Technical specifications:

Prefabricated Cold room, walk-in, mono block, supplied with all
necessary mechanical and electrical fittings and equipment for quick and
easy installation in the field.

The unit is designed to operate from a mains supply of 400V/3/50Hz+N+T
+/-10% with a dual refrigeration unit, each refrigeration unit is sized
to give 100% stand-by capacity designed to operate at +2°C to +8°C in a
maximum ambient of 43°C. Units operating from a mains supply of
220V/3/60Hz +/-10% are available as option, please confirm the power
rating during the time of ordering for this option.
