Apollo-era LM cabin heat exchanger, non-flight/developmental model, made by Hamilton Standard. Complete system consists of a motor assembly, cabin fan, and refrigeration package. Reverse also bears a Hamilton Standard manufacturer’s plate on the front, with “Heat Exchanger Cooling Regen,” imprinted on the time name line. A front panel also has labels for the incoming and outgoing tubes for water and cold glycol. This unit is a developmental variant of the LM coolant regenerative heat exchanger which provided for transfer of heat rejected from onboard electronic equipment and suit circuit regenerative heat exchanger. The unit was designed to recover waste heat from the astronauts and the electronic equipment and then transfer that recovered heat to coolant entering the cabin heat exchanger for warming of the LM cabin atmosphere. This proved a more efficient and lighter power than installing a separate heater on the spacecraft. This exchanger would have been mounted forward of the ascent engine cowling. System is housed in a heavy metal frame to an overall size of 20 x 28 x 13. In fine condition.
