Copper capillary tube 6x0.73 mm, Dnipropetrovsk region.

This expansion device does not contain any mechanical moving units and parts and does not require any means of regulation and adjustment, unlike thermoregulating valves (TRV), which ensures its high reliability and duration of operation for a sufficiently long time, as well as its low cost. The numerous advantages of this device explain its choice for equipping various low-power refrigerating units: household refrigerators and freezers, air conditioning systems, small heat pumps, refrigerating cabinets and counters. for sales
