he shock chamber is designed to expose test samples to thermal shocks. Accurate simulations in accordance with standards (including defense standards) are possible. The shock test in the device is carried out by means of an automatically controlled elevator moving between chambers at two extreme temperatures: high and low. The device is a horizontal chamber, i.e. the working chambers are located side by side.

The shock chamber makes it possible to test the resistance of parts and devices to rapid temperature changes (i.e. thermal shocks).

Test description:

The test aims to simulate the cyclic splashing of heated up elements with cold water.
Examples of test objects:
Engine cooling modules, lamps, solenoid valves, wiring/tubing bundles and others.
In addition, we provide glycol or oil circulation to the test objects, as well as electric cycles (if required).
