Large Walk-in Vacuum Plant and System LEGTHV

  • Large Walk-in Vacuum Plant and System LEGTHV for simultaneous testing of temperature and low-pressure altitude conditions. Two common applications are:

    • Testing of avionics or other aerospace equipment to simulate actual conditions it might experience.
    • Simulation of high-altitude conditions like might be found in mountainous regions.

    NOTE: Altitude test chambers are custom systems, and differing requirements may significantly change the cost and utility requirements.

  • Features

    • Temperature range from -160℃, -150℃,-120℃, -100℃, -80℃,-70℃, -60℃, -40℃, -20℃, 0℃~+150℃, 200℃, 250℃, 300℃,400℃, 500℃, 600℃, 700℃, 800℃, 900℃,1000℃
