The temperature control range of REFTEK ultra-low temperature freezer is -150 ℃ to -10 ℃. The refrigeration system adopts single compressor refrigeration, two-stage cascade refrigeration and other methods. And it is equipped with multiple protection functions to ensure the safe operation of the equipment. By cooling the unit itself, liquid low-temperature refrigerant is sent to the end evaporator for cooling, creating a low-temperature environment that meets the process requirements.
Adopting single machine self stacking technology, occupying a small space;
Constant temperature range:
-60℃±1℃
-80℃±1℃
-120℃±1℃
1、 Industrial applications:
Used in industrial cold treatment, it can improve the performance of various materials, mainly reflected in the application of cold work mold steel, high-speed steel, bearing steel, cold work molds and mold accessories. The REFTEK cryogenic treatment box can significantly improve the hardness and strength, dimensional accuracy, wear resistance, impact toughness of workpieces, improve stress distribution inside workpieces, enhance fatigue strength, and improve corrosion resistance.
The so-called cryogenic treatment is to continue the cooling process of quenched metal materials to a temperature far below room temperature, promoting the further transformation of residual austenite existing after conventional heat treatment into martensite that can harden and strengthen the steel, thereby improving the properties of the metal material. After cryogenic treatment, the wear resistance, toughness, and dimensional stability of metal tools can be significantly improved, doubling the service life of the workpiece.
Mainly used for cold shrinkage of copper sleeves, bearings, etc., widely used in precision mechanical assembly.
It also has a wide range of applications in the field of ultra-low temperature testing for large equipment (automobiles, large construction machinery, aircraft components, aerospace equipment components, military equipment components).
It can also be applied to the modification of cutting tools, measuring tools, molds, and precision parts, such as oil nozzles for oil pumps, turbine shafts for engines, rollers, valves, gears, springs, and other workpieces.
2、 Biological applications
Applied in biological cold treatment, mainly reflected in frozen stem cells, blood, plasma, and drugs, it can quickly cool and freeze plasma and blood. The product has a wide range of application markets and prospects in the field of biochemistry, and its wide temperature control range is suitable for diverse usage environments and needs.
