Refrigerant Recovery Units
Although McQuay chillers can pump the entire refrigerant charge into the condenser and valve it off, there are
occasions when pumpout units are required, due purely to specification requirements or unusual job
considerations.
McQuay offers two sizes of refrigerant recovery units (Model RRU) and one recovery unit that is factory
mounted on a storage vessel (Model PRU). Recovery units are ETL listed. Capacities for R-22 are ARI
certified. The storage tank is designed, constructed and stamped in accordance with ASME standards.

Model RRU134
Large 1-½ HP open drive compressor, ½-inch lines, two-point vapor
extraction and oversized air-cooled condenser speed recovery on smaller
size chillers. Purging and switching from liquid to vapor recovery only
involves turning 3-way valves-no switching of hoses is necessary.
Capacity with R-134a is 55 lb/min liquid, 1.34 lb/min vapor.
