  Product Description  Intelligence:For machine unit with multiple compressors, the microcomputer will record the running time of every compressor, so the less running one will be activated in priority next startup.Meantime when in a unloading operation, the one with more run time will be unloaded and stop in priority, in order to make balance of every compressors and prolong the service life of the entire unit.
Stability:Winday integrates the world's leading suppliers for every part equipped in the machine unit to ensure high quality of each component, thus ensure the stable performance of the entire machine.

Wide Range:In order to meet different cooling temperature requirements of different industries, we have many series of professional scroll industrial compressors with outlet chilled water range 15 ºC ~ -35 ºC, sophisticated technology to ensure stable work under extreme conditions;Box-type industrial chillers can achieve a variety of low-temperature water carriage, like 0 ~ -35 ºC chilled water temperature by adding appropriate antifreeze to the chilled water side.

Efficiency:Equipped with professional international advanced scroll industrial compressor, which significantly improve the compressor efficiency and heat exchange efficiency to ensure efficient plant operation.

Energy-saving:WINDAY unit uses self-developed energy-saving control procedures to ensure the stable and efficient operation of the unit by adjusting the stations of the unit automatically according to the specific working conditions.

Simple:The unit structure is simple and has a nice human-computer interface, which you can set the working conditions free.For the unit which is already set, the unit can operate automatically and adjust the energy in time.Very simple operation!

Anti-corrosion:Low temperature brine-type unit is equipped with evaporator made of high efficient imported anti-corrosion materials, not ordinary anti-corrosion treated materials.Under the circumstance that not to influent heat exchange efficiency, this can ensure evaporator's usage life and avoid piercing and permanent damage to the unit caused by the secondary refrigerant.

Safety:The unit has a perfect protection system, and all the failures are displayed in operation screen both in Chinese and English, thus avoid damage from bad working conditions and prolong the usage life of the machine.Standard safety methods are as follows:Compressor overload protection, compressor overheating protection, pump overload protection, cooling fan overload protection (air-cooled), high-pressure protection for cooling system, low pressure protection for cooling system, too high/too low protection for water flow,  anti-freeze protection, anti-frequent startup protection, power default phase protection, power reverse protection, phase dislocation protection, overvoltage protection, low-voltage protection.The individual module designed scroll compressor can realize free combination of volume, and easy to use with high reliability,

Environmental protection:Given the impact on the quality of the environment, our product uses refrigerant R22, also other environmental friendly refrigerant R407C, R134A, R410A, R404A, which can be customized as requirement.
