The highly efficient UVC pre-treatment devices in the Bitron Premium range are suitable for ponds up to 90 m³ and provide extremely powerful removal of algae and pathogenic bacteria – with the same effect as an immersion UVC. 100 % safety against eye damage, particularly energy-efficient thanks to an electronic ballast and exceptionally effective disinfection thanks to the long retention time of the water in the Bitron. A Bitron Premium can be connected flexibly before or after the ProfiClear filter system – i.e. also in other gravitational applications – and additional Bitron Premium UVC units can be added at any time if the pond or fish population increases, as well as being installed horizontally or vertically. Depending on requirements, the lamps in the Bitron Premium 120 W and 180 W can be switched individually.
