Custom high vacuum space simulation system for aerospace components.
The customer required 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. A typical system with 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 a the more expensive chiller option.
