Last week, we finished a customized order of water cooler for Quincy air compressor. The heat tube of this shell and tube heat exchanger is made of copper to roll fin outside. The product adopts the immovable tube-plate which is the traditional structure and has high cooling effect. It's suitable for cooling of hydraulic oil or natural air. This type of water-cooled heat exchanger has bigger heating surface but little size. They're widely used in air compressor, hydraulic equipment and plastic machinery, etc.
