School UV Water System

Our Schools Category is for situations where there is a Statutory requirement to comply with NSF.

NSF is an American organisation that governs equipment designed to meet its standards:

* NSF42 for improving water asthetics

* NSF53 for removing harmful substances

* NSF55 for micro biologically safe water (ClassA at 40 mJ/cm2) (ClassB at 16 mJ/cm2)

NSF approved systems are considerably more expensive due to certification cost, and the required additional componetry. They also are flow rate restricted so that the water usage flow rate does not exceed the dosage rating.
