It can provide 1-7ºC cold water for dairy industry cooling , agricultural and sideline product processing, poultry slaughter pre-cooling, workshop air conditioning and other cooling industries.

YS series semi-hermetic screw falling-film brine chiller units is mainly based on semi-hermetic screw compressor using R134a environmental protection refrigerant medium and glycol/Cacl2 second refrigerant. It is adopted falling-film evaporator and can provide -5~0ºC cold brine water for Food process cooling, Dairy cooling, Poultry Slaughter Pre-Cooling,Shop air conditioning,chemical industry.
 

Interpretation of model marks of units

Product highlights
1.Semi-hermetic screw compressor, no shaft seal, high reliability, no oil pump
2.Falling-film evaporator, high heat transfer efficiency, low charge
3.Water-cooled shell tube type ,efficient heat exchange tube with small volume
4.The oil return of the unit adopts injection oil return, which is simple and convenient to operate with high reliability.
5.Liquid solenoid valve adopts electronic expansion valve to ensure stable liquid level.
6.Custom controllers provide optimal energy regulation, safety monitoring and protection.
7.On 1ºC outlet condition ,increase the valve to ensure constant outlet temperature.

Semi-hermetic screw compressor
YS/LS semi-hermetic falling film unit adopts international famous brand semi-hermetic compressor.


More reliable
Compared with the open type compressor, the semi-hermetic screw compressor has the advantages of compact structure, small volume, light weight, and without shaft seal, avoiding the leakage of shaft seal, more reliable.

High motor efficiency
Compressor motor using low-loss silicon steel sheet iron core, motor cooling runners, refrigerant inflow design, these conditions to ensure that the motor has a high efficiency, to ensure that the motor can be a long-term stable operation under adverse operating conditions.

Perfect protection module
Standard configuration protection module, with phase sequence detection, phase failure detection, motor reversal, high exhaust temperature oil temperature protection.

Economizer Application
The compressor adopts floating medium pressure (economizer return pressure) design, which enables the compressor to use the economizer whether it is running under full load or partial load, improving the overall operating efficiency under partial load, and providing a reliable guarantee for ensuring the IPLV performance of the unit.
