Expose your hardware to the thermal and vacuum conditions it will face in orbit. Thermal cycling, TVAC, and thermal balance verified across your full operating range.
Thermal cycling and humidity testing operational on enveon climate chambers (180 / 600 / 1000 L).
TVAC chamber scheduling open — early-2026 slots being allocated.
From atmospheric thermal cycling on operational chambers to full thermal-vacuum campaigns — tailored to your mission environment.
Repeated exposure to the temperature extremes your hardware will see in orbit. Functional checks performed at hot and cold dwells. Available on operational climate chambers from 180 L to 1000 L volume.
Combined thermal and vacuum exposure simulating the on-orbit environment. Used for qualification and acceptance testing where convective cooling must be eliminated. CubeSat-sized chamber under commissioning — slots open.
Steady-state thermal verification under representative orbital flux conditions. Confirms thermal model predictions and validates thermal control hardware before committing to flight configuration.
Size-based setups keep chamber volume matched to the hardware. no oversized chambers, no wasted volume, and therefore no unnecessary thermal lag.
Thermal cycling is fully operational on enveon’s existing chambers — already testing electronics, sensors, and full CubeSat assemblies on a weekly basis.
TVAC is the latest addition. The chamber is sized for CubeSat-class hardware, with vacuum and thermal control matched to common orbital regimes (LEO SSO).
Both setups support functional testing during cycling — so you can detect anomalies as they happen, not after final delivery.
Applicable test levels and margins are confirmed in the test plan — directional standards below
European Cooperation for Space Standardization — testing standards including thermal vacuum, thermal cycling, and qualification/acceptance levels.
U.S. military standard for environmental test requirements for launch and space vehicles. Reference for thermal margins.
NASA General Environmental Verification Standard — used as reference for CubeSat-class thermal and qualification levels.
A non-exhaustive list of scenarios where TVAC or thermal cycling is the right move.
End-to-end thermal cycling of fully integrated 1U–16U platforms before flight delivery.
TVAC of telescopes, cameras, and IR sensors where outgassing or thermal distortion are flight-critical.
Thermal stress screening of power distribution units, OBC, and avionics boards.
Thermal cycling of antenna mechanisms, RF chains, and deployment hardware.
TVAC rarely sits alone in a qualification campaign — these are the test types most often paired with it.
Survive launch loads before you survive orbit.
Electromagnetic compatibility for the integration environment.
Verify behaviour after thermal exposure, not just structural integrity.
Bundle TVAC, vibration, and EMC into a single coordinated campaign.
