Ultra low temperature series

-50℃~-135℃


Ultra-low temperature cascade cryogenic unit

Multi-stage refrigeration cycle: Composed of two or more independent refrigeration cycles, a high-temperature stage and a low-temperature stage. The high-temperature refrigeration system uses a medium-temperature refrigerant to first transfer heat to the low-temperature system; the low-temperature refrigeration system uses a low-temperature refrigerant to further lower the temperature to an ultra-low temperature range. For example, common high-temperature refrigerants include R404A and R22, while common low-temperature refrigerants include R23 and R14.
