Refrigerant Recovery Units

Although Daikin 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.

Daikin 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 AHRI certified.

The storage tank is designed, constructed and stamped in accordance with ASME standards.
