Water Cooled Screw Chillers

  1. The water-cooled screw chiller adopts the most advanced 5:6 high-efficiency semi-hermetic screw compressor;

2. These series have 35 models, and the cooling capacity range: 183-2300kW(50~630Tons).

3. Microcomputer touch screen control system, convenient operation interface and timely feedback of various maintenance information.

4. Multi-stage or stepless capacity control;

5. A variety of safety protection measures ensure the unit in normal operation for long time. Provide emergency stop and power plug for maintenance tools use.

6. High efficiency, energy-saving, stable operation and durability, suitable for central air conditioning in various places.

7. The chiller can also be equipped with a heat recovery device according to the needs of users to recycle the “waste heat” dissipated into the atmosphere and provide users with hot water at 50~60℃, making it more suitable for hotels, dormitories. While providing chilled water for factory production, it can also make hot water for tourists and workers.

8. All units have passed the national safety inspection system test before leaving the factory to ensure that the unit performance meets national standards.

Note: The above data are gotten under the following testing conditions:
1. Nominal cooling capacity:inlet/outlet chilled water 12/7℃, condenser inlet/outlet water temp. 30/35℃, fouling factor 0.088 m2 ℃/kW;
2. When condenser inlet/outlet water temp. is 32/37℃, chilled water temperaturer has no change, cooling temperature is 0.975 of rated cooling capacity.
3. Chilled water temperature range 5~15℃(R407C),  5~20℃(R134a);
4. Condenser water temperature: 20~40℃(R407C), 25~45℃(R134a).
5. The specifications may have some changes due to product improvement without notice.

1. Chillers are widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial refrigeration processes

2. large shopping malls, hotels, factories, hospitals and other central air-conditioning projects
