Energy-saving refrigeration technology

Main Advantages and Characteristics:

Anti-clogging: Ensures heat transfer temperature difference ≤3°C in liquid-liquid heat exchange to avoid crystal scaling.

Refrigerant Direct Cooling: Saves about 50% energy compared to ethylene glycol refrigeration via phase change heat transfer.
