MG-20ARC

The MG-20ARC splits the 18.5-ton refrigeration package from its condenser: the compressor, pump and reservoir stay indoors in one cabinet, and the 2-fan condensing unit mounts outdoors on its own line set. The process pump moves 48 GPM at 43 PSI through a centrifugal head. Process connections are 2" NPT. The 65-gallon reservoir carries a standard automatic make-up valve. Running the condenser outdoors keeps compressor and fan noise out of the process area and frees floor space, at the cost of a refrigerant line set that has to be sized and vertical-lift-checked for the actual indoor-to-outdoor run — send us that distance before ordering. Two compressor circuits share the load, so the unit keeps running at reduced capacity if one circuit needs service instead of leaving the process with no cooling at all. Charged with R-454B.
