Siemens PolyCool for superheat and capacity control is the ideal solution for advanced energy saving applications. The superheat controller is available on its own or in a package comprising controller, magnetic refrigeration valve, pressure sensor and temperature sensor.

Polycool Superheat Controller

• standalone controller
• maximum operating pressure integrated with monitoring of sensors and minimum superheat
• control can be included in the safety circuit or configured separately
• 24Vac power supply

Using the Polycool package, superheat can be maintained at a constant level independent of refrigeration capacity or it can be increased to reduce capacity, reducing compressor cycling and providing full modulation control. Polycool can also be employed to monitor minimum superheat and provide alarms and protective plant shutdown.

Polycool Package Solutions

• comes ready for mounting (plug and play)
• superheat algorithm: PI or PID
• capacity range: 29 - 740kW
