Ultra Pure 1000/1225/1400/2000/2500 RODI system is designed to treat larger amounts of water. This system requires a 3/4HP induction motor driving a stainless steel impeller pump to deliver required water throughout the system. We have integrated a UL listed controller isolated from any water including a solenoid to energize incoming city water during operation and close when tank is filled automatically. If any water is detected within cabinet our automatic leak detector will shut off incoming water and alert both audible and visual alarm of water detected. Each cabinet was carefully designed for simplicity of installation and filter maintenance.
