Copper capillary tube 15m roll 1 x 2mm

It is used in refrigeration systems. It is the simplest type of expansion device, as it consists only of a tube (generally copper), which acts by having a large pressure drop, due to its small diameter, so that the refrigerant liquid loses most of the pressure that comes from the compressor, pressure that maintained its reduced volume; by losing pressure, it expands at the outlet toward the evaporator. The pressure drop caused by the capillary at this point is defined based on its length, and will correspond to the pressure drop of the system between the condenser and the evaporator.
