T/V and C/V series vacuum test cabinets

Altitude simulation cabinets to simulate vacuum and high altitudes

Low or reduced air pressure is an important parameter in aviation and in the automotive sector. Low air pressure in combination with extreme climatic conditions can have an impact on the safety, function and performance of a product or individual components. Vacuum or altitude simulation cabinets are therefore used to reproducibly simulate the environmental conditions for e.g. aircraft components at flight altitudes of 10,000 to 15,000 m or for vehicle components travelling in the mountains at high altitudes. The CTS vacuum test cabinets enable tests to be carried out with controlled parameters of negative pressure, temperature and humidity. Due to the special design, combined vacuum/temperature tests are possible over the entire range of pressures and temperatures.
