UV for AHU

Until recently, low-pressure mercury vapor or fluorescent UV-C lamps have been the best option for disinfecting the cooling coils in AHUs. These lamps are low intensity, must run continuously (24/7) and be mounted at a close distance (4”-6”) to coils and filters. There’s a faster, safer, and more effective solution. A single Helo F1 fixture, powered by Violet DefenseTM technology, uses a proprietary pulsed Xenon bulb. It is lab verified to kill up to 99.9% of bacterial and fungal growth up to 6.5 ft away. The installation is simple and only requires an electrical outlet. Pulsed xenon lamps are more efficient at generating UV radiation therefore the wattage is significantly lower. A single Helo F1 unit consumes 60W of energy and has a recommended run time of four 30-minute cycles per day, saving thousands of dollars per year in energy in large buildings.
