The refrigeration plant was built by J & E Hall Ltd. of Dartford, England. The company is still in business today.
Each compressor set consisted of two duplex compressors using Co2 as the refrigerant and each set was situated in the reciprocating engine room on the port side in front of the turbine engine room on the tank top level. The shell & tube condensers used sea water pumps built with brass valves. The Co2 would now cool brine taken from the brine tank on the lower deck level and this chilled liquid would be pumped to the various cold spaces. The CO2 returning to the compressors to be used again.
The main cold stores were on the lower deck towards the stern and there was a refrigerated cargo hold immediately below on the orlop deck. The cooling in these rooms was achieved using galvanised pipes formed into a serpentine shape and fitted to the walls or ceiling. The air around the pipes would be cooled and would drift downwards to be replaced by new, warmer air.
There were other refrigerated products such as the drinking water: bars a small ice making machine and an ice cream machine.
