Water-Cooled Screw Chiller 720ton Water Chiller Central Chiller System Industrial Water Cooled Screw Chillers

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 condense depending on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature.

Normally water-cooled chillers are cheaper and more efficient, with the disadvantage of high water consumption and cost more to install and maintain.

This system has several essential components including:

Chiller

Cooling tower

Condenser cooling pump

process chilled water pump

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.

The most common types of water cooled chillers use water from an external cooling tower to cool the refrigerant in the condenser.They need to install cooling tower and cooling pump for operation. since they require a constant supply of water for cooling, they might not be suitable for locations with water shortages or restrictions.

Features of water-cooled water scrw chillers

1. Anges water-cooled screw chillers are large cooling capacity from 120kwand 1600kw. The chilled water temperature provided is within a range of 5℃-30℃.
2. High efficient shell and tube type evaporator to connect with large water tank directly.
3. 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.
4. 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.
5. PLC control system,integrated controller, fully automatic operation, to provide fault warning.
6. Complete safety devices are equipped ,including compressor over temperature, over current, high and low pressure, over temperature, flow switch, etc.

Benefits

1. Water-coold screw chillers could accurately provide the needed temperature for industrial manufacturing and largely improve efficiency and product quality.
2. The industrial water chillers are use to maintain constant and precise control of the process temperature.
3. Chillers can decrease equipment depreciation and degradation to cut down on operating expenditures.
4. 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.
5. 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.
