Model

The Liebert MC features an aluminum microchannel coil with a variable speed fan for each coil section. Constructed with an aluminum cabinet, the Liebert MC is a low-profile,
direct-drive, propeller fan-type unit suitable for mounting outdoors. It provides for the heat rejection of either one or two separate refrigeration circuits, matching heat rejection
capacity varying with the outdoor ambient temperatures and with each corresponding compressor’s heat rejection requirements. The unit is quiet and corrosion resistant. Copper
pipe connections are provided for brazing of copper field piping. Connections are located next to the electrical panel. All electrical connections and controls are enclosed in an
integral weatherproof section of the condenser.
