between 10-15% of the HVAC energy costs in a typical system.
- Typical ROI is within 1.5 years!
