Note: Water Cooled Chillers can be customized explosion-proof.

The water-cooled chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat in the water. After the water is cooled, the heat is   transferred to the shell-and-tube condenser through the compressor. After the water absorbs heat, the heat is taken out to the external cooling tower   through the water pipe for heat dissipation.

1.Temperature control range: – 120 ℃~350 ℃; Single fluid water-cooled chiller is used for rapid cooling and heating at night, and is widely used in petrochemical, medical, pharmaceutical, biochemical, freeze-drying, military and other scientific and technological industries. 2. Famous brand semi-closed piston compressor, semi-closed bipolar piston compressor, semi-hermetic screw compressor, main brand are BOCK. Bitzer, Copeland, Handbell, fusheng; Plate heat exchanger, Small volume, High efficiency
3. Top imported cold controller; Generator cooling water circuit uses intermediate heat exchanger, improve system reliability and safety.
4. DANFOSS electronic expansion valve, high precision control;
5. Adopt Siemens PLC S7-200/300, LNEYA touch screen, automatic control, temperature curve display, temperature record U disk, fault alarm;
6. Offer machine installation and system test, users only need to finish the installation of refrigerant and cooling water.
