Ultra-Low Temperature Cascade Refrigeration Unit Introduction
An Ultra-Low Temperature Cascade Refrigeration Unit is an industrial cooling system specifically designed to achieve extremely low temperatures, typically ranging from -60°C to -150°C or even lower. It overcomes the limitations of single-stage refrigeration by cascading two or more independent refrigeration cycles (stages), each utilizing a refrigerant suited to its specific temperature range, thereby achieving ultra-low temperatures efficiently and reliably.
Breaks the temperature limits of a single refrigerant through staged cooling
①High Operational Efficiency: Each refrigerant operates in its optimal temperature range, resulting in high overall system COP. ②Stable and Reliable: Optimized design ensures long-term, stable operation under extreme conditions. ③High Flexibility: Can be designed as two-stage or multi-stage cascade depending on the target temperature.
CO₂ Cascade Refrigeration Unit
A CO₂ cascade refrigeration unit is an environmentally friendly and efficient system that operates through two independent refrigeration cycles (high-stage and low-stage), where the low-stage cycle uses carbon dioxide (R744) as the refrigerant. This design cleverly leverages the excellent performance of CO₂ at low temperatures with the stability of other refrigerants at higher temperatures.
High COP at low temperatures
The comparison highlights that the core strength of CO₂ cascade units lies in their effective balance of environmental benefits, safety, and energy efficiency.
