Vacuum Chamber Internal, front view

A leading aerospace university required a high vacuum space simulation chamber to be part of a system capable of achieving tested part temperatures ranging from 60 ˚C down to -40 ˚C with a temperature variation of ±3 ˚C, as well as a ramp rate of 1-3 ˚C per minute. 

Typical systems capable of this range of temperatures would require the integration of a high chiller. Chillers are closed loop systems that use a variety of fluids and are highly effective at very precise temperature control, but also require significant cost. We engineered a custom high vacuum space simulation system that utilized a direct injection  LN2 platen delivery system and electric heaters instead of the more expensive chiller option.
