Liquid to Liquid thermal shock chambers

Climatic chambers for “liquid-to-liquid” thermal shock tests are used to test electronic components with strong shocks by passing them suddenly and repeatedly from a tank with hot liquid to one with cold liquid. The liquid used, whose physical state remains unchanged within the chamber temperature range, subjects the DUT (Device Under Test) to a strong shock that tests its resistance. The range of climatic chambers for “liquid-to-liquid” thermal shock tests includes two models: CSTL (12 and 20 l). Two powerful compressors are cascaded and provide fast, reliable, temperature cooling performance. The basket movement is electrically operated and has a transition time from one chamber to the other of less than 10 seconds. The chamber is equipped with a “bellows” used for pressure compensation during test operations. This avoids overpressure inside the chamber which could force open the door and cause fluoride leaks.
