The IWE SS range of ultra violet systems all utilise low pressure mercury vapour discharge lamps to produce ultra violet light at the 254 nm wavelength (UVC) which is lethal to micro-organisms. The stainless steel chamber incorporates a high purity quartz sleeve around the lamp. As water passes through the chamber, UVC light penetrates and destroys the cell structure of micro-organisms in the water.
The selection tables below show the maximum flow rates using good quality water. For guidance on sizing please contact us.
