i-controls, of Bellevue, Wash., introduces the Cube, an advanced RO control system housed in an octal-style relay housing. It’s the perfect upgrade from relay-based controls or as a replacement for unserviceable proprietary controllers. It provides pressure and tank switch inputs with outputs for a motor (up to 1.5 horsepower) as well as feed and flush solenoids. The product incorporates advanced filter circuitry and surge suppression, a robust power supply, and a rugged tech-friendly housing.
