Water-cooled screw chiller
Water-cooled screw chiller systems are especially used for large cooling loads, they have a cooling tower for refrigerant heat dissipation that higher efficiency than air-cooled chillers which use fans for refrigerant heat dissipation.
Water-cooled chillers are more efficient because they use cooling water from a cooling tower to cold the refrigerant in the chiller systems.
Normally water-cooled chillers are cheaper and more efficient, but higher cost in installation and maintenance due to need to install cooling tower and water consumption and water treatment and so on.
This water cooled chiller system has several essential components including:
Chiller
Cooling tower
Condenser cooling pump
Process chilled water pump
Water tank

Industrial Chiller Features
- Anges water-cooled screw chillers are large cooling capacity from 120kwand 1600kw. The chilled water temperature provided is within a range of 5℃-30℃.
- High efficient shell and tube type evaporator to connect with large water tank directly.
- The shell and tube condenser is low condensing temperature, good cooling effect, suitable for medium and large refrigeration system.It can run easily even in hot weather.
- Screw chiller compressor capacity control can be used in four stages (100%-75%-50%-25%) or three stages (100%-66%-33%) and no stage control system.
- PLC control system,integrated controller, fully automatic operation, to provide fault warning.
- Complete safety devices are equipped ,including compressor over temperature, over current, high and low pressure, over temperature, flow switch, etc.
Water chiller benefits
- Water-coold screw chillers could accurately provide the needed temperature for industrial manufacturing and largely improve efficiency and product quality.
- The industrial water chillers are use to maintain constant and precise control of the process temperature.
- Chillers can decrease equipment depreciation and degradation to cut down on operating expenditures.
- The cooling fluid is recirculated reducing waste and cost.
- Screw compressors can achieve comparable part-load efficiencies, whether you run your chiller more often at part or full load to save energy.
The difference between Air-cooled chiller and Water-cooled chiller
An air-cooled chiller refers to a chiller system that uses the ambient air surrounding the condensing unit to cool and condense the refrigerant back into a liquid. In other words, the air cooled chillers use fans for chiller's refrigerant dissipate heat, but the water-cooled needs to install cooling tower for operation.
Water-cooled chillers are more efficient with the disadvantage of having critical maintenance demands included water treatment, chiller condenser-tube cleaning, tower mechanical maintenance, and freeze protection.
