Application:
Our water cooled screw chillers, water cooled screw type low temperature unit, flooded type water hillers, air-cooled screw chiller, air-cooled, water-cooled box type chillers products have been widely used in chemical industry, chemical fiber, plastics, oil, food, as long as the industry, printing, electroplating, electronics and other industries

Recommend products:
Usually cooling tower offers chilled water to water cooled chiller, here we recommend our dry cooler to instead of cooling tower.
