An aerospace industry customer required a high vacuum system to test and validate the integrity of their imaging system components under extreme pressure and temperature conditions.

We configured a system using our standard 36" diameter by 40" deep vacuum chamber utilizing a cast aluminum platen with an embedded LN2 manifold and electrical heating elements to achieve the target temperature ranges. A cylindrical thermal shroud with LN2 cooling on a separate cooling zone was also included.  This FST system also included as standard or ISO 160, 6" diameter door viewport with internal LED lighting. Vacuum pumping system included a dry roughing pump and upgraded high pumping speed cryopump high vacuum pump package.

 System is fully integrated on a ruggedized mobile frame and testing is controlled entirely using our versatile HVC-3500 Thermal Vacuum Controller.


  • System Platform: 36" DIA x 40" L cylindrical horizontal vacuum chamber made of 304 stainless steel and a #4 grain polish on the inside for vacuum to 10^-7 torr
  • Platen: Internal  cast aluminum platen, approximately 24" W x 38" L with internal thermal channeling and mounting points laid out on a 4” grid
  • Shroud: Internal shroud – 304 SS pillow-plated shroud, offset 1” from chamber wall
  • Process Controller: HVC-3500 Thermal Vacuum Controller with 7” color touch screen, 2 analog inputs, 10 digital inputs, and 6 relay outputs
  • Thermal Zones: Zone 1 Platen includes LN2 and electrical heat  for heating and cooling, Zone 2 includes LN2 cooling of shroud.
  • Pump package: Dry roughing pump and cryopump high vacuum pump
  • System Enclosure: Ruggedized frame w/heavy-duty casters and electrical panel enclosure
