Introduction of air-cooling chiller

The chiller is a refrigeration equipment composed of three major systems: refrigeration system, water recycling system, and electrical system.

The core system is refrigeration.

Refrigeration system is mainly composed of compressor, evaporator, condenser, and expansion valve.

Water recycling system is mainly composed of water pump, pipelines and related valve components.

Electrical system is mainly composed of temperature controller and electrical components. This chiller has fin-type condensers that dissipate heat to

surrounding through one or more external rotor fans.

Air-cooling chiller advantages: It consolidates refrigeration system, water pump, water tank, and control system all together. With power and water

connection, Clients can easily install it on site. The DIY installation is quite easy.
