General Description
MAGNUM units are all-electric, single-piece, refrigeration units with bottom air supply. The unit is
designed to cool and heat containers for shipboard or overland transit. The unit mounts in the front wall of
the container. Fork lift pockets are provided for installation and removal of the unit.
The frame and bulkhead panels are constructed of aluminum and are treated to resist corrosion. A
removable evaporator compartment door provides service access. All components except the evaporator
coil and electric heaters can be replaced from the front of the unit.
Each unit is equipped with an 18.3 m (60 ft.) power cable for operation on 460-380V/3 Ph/60-50 Hz
power. The unit power cable is stored below the control box in the condenser section.
Each unit is equipped with 460-380V/3 Ph/60-50 Hz electric motors. An automatic phase correction
system provides the proper electrical phase sequence for condenser fan, evaporator fan and compressor
operation.
