Recovery machine

Options
Hvacr experts ! What components inside the refrigerant recovery machine? I know it’s gonna be compressor condenser and what else? Why recovery machine can recovery liquid refrigerant? Won’t slugging the compressor? I think should be metering inside the recovery machine right? And also recovery machine got condenser inside so outlets should come out with liquid form refrigerant right? Anyone please !!!

    Probably just an accumulator on the low side to hold the liquid.

    The coil on a recovery unit it is of course a condenser , the outlet is liquid . Most are able to pump liquid being there more like a pump then a compressor in a closed refregerant system . If i remember most of the first recovery reclaim, machines did have suction line accumulators and a whole bunch of bs a lot of the early reclaimer where slow as dirt and where pos and huge heavy and just about had to be Hercules to rope them up to a roof . Now a days there tiny little turds and reclaim quite fast . I’m close to picking a new appion g5 ,one of the Hvac contractors I help do change outs w has one and the thing is like greased lighting ,my tool bucket weight at least 4 x as much . Peace and good luck clammy

    Clammy is describing my first recovery machine. "Katy"...K-3330-TB from Jameskamm of Ohio.

    Described as "lightweight" although a wheel kit was an option. Very heavy.

    Had a 5 Lb charging cylinder on board, for recovery, that was handy for small jobs.

    Max condensing pressure of 350 PSI. Would pump vapor only.

    From the early 90's when we were all convinced that the "Freon Police" would be around every corner.

    This is available at a bargain price as I do not have a boat. ;)

    Now have a Appion G5 Twin which weighs less than my old 1984 vacuum pump.
