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
