A 2-stage direct expansion system that can achieve cryogenic temperature of -70degC.

•   Small TD reduces frost build up in the heat exchanger
•   Smooth and continuous operation at the ultra-low temperature range.
•   Reliable and efficient production of high-quality frozen products.
•   Energy savings and operational efficiency far superior to those of a cascade refrigeration system for ultra-low temperature operations.
•   Wide range of freezers for your needs, from the compact 50kg/h freezer to a 40 metric ton/day rack freezer.
•   Operating temperature ranging from -20degC ~ -70degC.
