Description

Screw water - cooled chiller 
Screw water-cooled chiller condenser cooling medium and the refrigerant are water chillers are widely used in various fields of central air conditioning, industrial cooling. 

1. Precise stable water temperature: As used for industrial cooling, Low temperature water which produced by warter-cooled chiller could send to the equipment and containers directly which need to be cooling. 
2. Y-depressurization start mode: Half a dense screw water chiller use Y-depressurization start mode. 
3. Capacity adjustment: Screw water-cooled chiller according to the use of Client load can automatically adjust load capacity. The standard chiller capacity adjustment method using segmented or non-polar uninstall way. Single machine can realize the four sections of compressor capacity **0%**5%**0%**5%. 
4. Perfect protection function: Screw water-cooled chiller have perfect protection function, such as power wrong phase lack protection, System high-voltage protection, System low voltage protection, Double antifreeze protection, Compressor overload protection, The insufficient frozen water cooling protection, Prevent frequent start protection, Compressor built-in exhaust temperature and coil overheat temperature protection and so on. 
5. Meet the temperature requirements of various industries: Screw chillers in the use of industrial cooling can be applied to a variety of cryogenic cooling, add the appropriate antifreeze in the chilled water side can be achieved 0C to - *5C the water temperature to suit different industrial cooling requirements 
6. Higher cooling energy efficiency: As the use of central air conditioning with air - conditioned boxes, fan coil and secondary heat exchanger used in conjunction with, cooling energy efficiency ratio is the biggest advantage of the water-cooled chillers. 

7. External water-cooled plate oil cooling device: In order to more fully the frozen oil and refrigerants separation, Low temperature cold water chiller external centrifugal efficient oil separator, it Can greatly reduce in low temperature and stranded in the evaporator of frozen in oil. To ensure that the compressor lubrication system security. At the same time also improves the heat transfer effect of the evaporator. 
8. Plus liquid spray technology: To further ensure compressor motor not overheat, Screw water-cooled chiller use plus liquid spray technology, with low temperature cold media on the motor cooling directly. To ensure the long-term and stable operation of the compressor. 
9. Green environmental protection: In order to better protect the atmosphere, it Can producte green environmental protection etc cooling medium refrigeration and air conditioning equipment not only in adopts HFC**7C and HFC**4A, but also in HCFC*2. 
*0. Balance run: Many of the chiller with compression, microcomputer automatic memory will be per compressor operation time, start the next time it will be activated running less time compressor. 
*1. Remote control: Each chiller with remote control function, the computer controller is equipped with RS**5 communication interface standards, open communication protocol, all kinds of building monitoring system connected even remote different ground monitoring. 
*2. Cold water chiller recyclable: In today \'s increasingly tense energy, waste heat use will have long-term economic value, on this basis, the Division I developed a heat recovery chiller can be full recovery of the original go condensing waste heat released into the environment. 
*3. Waste heat & secondary condensation: Rely on waste heat generated when the pump cooling system to take domestic hot water, without additional consumption of electricity, fuel; Almost zero cost; No pollution, no need to add other devices, just access to water pipeline, direct access to hot water.
