Performance
The housing of the chiller is designed with the software Solidworks of three-dimensional sheet metal and processed by the imported precision numerical control equipment, and the surface is well treated with the environmental electrostatic powder coating, which makes the chiller be elegant and durable. The water-cooled condenser adopts the shell and tube style one with the external threaded copper tube, which has high efficiency on heat dissipation , convenience on cleaning and resistance to blockage. The refrigerating capacity of water-cooled chiller is 10% more than that of air-cooled chiller.

The refrigerating capacity of water-cooled chiller is 10% more than that of air-cooled chiller.
Built-in high and low voltage, overload, delay, lack of phase, overtemperature and other protection devices ensure the operation of the equipment more stable. Selected famous brand compressors (Panasonic, Daikin, Copeland) and refrigeration electronic control components (Danfoss, Emerson, Siemens, etc.) guarantee the products with high quality. The general model control accuracy is ±1°C and the special model can reach ±0.5°C.
Multiple refrigeration circuits can be set up and each circuit can run separately, which meets the demand of variable load, favours power saving, improves the safety and stability of equipment operation, and satisfies the severe requirements for temperature in various industrial production. The normal temperature model is 5-25℃ and the low temperature model is from -25℃ to -5℃. Non-standard models can be customized based on customers’ requirements.
Application
The air cooled chillers are widely used in injection mold, laser marking welding equipment, vacuum coating machine, packaging machinery, semiconductor equipment, welding machine electrode, plasma cutting machine, spindle cooling of PCB drilling machine, etc. to protect the precision equipments and improve production efficiency.
