Heat flux cages that precisely replicate the
temperature extremes of space

Spacecraft are subjected to huge temperature fluctuations as they fly through sunlight and shadow. Dynavac’s heat flux cages are custom designed for your mission and subject your spacecraft to full temperature swings in a full vacuum environment. We cover spacecraft of all sizes—even as large as the Artemis One manned space capsule.

Heat flux cage highlights

  • Thermal enclosures radiate infrared heat to selected portions of spacecraft
  • Cage supports an array of heat lamps
  • Independently controlled temperature zones
  • Temperature, duty cycle, and temperature ramp rate all configurable
  • Cage configuration in any size and geometry is available to suit your spacecraft
  • Heat flux cage works within your existing vacuum chamber or a Dynavac chamber
