Ultra Low-Temperature Freezers are pieces of equipment that are used for the storage of drugs, tissue samples, enzymes & other biological products. The ULT refrigeration system consists of a compressor, an evaporator, a condenser, an expansion valve, and interconnecting tubing. In Ultra-low temperature freezers, the circulation of the cooling air is forced by an engine-driven fan, and the expansion of the refrigerant fluids is obtained by capillary tubes. The steel plate exchangers with coil perform evaporation and the coil in the cabinet eliminates the efficiency issue in the heat exchange of freezers with the coil in the insulation cavity.
