The Bitron 550 LM is a powerful 550 watt UVC clarifier that is used to reduce suspended algae and pathogens in bodies of water to 250 m³ in volume. Due to the low flow speed relative to UVC performance the displaced water is freed from suspended algae and germs in a particularly effective manner. This means that the water does not need to be re-circulated so frequently, and thus expenditure of energy is reduced. Stainless steel reflectors intensify the performance of the UVC bulbs. The Bitron 550 LM is operated as a flow-through UVC above the water level. It can be ideally implemented in combination with the different modules of the Proficlear filter system.
