Abstract
Cryogenics have been derived from the Greek word 'KRUOS' (frost) and 'GENICS' meaning to produce very low temperatures. A Cryogenic processor is unit designed to reach ultra-low temperatures 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. The development of programmable microprocessor controls allowed the machines to follow temperature profiles that greatly increased the effectiveness of the process.
The treatment process of cryogenic processors was previously done manually by immersing the object in liquid nitrogen. In Modern cryogenic processors, programmable microprocessor measure changes in temperature and adjust the input of liquid nitrogen accordingly.
The general processing cycle for modern cryogenic processors occurs within a three day time window. Some processors are capable of providing both the negative and positive extreme temperatures. The optimal bottom temperatures for objects, as well as the hold times involved, are determined utilizing a number of different research methods and backed by experience and analysis to determine what works the best for a given product.
Cryogenic processors are radically changing the way that cryogenics used to be done. As the technology sector improves, cryogenic processors will only get better as they benefit from new computer systems. Ongoing research in the future will also improve their temperature treatment profiles.
