What is Low Temperature Chiller
As the name suggests, low-temperature chillers are chillers whose outlet water temperature is lower or much lower than that of ordinary chillers. Ordinary chillers have an outlet temperature ranging from 3°C to 35°C, while low-temperature chillers can achieve temperatures from -5°C to -40°C. Model selection is matched according to customer requirements. Our DMG low-temperature chillers are widely used in chemical reaction kettles, rubber and other fields. The circulating medium changes from water to ethylene glycol aqueous solution, and R404 low-temperature refrigerant is selected as the refrigerant.
DMG Low Temperature Chiller
This unit is wide-range low temperature chiller, works from -30℃ up to 20℃. Equipped with Invotech low temp scroll compressor and aluminum brass evaporator, good compatibility with glycol solution. Integral design with tank & pump, external bypass valve guarantees stable flow and anti-freezing protection.
