Low-Power Suction Machine
Water-Cooled Dual-Head Screw Chiller
Water-Cooled Single-Unit Screw Chiller
High-Power Suction Feeder
Structural Features
1. Twin compressor design
- Equipped with two high-efficiency semi-hermetic screw compressors, each can operate independently or jointly, ensuring system efficiency under both partial and full load conditions.
2. Double refrigeration circuits
- Two independent refrigeration circuits that serve as backups for each other, ensuring continuous and safe operation of the unit. Even if one system fails, the other can operate independently, preventing total system shutdown.
3. Inverter control
- The compressors, cooling water pumps, and chilled water pumps can all be controlled with Inverter, precisely matching the load to reduce energy consumption and mechanical impact.
4. High-efficiency heat exchangers
- Uses shell-and-tube evaporators and condensers with high heat transfer coefficients, low water-side resistance, and anti-scaling and easy-to-clean designs.
5. Intelligent control system
- Equipped with a microcomputer/PLC fully automatic control system, featuring automatic load adjustment, fault diagnosis, remote communication interfaces, and can be integrated into a building automation system (BAS).
Performance Advantages
· High Energy Efficiency Ratio (COP): The Inverter technology shows significant advantages under partial load operation, saving 20%–35% more energy compared to traditional fixed-frequency units.
· Stable and Reliable Operation: The Double-system, Double-compressor design greatly enhances system redundancy and safety.
· Intelligent Regulation: Automatically optimizes compressor operating modes based on real-time load and environmental conditions, reducing the need for manual intervention.
· Low Noise and Vibration: Screw compressors operate smoothly, and combined with Inverter soft start, noise and vibration are greatly reduced.
· Convenient Maintenance: Modular design allows key components to be individually disassembled, reducing maintenance difficulty and costs.
Industry Applications:
Chillers are widely used in various industrial fields such as plastics, electronics manufacturing, electroplating, pharmaceuticals and chemicals, ultrasonic cleaning, and printing. 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, and speeding up the setting process, thereby significantly increasing 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.
