Henry Technologies S-7721 Accumulator R-407A or "squealing" sounds during startupThe Henry Technologies S 7721 is a high capacity vertical suction accumulator engineered for industrial refrigeration and large scale HVAC systems. Featuring 2 1 8" ODS connections, this vessel is a critical defensive component designed to mitigate liquid slugging by ensuring only refrigerant vapor reaches the compressor. This suction line accumulator functions as a temporary reservoir, utilizing a precision engineered U tube design to separate the
