Refrigerant circuit and expansion valve

Manufactured from top quality materials by skilled personnel according to strict procedures of brazing, and conforms to Directive 97/23. It comprises:

·         Scroll compressors designed for R410A;

·         Evaporator made from AISI 316 stainless steel brazed plate,

·         copper and aluminium condensers;

·         Filter dryer;

·         Flow sight glass with moisture indicator;

·         External equalisation thermostatic expansion valve which regulates the injection of liquid refrigerant into the evaporator. The injection is a response to the refrigerant overheating. The range of thermostatic valves that we use are designed for specific applications and are connected to the circuit via bi-metal brazing;

·         High pressure switch with manual reset;

·         Low pressure transducer with semi-automatic reset;

·         Gauges for high and low pressure;

·         Pressure connections for checks and maintenance.

 

Hydraulic circuit. The hydraulic circuit consists of an internal evaporator and pipework. It features a differential pressure monostat that protects the evaporator in case of a no water flow.
