The series air cooled screw type chiller cooling capacity from 85KW to 1550KW. This series units integrates the characteristics of many other products, using imported semi-closed screw compressors,supplemented by high-efficiency heat exchangers and adopts microcomputer controllers, which makes the unit compact, reasonable layout, convenient to use and maintain. The user just need simply connect the pipeline of the water system and the required power supply,then can put into operation.
This series of chillers is widely used: it can provide process chilled water for industrial and mining enterprises such as textile, chemical and petroleum. The manufacturing technology of this product is mature and stable and reliable.
Features of chiller:
1. Employing original double/single SCREW compressor, compressor may according loading auto-adjust, add level sensor for prevent compressor low-loading to luck-oil, extent use life
2. Employing all-new imported high class component
3. Employing two sets of compressor which can be used jointly or independent
4. Switch control, easy operation and maintenance
5. The weld of brass pipe is non-oxidization
6. Condenser and Evaporator both to conform GB150, GB151, TB/T4750-2003, operation safe
1 Compressor reverse protective
2 Freeze protector protective
3 Refrigerant safety valve
5 High-pressure gauge and Low-pressure gauge
6 Power phase failure protector
7 Coil over-heat protector
8 Temperature auto-switch
9 Refrigerant shortage protective
