Cryogenic processor

A Cryogenic processor is a unit designed to reach ultra-low temperatures (usually around -300°F / -150°C) at a slow rate in order to prevent thermal shock to the components being treated. The first commercial unit was developed by Ed Busch in the late 1960s^[1]. The development of programmable microprocessor controls allowed the machines to follow temperature profiles that greatly increased the effectiveness of the process. Some manufacturers make cryoprocessors with home computers to define the temperature profile. The reliability of these computers in an industrial environment is greatly in doubt.
