UV-plants of the PURION® product line are characterized by compact construction and a high degree of efficiency respecting to disinfection and energy consumption. The construction design follows laws, standards and regulations.


UV-plant PURION 400 can be equipped with a polished stainless steel reactor. PURION 400 can be used to disinfect drinking water up to a flow rate of 300 l/h and for a transmission of at least 90% per cm. The used uv lamps are characterized by a long durability and a high degree of efficiency respecting to disinfection and energy consumption.

The power supply can be carried out with 230 V/50 Hz or optionally 12 V DC, 24 V DC or 110 V AC. The compact construction design enables an easy replacement of the uv lamp at the end of their useful life. You don't need any tool. Also replacement and cleaning of the quartz pipe can be arranged easily.

UV disinfection is reached by floating the water through the reactor. Inside the reactor an uv lamp enclosed in a uv-c transparent quartz pipe is surrounded by the drinking water to be treated. The small distance of 7.5 mm between the quartz pipe and the inner surface of the reactor ensures optimal irradiation and therefore optimal disinfection of the water.
