Name NSN Details  
Heating Unit,steam-Water 4520-01-502-9960 A unit which supplies hot water at an established temperature through a pipe system by means of a heat exchanger, mixing valve, and control valve. Cold water and steam are introduced into the heat exchanger, creating hot water, which, in turn, is mixed again with the cold water in the blending valve to generate a flow of hot water at a preset temperature.
