Designed to control two or more chillers through a PLC, programmed to operate in facilities where there’s need for back-up and automatic relay. The QRD conducts the automatic control system with digital display of their pressure, flow and temperature. Control the temperature of the process is fundamental to guarantee data accuracy in diagnosis, and to not undermine the main equipment by operational wear at inappropriate temperatures.

Main components:

• PLC controller with HMI;
• Audible alarm siren;
• Red LED indicating failure with a button that silences the alarm;
• Digital flowmeter and liquid display 1 “.
