Hallett 500PN NSF Certified For Potable Water Flows Up To 16.5 GPM

The UV PURE® Hallett Model 500PN UV with Crossfire Technology® is the industry leader in disinfection for even the most challenging water quality conditions due to automatic self-cleaning wipers and automatic purging to prevent fouling of the quartz sleeves by mineral scaling and biofilm. Since this product is NSF Certified, the Flow Rage is not adjustable. Default Flow is 16.5 GPM. If you do not need a NSF certified unit, the 500P is a better alternative.

UV Pure's patented Crossfire Technology incorporates elliptical reflectors that redirect light energy from 360 degrees to overcome shadowing and deliver a sterilizing UV dose to harmful pathogens. Dual smart UV sensors in every Hallett system continually monitor lamp output and water quality to ensure the highest level of disinfection is consistently achieved. The smart sensors practically eliminate nuisance alarms and make troubleshooting simple when the system is out of compliance.
