Quick Answer
The Alpha UV UVGI System for AHU/HVAC is an in-duct Philips UV-C installation for air handling units — coil irradiation or airstream disinfection — that kills airborne viruses (including SARS-CoV-2), bacteria, and mold spores at 5–40 mJ/cm² UV dose, with safety interlocks and UV intensity monitoring. Designed to ASHRAE 62.1 and CDC HICPAC guidelines.
UV germicidal irradiation for air handling units — kills airborne viruses, bacteria, and mold
UVGI (UV Germicidal Irradiation) for AHU/HVAC is an in-duct UV-C installation that irradiates the airstream as it circulates through your ventilation system. Two configurations are available: coil irradiation (lamps near the cooling coil, preventing biofilm that degrades heat transfer and circulates mold spores) and airstream disinfection (lamps in the main duct, inactivating pathogens in moving air). Alpha UV System UVGI systems are designed from measured duct dimensions and airflow data — UV dose delivery at typical duct face velocities of 2–3 m/s requires precise lamp placement geometry that our IIT Patna engineers calculate from first principles.

Every Alpha UV System reactor geometry is validated through CFD simulation using ANSYS Fluent. The analysis below shows velocity streamlines and UV dose distribution across the reactor cross-section, confirming that minimum dose targets are met across the entire chamber volume — not just at the chamber centreline.

Every UVGI AHU ships with genuine Philips UV-C lamps. Not unbranded Chinese alternatives. Philips lamps are rated 9,000–12,000 hours — more than double the life of typical Chinese OEM lamps. A serial number certificate of authenticity is included with every lamp.

Yes. SARS-CoV-2 is inactivated at UV-C doses of 5–20 mJ/cm² — well within the design range of Alpha UV UVGI systems. Placement geometry is calculated by our IIT Patna engineers for your specific duct dimensions and airflow velocity to ensure the target dose is delivered.
Coil irradiation places lamps near the AHU cooling coil to prevent biofilm growth — this both stops mold spores from being circulated and improves heat-transfer efficiency by 10–25%. Airstream disinfection places lamps in the main duct to inactivate pathogens in moving air. Many installations use both.
Yes. Every Alpha UV UVGI system includes a safety interlock that automatically shuts off the UV lamp when the AHU access door or panel is opened — preventing accidental UV-C exposure during maintenance.
Yes. Alpha UV UVGI systems are designed for in-duct retrofit installation into most existing AHU configurations — installation is done through the AHU access panel with minimal ductwork modification.
