Chenery Technical Services are your specialists in the installation and servicing of Ultra Violet Light Water Purification Systems.

The UV disinfection process occurs as water passes through a specially designed germicidal irradiation chamber. Micro-organisms in the water are inactivated or killed when the UV light is absorbed. Typically UV treatment units have been tested to achieve a 99.9% kill rate of e-coli and faecal coliforms.

UV lamps (bulbs) require annual replacement to ensure optimal performance. UV lamp performance, just like any other light source, will slowly diminish over time. Beyond one year, there is no assurance that the UV light emitted from the bulb will provide sufficient disinfection.

Chenery Technical Services schedule lamp replacement to coincide with your annual backflow prevention IQP visit.
