Industrial Water Chiller Water Cooled Chiller Industrial Refrigeration Process Chiller Air Conditioning Water Chiller Efficiency Water Chiller
Industrial refrigeration ener saving water chiller
Screw chiller capactiy range is from 140kw to 760kw, water cooling temperature if adjustable 5 - 30 ℃. See our screw chiller catalogue for more details.
Screw chiller is perfect choice that use for process cooling for heat dissipation and heat extraction as it is vital to yield high quality products. This includes process such as plastic injection ,plastic extruding ,bottle blowing, film blowing and many other thermoplastic materials that need to be heated to their molten temperature and then be solidified through cooling water from industrial chiller.
Water-cooled chiller systems have a cooling tower and use cooling water for heat dissipation and it's higher efficiency than air-cooled chillers, which is perfect choice that use for process cooling for heat dissipation.This system includes item below.
Water-cooled chiller
Cooling tower
Cooling pump
Insulated water storage tank
How to decide between air cooled and water cooled chiller types?
In an air-cooled chiller, hot refrigerant entering the copper tube fin condenser and it is exposed to atmospheric air for heat dissipation.The air-cooled chiller has built-in fan and no need cooling tower for operation, easier installation, lower maintenance cost and save water.
On the other hand, in a water-cooled chiller, hot refrigerant gas is sent to a water-cooled heat exchanger (shell and tube condenser) for heat dissipation. Thus, it will need cooling water from a cooling tower.

Water-cooled screw chiller featurers
- Adopting high-efficiency and energy-saving compressors of world class grade brands, high-quality condensers and evaporators, high cooling efficiency, stable performance, low noise and long service life.
- The control system is adopting Siemens PLC controller and LCD touch screen , accurately controls the cooling capacity and cooling load of the unit in real time to achieve the best matching state, to ensure that the unit runs at the best efficiency and to reduce operating costs.
- Screw compressor chiller capacity control can adopt four-stage (100%-75%-50%-25%), three-stage (100%-66%-33%) or stepless control system.
- High-efficiency internally threaded copper pipes enhance the heat transfer effect are more energy efficient.
- The machine is all made of oshell and tube evaporator and condenser, the welded structure is simple, sturdy structure, high quality, compact structure, long life and so on.
Advantage of water cooling chiller
- Energy Efficiency.Water-cooled chillers are generally more efficient than air-cooled chillers by using cooling water for heat dissipation from cooling tower.
- Low noise.Water screw cooled chillers are quieter operation than air-cooled systems.
- No open space needed.Water-cooled chillers no need to stay outdoors in an open space with plenty of fresh air to operate. The chillers installation can be indoor, which makes them ideal for companies that don't have enough outdoor space.
- Lower operational costs and save time
Benefit of process chiller applications
- The ability to maintain constant and precise control of the process temperature.
- The cooling fluid can be delivered directly to the application heat source to increased production speed and ensure efficiency production
- Accurate temperature control capability, to ensure the highest quality final products.
- Water chiller systems prevent damage to heat-sensitive industrial components preventing undesirable repair downtime that might slow or even halt production altogether.
