Product Details


Composed of a compressor, condenser, evaporator, filter drier, expansion throttling valve of the five most series, note the amount of refrigerant inside (refrigerant), the electrical appliances (including controller) according to the requirement of the environment and control the operation of the compressor to achieve the purpose of heat transfer and refrigeration.

Mainly used in industrial cold treatment, the uniform, fine and dispersed carbides produced on the metal structure matrix structure are precipitated. The appearance of such carbides will result in a significant increase in the wear resistance and friction properties of the metal, an increase in hardness, and will directly increase the life of the wear parts. The ideal product to replace liquid nitrogen.
