Ultra-low temperature bearing cooling equipment is also called ultra-low temperature freezer. Its working principle is to rely on the working operation of compressor, condenser, capillary, evaporator and refrigerant for refrigeration, providing low-temperature refrigeration and constant temperature working environment. Ultra-low temperature bearing cooling equipment can provide a deep-low temperature working environment of -10 ~ -160°C, and is used for testing, storage, and cold treatment of items in low-temperature and constant-temperature environments.

Ultra-low temperature bearing cooling equipment is mainly composed of low-temperature compressor units, condensers, condensation evaporators, oil separators, evaporators, insulation boxes, Siemens PLC control systems and other components. Heating technology, temperature control technology and refrigeration technology are used to carry out program-controlled heating, cooling, constant temperature and other work controls to carry out low-temperature cold treatment of materials. Ultra-low temperature bearing cooling equipment uses refrigerant as the medium, and through the work of the compressor, provides a low-temperature cold source to programmatically cool the industrial refrigerator box to the required low temperature environment of -90°C, -120°C or -160°C, and then Heat exchange cold treatment, testing, processing or storage of materials.

The main function of ultra-low temperature bearing cooling equipment is to transform a large amount of residual austenite in metal into martensite, which can reduce martensite lattice distortion and microscopic stress, and the fine dispersed carbides can reduce the plastic deformation of the material during plastic deformation. Impedes dislocation movement, thereby achieving better cooling effect. It can be used for frozen assembly of industrial bearings, copper sleeves, molds, gearboxes, gears, precision parts, etc. It can be used to eliminate the residual internal stress of metallic materials and non-metallic materials, and improve the strength, hardness, size and shape accuracy of steel parts. The stability can exponentially extend the service life of tools, molds and rollers, and can also improve the conductivity of copper electrodes.
