Thermal Vacuum Chamber (TVC) – Indigenization by Jetsys Defence

Jetsys Defence designs and manufactures Thermal Vacuum Chambers that accurately simulate space conditions—deep-vacuum and extreme thermal cycling—for qualification, screening and R&D. Our TVC systems support satellite subsystems, payloads, optics and electronics where a space simulation vacuum chamber and thermal vacuum testing chamber are essential.

What is a Thermal Vacuum Chamber?

A Thermal Vacuum Chamber (TVC) creates a high-vacuum environment while cycling temperatures to replicate on-orbit conditions. By combining cryogenic shrouds, thermal platens, and precise control, a TVC validates flight hardware for survivability, performance, and outgassing compliance—exactly what a space simulation vacuum chamber or thermal vacuum testing chamber must achieve.

Key Features of Jetsys Defence TVC

  • High Vacuum Performance Pumping architecture engineered to achieve high-vacuum levels suitable for space simulation and bake-out workflows.
  • Wide Thermal Envelope Cryo-shrouds and heated platens provide deep-cold to high-temperature profiles with programmable ramps and soaks.
  • Uniform Thermal Radiation Multi-zone shrouds and emissivity-controlled liners ensure stable, repeatable heat flux to the test article.
  • Flexible Chamber Geometry Available in cylindrical or rectangular formats, from benchtop to field-constructed sizes with payload carts and vibration-safe mounts.
  • Clean, Low-Outgassing Build UHV-compatible seals, surface finishes, and vacuum-rated cabling protect optics and sensitive electronics.
  • Data & Controls Integrated HMI/SCADA, recipe control, alarms, historian logs, and DAQ for thermocouples, RTDs and vacuum pressure.
  • Feedthrough-Rich Interfaces Electrical, fiber-optic, RF and fluid feedthroughs with configurable panels and blanking flanges.
  • Serviceability & AMC Indigenized sub-assemblies, local spares and preventive maintenance plans ensure high uptime and lower lifecycle cost.

Benefits of Thermal Vacuum Chamber (TVC)

  • Flight-Like Confidence Validates thermal balance, survivability and functional performance before spacecraft integration.
  • Lower Program Risk Identifies thermal design gaps, vacuum leaks, contamination risks and component drift early in the cycle.
  • Repeatability at Scale Recipe-driven cycles, high sensor density and automation provide consistent, auditable results.
  • Cost & Lead-Time Advantage Indigenized build, local support and rapid spare availability reduce total cost of ownership.
  • Clean, Safe Operations Low-outgassing interiors, efficient pumping and fume-safe heating ensure a clean test environment.
