GX Screw chiller
Performance of screw chiller:
It is an efficient and reliable industrial chiller. Its main component uses a screw compressor, so it is called a water-cooled screw chiller.
It uses a screw compressor and water-cooled heat dissipation method, with excellent cooling capacity and stable performance. The chiller is equipped with a cooling tower or cooling water circulation system, and can meet a wide range of industrial needs through the heat dissipation of external cooling water.
Purpose of screw chiller:
It has a wide temperature control range and cooling capacity, and can be accurately controlled between 3℃ and 50℃, suitable for plastic processing, chemical, pharmaceutical and other industries. Water-cooled screw chillers are ideal for industrial cooling, ensuring stable operation of equipment and processes.
How to choose a chiller 2 conventional models
Water-cooled screw chiller
A cooling tower is required to dissipate heat from the condenser.
The built-in fan cools the chiller and is suitable for environments with good ventilation.
Screw chiller
Screw cooling water function
Used in plastics (injection molding, extrusion, bottle blowing industry), plastic packaging industry, automobile manufacturing industry, laser welding, electronic manufacturing, electroplating, pharmaceutical chemicals, ultrasonic cooling, printing and other industries, to maintain stable operating temperature of equipment and processes and improve production efficiency. It is usually suitable for production and processing equipment with large cooling requirements. It is widely used in plastic processing industries such as injection molding and extrusion. It can meet various process cooling requirements and greatly improve the production efficiency and product quality of plastic molding machines.
