How to clean the fins of an air-cooled chiller
Aug 24 , 2021
The air-cooled chiller is a kind of industrial chiller, and the main working principle is not much different from that of the water-cooled chiller. Air-cooled chiller is a machine that cools water at room temperature to a certain temperature through the compressor of the chiller. It is generally common in industrial manufacturing. However, air-cooled chillers are widely used, mainly for high-speed...
