About Water-cooled chillers
- The two popular types of industrial chillers are air-cooled
chillers and water-cooled chillers.hey have same configuration,
condenser, expansion valve, evaporator, and compressor), the main
difference is in how the refrigerant is cooled. The air-cooled
chillers use fans to cold refrigerant. However, the water-cooled
chiller use water from cooling tower.
- Industrial water-cooled chillers have a separate cooling tower
for water circulation with chiller condenser. Normally
water-cooled chillers are cheaper and more efficient.
- Water-cooled chillers can be costly to install and maintain due to
the additional cooling water tower, tanks, and water pump.
- Water-cooled units often take up less space than air-cooled units,
even with the tower, but higher cost of water.
- They have a quieter operation than air-cooled systems.
Features of water-cooled water screw chillers
- Anges water-cooled screw chillers are large cooling
capacity from 120kw and 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.
Benefits of water-cooled screw chiller
- 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 design is very compact and made of high-grade materials. It has
stronger durability and longer service life. It does not need any
kind of repair and replacement for a long time, which can save
cost.
- These industrial screw central chillers are stable
operation, high efficiency and energy saving, which are ideal
solution for process cooling applications in Injection Molding,
Blowing Molding, Extruding machine, Thermal
Forming, Beverage Filling processing, Metal Finishing and much
more.
