Carrier 06DA660181 Pressure Suction Unloader

The Carrier 06DA660181 Pressure Suction Unloader, which is an essential component of the Carrier air conditioning systems. It operates based on controlling the amount of pressure as well as the vacuum in the refrigerant circuit. This in turn helps to achieve the better output and protect the compressor, which is the central part of the system. At start up of the system the unloader is used to bypass the compressor to avoid high pressure build up. When the system has achieved the right operating conditions, the unloader disengages and lets refrigerant to pass freely through the compressor. It also avoids subjecting the compressor to undue fatigue during start up and the process runs efficiently.
