Especially in the plastic molding process, chillers can be used to cool molds, effectively improving the surface finish of products, reducing surface defects and internal stress, preventing shrinkage and deformation, enhancing demolding efficiency, accelerating setting speed, thereby significantly improving production efficiency and product quality.
Semi-Hermetic Screw Compressor
Low Noise, Low Vibration, Over 20% Energy Saving
The air-cooled screw chiller uses a semi-hermetic screw compressor, which offers advantages such as stable operation, low noise, and minimal vibration. During compression, gas enters the compression chamber from the suction end, is continuously compressed as the screws rotate, and is discharged from the exhaust end. The screw design ensures smooth and efficient gas flow. The equipment uses internationally renowned screw compressor brands such as Bitzer or Hanbell, ensuring long-term, high-efficiency, and reliable operation. Compared to traditional scroll compressors, the overall energy-saving effect is increased by over 20%, significantly reducing energy consumption.
Shell-and-Tube Evaporator
The air-cooled chiller uses a high-efficiency shell-and-tube evaporator, where the refrigerant evaporates inside the heat exchange copper tubes while water flows on the outside of the shell. To improve heat exchange efficiency, we have added a layer of approximately 2mm thick baffle inside the shell, causing the cooling water to flow back and forth, thereby enhancing heat transfer efficiency and achieving the effect of producing brine water.
The exterior of the shell is wrapped with high-performance insulation cotton to reduce energy loss and ensure stable system operation and consistent temperature.
The evaporator uses high-efficiency seamless copper heat exchange tubes. The copper tubes undergo precise 'Yuhua' processing, forming a threaded rib structure on the inner wall, which significantly increases the heat transfer area between the refrigerant and the copper tube. Compared to traditional smooth tubes, this structure doubles the heat exchange area, greatly improving overall heat transfer efficiency and refrigeration performance.
