Introduction of water-cooled chiller box

The chiller is a refrigeration system composed of a compressor, evaporator, condenser, and expansion valve. Its condenser (radiator) is a shell&tube style, and it exchanges heat to cool water for external cooling water tower and cooling water pump.

The core advantage of water-cooling chillers: high energy efficiency ratio, used in places with cooling water sources. Low noise, etc.

Application areas:

Davosi water-cooling chiller boxes are widely used in semiconductor processing, chip packaging, aerospace, reliability testing, chemical reactions, biopharmaceuticals, surface treatment, material processing, vacuum coating,

scientific experiments and other industries. It can accurately control the heat generated in modern industries and processes, improve production efficiency and ensure production quality. There are many varieties and types of this

chiller type.
