The screw chiller is named as the screw chiller because of its key component-the compressor uses the screw type. The unit is a gas refrigerant from the evaporator. After the compressor is adiabatic-ally compressed, it becomes a high temperature and high pressure state. The compressed gas refrigerant is cooled and condensed in the condenser under constant pressure. After the condensation, it changes to a liquid refrigerant, which is then expanded to a low pressure by a throttle valve and becomes a gas-liquid mixture. Among them, the liquid refrigerant at low temperature and low pressure absorbs the heat of the material to be cooled in the evaporator and becomes a gaseous refrigerant again. Gaseous refrigerant re-enters the compressor through the pipeline and begins a new cycle. These are the four processes of the refrigeration cycle and the main working principle of the screw chiller.

Compressor high and low pressure protection, internal overheating protection.

◆ Low water flow alarm device; low water temperature anti-icing alarm

◆ Adopt compressors imported from Europe, America and Japan

◆ Welding joints of refrigeration system adopt oxygen-free welding method to reduce oxides,Smooth surface

◆ Use stainless steel plate type, coil type, shell tube type, fin type

◆ Heat Exchanger

◆ RS485 communication function for automatic management (optional)

◆ Electrical appliances use OMRON. FUJI. TE. LG. MOELLER. SCHNEIDER
