Refrigerant circuit

This is manufactured from top quality materials by skilled personnel according to strict procedures of brazing, compliant with Directive 97/23. It is composed of:

– rotary (CWT007 and CWT010 models) and scroll compressors designed for use with R410A;

– evaporator assembled from AISI 316 stainless steel brazed plate,

– condenser assembled from micro channel aluminium ;

– filter dryer;

– flow sight glass with moisture indicator

– external equalisation thermostatic expansion valve. The thermostatic expansion valve 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;

– unidirectional valves (only for multi-compressor units);

– high pressure switch with manual reset and low pressure switch with automatic reset;

– high and low pressure manometers;

– pressure connections for checks and maintenance.

Hydraulic circuit

This consists of an evaporator and interior piping to the machine, it also includes:

– an storage tank made of carbon steel and thermally insulated;

– an electric stainless steel, thermally insulated pump;

– a water bypass to prevent incidents

– caused by the erroneous closure of the stop valves;

– expansion vessel;

– safety valve;

– automatic vent valve;

– water-level sensor

– water differential pressure switch;

– stop ball valves;

– inlet unit water filter;

– manometer;

– drain valve.
