Sterilight Copper Series Point-of-Use Ultraviolet (UV) Water Purifier

The Sterilight's Copper Series UV sterilizers are "entry level" systems designed for optimal cost effectiveness for basic point-of-use applications. It is a popular choice as post treatment after a residential under-sink reverse osmosis system or other under sink carbon filter, or for treating water at a single faucet, water fountain, or similar application.

Although the Copper Series is designed to be economical, all Copper Series units feature an integrated ballast/lamp connector with visual "lamp on" indicator light, a stainless steel reactor chamber, combination plumbing ports with 3/8"FNPT (female NPT) / 1/2" MNPT (male NPT) for easy installation, a fire-polished domed quartz sleeve, and Sterilights' popular Sterilume™-EX coated low pressure germicidal UV lamp which can be easily changed without interrupting the water flow.

Three models are available to treat flow rates up to 2.8 gallons per minute (at UV dose of 40 mJ/cm2).

Pre-treatment Requirements:

All UV sterilizers required sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could "hide" behind a sediment particle in the "shadow" of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller.

Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm or manganese levels exceeding 0.05 ppm should also be treated to prevent staining of the UV sleeve.

Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 75% after the above-mentioned pre-treatment, activated carbon filtration may be desirable to improve UV transmittance. The majority of deep wells have a UVT of 85% or greater. If your UVT is unknown, select a model with a higher flow rate capacity then you feel you will really require (this will provide a higher UV dose at your desired flow rate), or add an activated carbon pre-filter to your system.

Accessories:

The Sterilight Copper Series can be equipped with a flow restrictor to ensure that you do not exceed the maximum flow capacity of the system. We recommend that you choose a flow restrictor rated for slightly less flow than the UV sterilizer based on a UV dose of 40,000 μWs/cm2. For more details, review our flow restrictors page.
