1. Air cooled type
The oil cooler and compressed air aftercooler of air-cooled screw air compressor are integrated, and high-efficiency aluminum plate fin heat exchanger is adopted.
The unique fin structure increases the secondary heat transfer area, promotes the turbulent flow and improves the heat transfer coefficient;
The heat exchange area is increased by 30% compared with the European model, and the surplus is large. Even in the humid and hot weather in the south, the normal use will not be affected;
The cooling fan is separated and installed, and there is no fan interference on both sides of the cooler, which is convenient for cleaning;
2. Water cooled
The cooling system of screw compressor is composed of oil cooler and compressed air aftercooler.
The oil cooler adopts a relatively new type of continuous throttling plate, highly efficient rolling fin tube and tube type cooler, with light weight and high heat exchange efficiency.
The heat exchange area of the oil cooler is increased by 30% in the design, which ensures that even if the cooler has a little scaling, it will not affect the normal use and prolong the cleaning and maintenance cycle of users.
The compressed air aftercooler adopts the internal spiral mesh type high-efficiency cooler produced by British technology, which is characterized by small volume (its volume is only 1 / 3 of the general tubular type), light weight and high heat exchange efficiency.
