Expansion valves, choke nozzles
Thermotec Expansion valves and choke nozzles
Expansion valves and choke nozzles are installed at the junction of the dehumidifier and the evaporator. They are the last components in the system where the coolant is transported at a high pressure. After passing it, the cooling circuit enters the low-pressure phase. In addition to being a pressure barrier, the valve or the nozzle plays another key role.
Expansion valves and choke nozzles in the car AC system allow the coolant to reach a pre-set temperature in the evaporator. The coolant flow is regulated by the expansion valve depending on the temperature of the coolant at the evaporator outlet and based on the parameters indicated by the servo unit. Thus, the automatic AC is capable of cooling the air blown into the cabin to a very precisely specified level.
Replacement of the expansion valve or choke nozzle is necessary whenever the AC compressor seizes up.
Thermotec expansion valves and choke nozzles with ISO standards
The AC system cannot operate effectively without expansion valves or choke nozzles as they allow control of the temperature of the air blown into the cabin. That is why we could not possibly afford to not include them in our offer. Thermotec parts are designed for a wide range of passenger cars, commercial vehicles and trucks available in Europe, and they meet the stringent requirements of the ISO 9001:2008 standard.
