Espec Damper Type Thermal Shock Chamber


The Espec thermal shock chambers from the TSA series are characterised by their unique stationary test compartment. The TSA works with an automatic air regulator that takes the air from the warm or cold chamber to the test chamber. Contrary to most shock chambers that use a lift system, the TSA can carry out shock tests on products without the possibility of mechanical stresses occurring.
The TSA series is available in a two-zone and a three-zone configuration. The three-zone configuration can expose the product to cold and hot temperatures during a test cycle, but also to the ambient temperature. This is a requirement for some thermal shock tests.
