1. The cooling capacity is based on: chilled water inlet and outlet water temperature 1°C/-5°C; cooling air inlet and outlet temperature 40°C/45°C. 2. Working range: frozen water temperature range -5 °C ~ 30 °C; It is recommended to use it when the ambient temperature is not higher than 35°C; 3. When the water temperature is minus 5 degrees, add 25% ethylene glycol antifreeze.
