Thermal Vacuum Test

Space Simulation

Testing in a thermal vacuum chamber is a requirement for compliance with various regulatory standards in the aerospace and defense industries. The thermal vacuum test has been used since the beginning of the US space program to reduce risk and prepare for extreme temperatures in orbit.

Thermal vacuum testing services of EUROLAB have been used for preparation for both manned and unmanned spaceflight. We work directly with government agencies and relevant contractors to develop and maintain accurate and controlled conditions suitable for thermal testing.

High vacuum

Having years of experience in testing components, subassemblies and systems used in aviation, EUROLAB has developed a comprehensive practical know-how to use high-value equipment, protect it while in our laboratories and ensure that tests run perfectly every time, eliminate unnecessary tests.

EUROLAB operates several rooms specially designed to meet the stringent demands of space simulation. High thermal vacuum chambers and their immediate surroundings are controlled environments in which some of our rooms are classified as Class 10000 clean rooms. Chambers simulate high altitude / space environments with the main parameters of:

• High Vacuum: 1 x 10-7 Torr (2 x 10-9 psi)
• Cold Area: -175 ° C (-285 ° F)
• Solar Radiation (IR): up to + 150

Room sizes range from 15 ′ x 25 ′ units to an economical 12 inch diameter for quick testing of small components. Temperatures range from -175 ° C to + 375 ° C. In our larger thermal vacuum chambers, LN2 full cover is used for cooling and IR heating. Instrumentation includes up to 300 mixed channels; voltage, thermal pair, RTD, strain, resistance and current. TQCM, CQCM and RGA analysis are available. Pressure ranges are available below 1 x 10-7 Torr (2 x 10-9 psi). Pumping systems include coarse (oil-free or molecular trap) and high vacuum (turbo molecular or cryogenic).

EUROLAB high vacuum space simulation facilities primarily perform tests on sophisticated solar panels, antennas and satellite components, while the high vacuum / temperature environment prevents heat dissipation and discovers errors prior to field use, exaggerating the reaction of gases trapped in any product.
