DEMAMaster probeless systems automatically inject chemicals based on programmable timing routines that will cycle the pump on and off when receiving a trigger signal. DEMAMaster speed control systems inject continuously when a trigger is received and use a speed to control to set the pump rate. Probeless systems are ideal for CIP, maintaining chemical concentration in a tank and or reservoir, and are easy to program with traditional analog programming. DEMAMaster is housed in DEMA’s a spray resistant, durable enclosure that includes DEMA’s quick-change pump for easy squeeze tube replacement.
