The Control Freak touch-screen controller from Wanner Engineering is designed to control motor speed for Hydra-Cell pumps. The controller enables the user to enter flow rate, volume in gallons or liters and system pressure in psi or bar. The controller automatically runs the pump manually at the desired flow rate or volume total/time or in preset batches. It can run up to six pumps with one screen and 10 separate batch setup screens per pump. Features include a variable-frequency drive and password protection for pump algorithms. It can also be field calibrated for greater accuracy. The 7-inch color touch screen is in a NEMA-4X (or IP) enclosure and is visible in low-light areas. Operational features include real-time clock, pump-drive information screen, and analog and digital I/O for interfacing with external devices. 800/369-4172; www.hydra-cell.com.
