Sterilight® Platinum Series Flow Rate vs UV Dose Sizing Your System

The UV dose delivered by a given reactor is dependent on many factors, including water quality and flow rate. NSF/ANSI Standard 55 requires that the UV system deliver a minimum UV fluence of 40 mJ/cm2 at the alarm set-point. The accompanying graph shows how the delivered fluence will be affected at varying UV transmittance levels.

It is strongly recommended (by all UV manufacturers) for maximum efficiency of your UV Sterilization, that you pre-filter your water with a 5 Micron sediment cartridge.

Do not connect plastic pipe or tubing directly to the UV system because the UV light will break down plastic over time. The best way to make the connection is with Dielectric Unions that allow for a connection from stainless steel to copper, that will not corrode.
