60 HP air cooled screw water chiller


Air-cooled screw chiller is one kind of screw chillers that can supply a large cooling capacity for industrial cooling and air conditioning applications.


The working principle of air-cooled screw chiller is: The shell and tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load of water, which causes the water to cool down and generate cold water.


The heat is brought to the fin-type air-cooled condenser through the function of the screw compressor, and then dissipated to the outside air by the cooling fan.


OUMAL is a professional air-cooled screw chiller manufacturer with over 15 years of experience.

60 HP air cooled screw chiller

Air-cooled screw chiller application:

Plastic industry: accurately control the mold temperature of various plastics processing, shorten the plastic molding cycle, and ensure the stability of product quality.

Electronics industry: Stabilize the molecular structure of electronic components on the production line, improve the qualification rate of electronic components,

Electroplating industry: control the electroplating temperature, increase the density and smoothness of the plated parts, shorten the electroplating cycle, and improve the production efficiency

Construction industry: supply chilled water for concrete to make the molecular structure of concrete suitable for the requirements of construction purposes, effective Enhance the hardness and toughness of concrete.

Vacuum coating: control the temperature of the vacuum coating machine to ensure the high quality of the coated parts.

Food industry: used for high-speed cooling after food processing to adapt to packaging requirements. There is also controlled fermentation, The temperature of the food, etc.

Chemical fiber industry: freeze-dry air to ensure product quality.

Dairy products, beverages; the production process often requires rapid cooling after heating, The steel pipe, water tank, and water pump of the chiller are required to be made of stainless steel to meet sanitary requirements.

Medicines, biological products; low temperature and low humidity environment is required during production and storage.

The line needs to be heated to reach a certain temperature before starting, and it needs to be cooled by chilled water due to its own heat generation after starting

To keep the temperature low.

Tempered glass; the general glass is heated at high temperature and then quickly cooled, the cooling water temperature should not be too high, otherwise

Will affect the quality of tempering. The industrial chiller is used to provide frozen water for cooling, and the water temperature does not love the influence of the ambient temperature.

Ensure the quality of the product.

Aquaculture; hotels, seafood restaurants, seafood farms, aquariums, providing frozen water in summer and heat in winter.
