Thermal Altitude Testing Chambers
Common Features:
- Vacuum chambers are constructed from 304 stainless steel and range in size from Ø45" x 50" long up to Ø52" x 72" long.
- Single or double elastomer sealed vacuum chamber doors are available enabling easy access to the chamber interior.
- A height adjustable and mobile cradle bases four point frame supports the environmental chamber and simplifies lab installation requirements.
- Fluid circulation thermally controlled Aluminum tooling plates range in size from 36" x 42" up to 42" x 68".
- A space simulation temperature controlled thermal shroud uses fluid circulation to achieve temperatures ranging from -60°C to +120°C.
- Solar selective coatings within the space simulation shroud enable excess radiation to be captured and effectively drawn away from any test samples mounted on the tooling plate.
- Efficient isolation between the thermal simulation shroud and the high vacuum chamber assist in control stability and temperature ramp rates.
- A variety of mechanical roughing pumps are available with a diverse range of volumetric flow rates depending on the vacuum pump down time requirements.
- Single or dual high vacuum 3000 l/s cryogenic pumping configurations are available.
- Full range vacuum gauging ties into system automation programs to provide safety set points and system monitoring.
- Fully automated PLC system control allows automated or manual vacuum pump down, venting and cryo pump regeneration cycles through a PC interface in an independent electrical control rack.
Space Simulation Products
The altitude environmental test chambers shown throughout the images on this page were designed for research and development involving satellite testing, space science and engineering.
Our space simulation high vacuum chambers combine temperature control and altitude simulation to test components and subassemblies for a variety of industries.
The vacuum chamber is fitted with a temperature controlled fluid circulation shroud assembly to simulate the thermal absorptivity of an outer space environment.
The thermal shroud is formed to match the shape of the vacuum chamber above a component mounting platen.
The mounting platen has an array of tapped holes for clamping down test components to improve thermal conductivity.
Solar absorption end plates are located to either end of the thermal shroud reducing unwanted radiant energy transfer.
All inside surfaces of the thermal shroud are coated with a vacuum compatible, high absorptivity, low thermal emittance solar selective finish to account for component test radiation emissions.
Vacuum base pressure in our cryo pumped space simulation chambers are less than 9.0E-8 Torr with elastomer sealed vacuum flanges.
To enhance temperature process stability the shroud assembly is thermally isolated from the surrounding vacuum chamber walls.
The temperature is controlled on the thermal shroud assembly by passing fluid through a tubing network that has been welded or brazed to the respective sections of the shroud.
Conventional fluid circulation systems will expose the shroud to a thermal cycle ranging from -60°C to +120°C without use of liquid nitrogen. However with minimal modification the thermal shroud may be used with a liquid nitrogen system to achieve cryogenic temperatures.
