A Thermal Control System Pump Package Assembly for the International Space Station

The ITCS pump package assembly (PPA) is utilized in the Internal Thermal Control System (ITCS) of the International Space Station (ISS). The PPA circulates coolant throughout the ITCS system and provides for coolant expansion and contraction due to thermal excursion. The PPA is designed to operate in the International Space Station laboratory, habitat, and node II modules to circulate coolant for electronics and avionics cooling, experimental rack heat loads, and critical life support equipment.
