Within the air conditioning system you will find expansion valves and orifice tubes. These lower the pressure and temperature of the refrigerant as is passes through the meters, fixed and variable orifice. The orifice tube also acts as a filter for the system, trapping any debris that may restrict the flow of refrigerant. Because the orifice tubes can become blocked we strongly advise they are replaced when carrying out repair/maintenance on the air con system.
Orifice tubes are also available in convenient sized stock packs, offering you a selection of common tubes that can be stored efficiently without the time delay of ordering as it is a high use application. With a vast range of expansion valves and orifice tubes Four Seasons UK are able to cover the majority of applications.
