Ultra Violet Sterilisers

There are more than half a million people in the UK whose only source of drinking water is from a private water supply – these sources fall into one of three main categories: wells, springs / streams and boreholes. Our ultra violet (UV) sterilisers can help you obtain bacteria free drinking water from these untreated supplies.

UV light destroys the cell DNA (or RNA in the case of viruses) making the micro organisms inactive. Our water sterilisers employ a low pressure mercury vapour discharge lamp surrounded by a water jacket whose inner wall is made from a special UVC transparent quartz material. the lamp produces a very strong spectral line at 254 nm in the shortwave UVC region, which is the waveband most lethal to micro organisms.

Our units use a stainless steel water chamber maximising full use of the available ultra violet energy resulting in long exposure times and high UV doses whilst minimising UV light absorption into the chamber wall.

Please note that UV sterilisers do not improve the taste of the feed water. They should be incorporated into a system comprising the appropriate water filters to remove particles and to treat the water to make it palatable. Our highly trained staff can advise on the appropriate system to meet any combination of feed water flow and quality.

We’re pleased to offer a new range of 5 economy U.V. systems.
Recognising the benefits of stainless steel for U.V. chambers, we now offer a complementary range from a lower cost source, while still retaining the CE and pressure ratings required.
