Portable unit for simulation of freezes and refrigeration, has geometric form of flat faces consists of prefabricated insulating panels of variable thickness assembled together, cooling source obtained from expansion compressed air

摘要

The unit has geometric form of flat faces consists of prefabricated insulating panels of variable thickness, which are assembled with together, a cooling source, which is obtained from expansion of compressed gas. The unit also has programmable controller, a temperature probe, in which a controller acts on a cryogenic electro valve that regulates the expansion of the gas.
