Thermal Vacuum Testing

Dayton T. Brown, Inc. can perform Thermal Vacuum Testing, which simulates environmental conditions in space, in order to determine whether or not a test item is acceptable for space flight.

Our test chamber meets the following criteria:

  • A 4 ft. (dia.) x 6 ft. chamber with a working plate size of 19 in. x 27 in.
  • Ability to simulate space altitudes of 330,000 ft. or higher
  • Capable of reaching 1 x 10-5 Torr of vacuum – while simultaneously cycling the temperature to extreme highs and lows through a copper heat/chill conductive plate

We use the chill plate method to heat and cool test items in the chamber. This method uses a cooling fluid though the plate, such as liquid nitrogen, to lower the temperature, as well as built-in heaters to raise the temperature of the test item in a high vacuum environment.
