Description of water cooled water chiller
1. This type of water cooling chiller are made of superior compressor, so it is exllcellent in quality, noiseless, economical and durable.
2. The evaportors are shell and tube types, which are of excellent performace.
3. The cooling capacity covers a range of 120-2002KW
4. It is compact-sized, with sufficent cooling capacity, and easy to clean.
5. All-round safety protection: phase reversion protection, phase lack protection, overload current protection, discharge sir temp. protection, low&high pressure protection , low temp. protection, water flow protection
6. Refrigerant is R407C,R22,but R410A,R134A also available
7. Rated cooling capacity base: chilled water inlet/outlet temp.17 °C /12V
cooling water    inlet/outlet temp. 30°C/35°C, fouling factor:0.088m2 · °C/KW.
8. Use with fan coil unit, Widely used in building air conditioning system, small and medium-sized office, workshop, restaurants, villas and other air conditioning environment
