In industrial sectors such as plastics processing, chemical manufacturing, and electronics production, Screw Chiller Units are essential core equipment for centralized cooling of medium to large production lines. As a manufacturer with extensive background in plastic machinery, we offer screw chiller units that represent a comprehensive upgrade over traditional technology. With significant improvements in core components, control systems, and installation convenience, these units are particularly suitable for industrial applications demanding high space utilization and operational efficiency.
High-Efficiency Compressor Core
The units utilize 5:6 asymmetric profile dual screw compressors. This rotor ratio design effectively enhances compression efficiency while reducing operating noise and vibration, ensuring stable operation under long-term high-load conditions.
Precise Heat Exchange and Control
Equipped with specialized shell-and-tube condensers and evaporators, the units feature well-known brand electrical components supplemented by PLC microcomputer control systems. This enables precise temperature regulation and operating status monitoring, supporting infinite capacity control from 10% to 100% to match real-time load variations.
Superior Workmanship
Manufactured through precision processing and assembly, these units demonstrate significant improvements in reliability, energy efficiency ratio, and long-term stability. Under certain operating conditions, COP values can exceed 5.1.
Space Saving
The compact unit design minimizes floor space requirements, effectively saving equipment room space. This is particularly advantageous for facilities with limited space or renovation projects.
Factory Tested
Each unit undergoes rigorous testing and debugging before shipment. On-site performance testing is eliminated, significantly reducing project delivery timelines.
Minimal Foundation Requirements
Low vibration operation eliminates the need for special vibration isolation measures for foundations. Simple installation requirements reduce civil engineering and construction costs.
Integrated Design
Built-in stainless steel water tank and water pump are standard. On-site installation only requires connection of evaporator chilled water pipes and condenser cooling water pipes, substantially reducing field piping work.
| Parameter Category | Specifications | Selection Significance |
|---|---|---|
| Cooling Capacity Range | 200kW - 400kW | Covers medium to large industrial cooling requirements, suitable for centralized cooling of multiple plastic machines, large production lines, or high-load processes |
| Chilled Water Temperature | 5℃ - 20℃ | Meets temperature control requirements for most industrial applications including plastics processing (mold cooling, hydraulic systems), chemical processing, and cold chain applications |
| Compressor Start Method | Unloaded reduced-voltage start | Reduces starting current impact on power grid, prevents voltage fluctuations from damaging units and surrounding production equipment, enhances operational stability |
The units are equipped with comprehensive protective devices covering electrical, system operation, and environmental adaptation dimensions, ensuring equipment safety under unattended or high-load conditions:
Electrical Protection: Phase sequence protection, phase failure protection, motor overload protection
System Protection: High/low pressure protection, freeze protection, insufficient water flow protection
Operational Protection: Compressor overheating protection, oil level protection. Specialized protection for water-cooled systems effectively prevents unit failures caused by abnormal water temperature or pressure
Dual Compressor Design Advantages: Features staged cooling capacity, allowing single or dual compressor operation based on load requirements. This balances full-load cooling efficiency with part-load energy savings. Compressors can automatically alternate operation based on load changes, balancing operating hours and achieving energy savings while extending unit service life.
Application Scenarios:
Centralized cooling for large plastics processing facilities
Coordinated cooling for multiple high-power injection molding machines or extruders
Supporting equipment for large machinery demonstrations at industrial exhibitions
Plastics processing lines with fluctuating loads (such as integrated injection molding, extrusion, and blow molding lines)
