1. Water-cooled 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.

Screw compressor has the advantages of simple structure, large cooling capacity, energy saving and high efficiency. It does not have the cylinder required by piston compressor, piston, piston ring, cylinder liner and other vulnerable parts, so it operation is more stable and reliable, low failure rate and longer service life. Industrial water cooled chiller maintenance is very easy and save cost.

Piston compressor 's applicable pressure range is wide, price is relatively cheap, easy to operation.But it has complex and heavy structure, many wearing parts and heavy maintenance workload.

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 to dissipate heat.

The most common types of water 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.

1. All the chillers are provided with 12 months free maintenance service.
2. Provide technical explanation, chiller debugging support, technical training and chiller maintenance guidance.
3. If necessary, after-sales engineers can be on-site service confirmed by both parties through communication .In some areas, local dealers can provide fast and convenient service.
4. Provide the air chiller and water chiller required parts quickly to ensure the normal use of customers.If necessary, part of the wearing parts can be provided for backup after confirmation by both parties.
