EKC 316A is a controller for operation of evaporators on water chillers. The controller and valve can be used where there are requirements to accurate control of superheat and temperature in connection with refrigeration, e.g.: • Processing plants (water chillers). • Cold store (air coolers). • A/C plants. • Regulation of superheat. • Temperature control. • MOP function. • ON/OFF input for start/stop of regulation. • Input signal that can displace the superheat reference or the temperature reference. • Alarm if the set alarm limits are exceeded. • Relay output for solenoid valve. • PID regulation.
