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 uses a proprietary pulsed xenon bulb powered by Violet DefenseTM technology. It is lab verified to kill 99.9% of bacterial and fungal growth up to 6.5 ft away in 1-2 hours. 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 45W of energy and has a run time of two hours a day, saving thousands of dollars per year in energy in large buildings.
With lower maintenance requirements and built-in occupancy sensors, the Puro solution is safer by eliminating the risk of damaging light exposure. Our lamps do not require a kill switch, and though unnecessary, can even be unplugged if there is a fear of exposure while performing routine maintenance.
The Total Cost of Ownership over 5 years is 1/3 the cost when using Puro’s fixtures (see table). At a run time of 2 hours per day, these lamps have a projected 5-year life span and eliminate the maintenance cycle. In large buildings with 60-70 AHUs, this results in massive time and maintenance labor savings. This breakthrough in UV technology is making UV systems more energy and cost efficient, easier to maintain, and delivering long term value for the owner and operator.
