Cascade phase change cooling systems (Dual compressors)

Each gas has a boiling point / condensation different, so using different properties of various gases can be obtained at very low temperatures using a set (2 or more) of compressors in cascade to achieve higher performance than regular cooling Phase Change in single compressor.

In particular, the Cascade cooling (dual compressor) is to condense a gas different from the first stage, then let it evaporate at a lower temperature and obviously to work properly the gas must have the appropriate features. The concept on which the operation of the cooling cascade consists of a condensing gas at the temperature of the evaporator of the first stage (about -40 ° C) and then a later evaporated at a temperature of -100 ° C and beyond.

So a first compressor can be loaded with a gas type R404 or R402 or 507 and reach temperatures around - 40 ° C. The compressor is next loaded with gas instead of low-temperature evaporation which allows to reach temperatures above -100 ° C, coveted by both builders Phase Change, whether users (extreme overclocker) in search of ever lower temperatures to obtain new records.

Thanks to pressure regulators, always present in cascade systems, you can adjust the temperature and thus have a big advantage especially if one has to do with CPU problems with bugs or cold-cold-boot. The principle of the compressor cascade is applicable with any gas, but only some have characteristics suitable to reach these temperatures.

DimasTech Systems SNC Phase Change Cascade offers both standard and customized according to customer requests. For special needs and it can be expected DimasTech SNC implementation of special projects. The applications of cascade systems are not limited to the use for extreme overclocking but can also find great feedback on areas of laboratory, medical and food products.

Vantaggi: Low working temperature compared to Phase Change or Dry Ice Cooling, Simply Use.

Disadvantages: Possibilità of condensation, cost, energy, no daily use.
