In petroleum refining, petrochemical industry, organic synthesis, chemical products and other industrial production, refrigeration technology must be applied to control the reaction temperature during processes such as liquefaction, condensation, solidification, separation, refining, crystallization, concentration, and purification.

The chemical industry is mainly used for the cooling and cooling of chemical reaction kettles, and takes away the ordinary heat generated by chemical reactions in time to reach the purpose of cooling (cooling), in order to improve product quality. If the cold water (wind) provided by the refrigerator is used for cooling, not only the product quality can be greatly improved, but also the consumption efficiency can be improved. The pharmaceutical industry is mainly used to control the temperature and humidity of the workshop and to take out the heat of reaction during the process of consuming the drug substance.

Refrigerators in the industry are basically composed of components such as evaporators, single-stage compressors, oil separators, condensers, and liquid storage tanks. LNEYA’s freezer has exclusive technology, the temperature range is -5 ℃ ~ -150 ℃, which can meet different temperatures. This cooler uses international brand Carrier compressor, adopts automatic cascade refrigeration mode and mixed refrigerant, direct cooling ultra-low temperature freezer, single compressor automatic cascade refrigeration technology can freeze to minus 120 ° C in 3 minutes. Before delivery to customers, the production workshop provides machine installation and system testing. Users only need to complete the installation of refrigerant and cooling water.

The working principle of LNEYA low temperature chiller is as follows:
