Residential and Commercial UV Water Applications

Our Sterilight UV systems are used in both residential and commercial applications. The Sterilight Silver Series is a compact line of ultraviolet water sterilizers that are ideally suited for point-of-use filtration, reverse osmosis pre- or post-disinfection or with other applications requiring application flexibility. The Sterilight Cobalt Series is ideal for commercial and industrial point of entry applications with high flow rates and constant flow demands for UV treated water.


Bare skin contact with the quartz envelope must be avoided. Compounds from the skin when heated on lamps operating at 600 to 850˚C will form permanent etching (devitrification) on the quartz surface, decreasing UV energy transmission. A contaminated lamp eventually will overheat causing premature failure. Alcohol wipes and rubber gloves are included with every purchase of a quartz sleeve or lamp.  NOTE: In case of contact with bare skin, decontaminate lamp with alcohol wipe before returning to use.
