“flapper” is an innovative approach to thermal shock which can dramatically improve the space crowded situation of many testing laboratories and increase user flexibility.

The specimen is fixed in its position and the chamber is connected alternatively to hot and cold chambers (by “flaps”). This technical solution creates the possibility of the unit is capable of performing as a standard thermal shock chamber and also gives the possibility to perform ESS tests and conventional thermal cycles.

This style eliminates the problem of having to worry about cables that may need to “travel” with your test items. Since the unit under test stays in place it is easy to connect any wiring or sensors necessary to verify test results. The number of cycles before defrosting is considerably increased thanks to a pressure compensation system (bellows connected to both cold and hot rooms).

Additional feature

Further to the traditional thermal shock, the chamber can be used for some environmental stress screening and temperature profiles with a dedicated S W.
