More Information
Summary:An apparatus for refrigeration system control includes a plurality of circuits, each circuit having at least one refrigeration case and an electronic evaporator pressure regulator in communication with each circuit. Each electronic evaporator pressure regulator controls a temperature of one of the circuits. A sensor in communication with each circuit measures a parameter from the circuit. A controller associated with each electronic evaporator pressure regulator controls the respective electronic evaporator pressure regulator based upon measured parameters from each of the circuits.
