Thermal Vacuum Chamber (TVAC)

Ultra-high vacuum and deep thermal cycling system designed for space components, satellite subsystems, and advanced optical payloads.

Thermal Vacuum Chamber (TVAC)

Engineered for Mission-Critical Scientific & Industrial Research

In space, equipment is subjected to ultra-high vacuum where convective cooling is completely absent, heat transfers exclusively by radiation/conduction, and materials undergo outgassing. Subsystems alternate between extreme solar radiation and deep cryogenic cold. Biostag TVAC systems combine precision electropolished stainless steel vacuum vessels, multi-stage turbo-molecular / cryogenic high-vacuum pumps, optical shrouds with LN₂ / electrical heating circuits, and comprehensive multi-channel telemetry.

Core Technological Highlights

  • High Vacuum: Down to 10⁻⁶ mbar
  • Thermal Shroud: -180°C to +150°C
  • Precision SCADA & Data Logging
