When plastic processing generates excessive heat, unstable cooling can affect cycle time, product quality, and equipment reliability. An Industrial Water Chiller gives you controlled process cooling for injection molding, extrusion, and other plastic manufacturing operations. NIASI designs and manufactures industrial cooling equipment as part of its broader plastic processing equipment portfolio, helping you integrate cooling with material conveying, drying, dosing, and other production processes.
NIASI, founded in 2008, focuses on material conveying systems and auxiliary equipment for plastics. Its Water Cooled Screw Chiller uses semi-hermetic screw compressors, tube-in-shell heat exchange, microcomputer refrigeration control, and multiple safety protection functions to support demanding industrial cooling requirements.
Why Use an Industrial Water Chiller for Plastics?
Plastic processing equipment continuously generates heat during molding, extrusion, and related operations. Without stable cooling, you may experience longer cycles, inconsistent processing conditions, or unnecessary equipment stress.
A water cooled industrial water chiller can provide a dedicated cooling loop for production equipment. NIASI’s Water Cooled Screw Chiller offers rated cooling capacities from 13.1 kW to 558 kW, depending on the model and configuration.
Key characteristics include:
- Water-cooled screw compressor design for industrial refrigeration applications
- 13.1–558 kW rated cooling capacity across the listed models
- 1 or 2 compressor configurations depending on the series
- 100-75-50-25% capacity control for the listed screw compressor configuration
- Tube-in-shell heat exchanger for the evaporator
- Microcomputer-controlled refrigeration system
- High/low-pressure, overheat, antifreeze, overcurrent, phase-sequence, and oil-pressure protection
These features allow you to match cooling capacity and operating requirements more closely to your production process.
Water Cooled Screw Chiller Specifications
For industrial buyers, capacity alone should not determine your selection. You should also consider power input, water flow, compressor configuration, heat exchanger design, and protection functions.

Because different models provide different cooling capacities and water-flow requirements, you should select the unit according to your actual thermal load rather than choosing only by physical size.
Industrial Water Chiller Applications in Plastic Manufacturing
You can integrate an industrial water chiller for plastics into several production environments where controlled cooling is required.
Injection Molding
Injection molding machines need consistent temperature control to support repeatable production cycles. A suitable chiller can supply cooling water to the process and help remove heat generated during operation.
Plastic Extrusion
Extrusion lines can require continuous cooling as molten polymer moves through the processing system. A water cooled chiller for extrusion can support stable process conditions while operating continuously.
Medical and Automotive Plastics
NIASI states that its equipment serves sectors including automotive components, medical devices, wire and cable, food packaging, plastic pipes, extrusion blow molding, and granulation. In these applications, stable process cooling can form part of a broader auxiliary equipment system.
How to Select a High Efficiency Industrial Water Chiller
Before purchasing an energy saving industrial water chiller, follow a structured evaluation process.
- Calculate your cooling load
Determine the heat generated by your machines and process. Include operating hours and expected production changes. - Check required water flow
Compare your process flow requirement with the chiller’s available water-flow range. NIASI’s listed models range from 22.5 to 95.7 m³/h. - Select compressor configuration
Choose a single- or double-compressor model according to capacity and operating requirements. - Review electrical conditions
Confirm that the available power supply matches the equipment specification, including approximately 380 V, three-phase operation. - Evaluate protection and control
Check pressure, temperature, current, phase, antifreeze, and oil-pressure protection before finalizing the system. - Consider system integration
If you operate a complete plastics production line, evaluate how the chiller will work with dryers, blenders, loaders, conveying systems, and other auxiliary equipment.
NIASI Industrial Cooling Equipment for Plastic Processing
NIASI does more than manufacture chillers. The company develops equipment across the plastic raw material handling and processing workflow, including dehumidifying dryers, gravimetric blenders, hopper loaders, mold temperature controllers, intermixers, and raw material unloading equipment.
Its manufacturing operation includes CNC machine tools, laser cutting equipment, hydraulic presses, CNC lathes, milling machines, powder coating equipment, and testing devices. NIASI also states that its R&D and manufacturing teams cover mechanical design, automation engineering, hardware and software development, process analysis, and quality inspection.
This integrated capability can be useful when you need an industrial cooling system for plastics that works alongside other auxiliary equipment rather than operating as an isolated machine.
FAQ
1. What is an Industrial Water Chiller?
An Industrial Water Chiller is a refrigeration system designed to remove heat from water or process fluids for industrial applications. The cooled water can then circulate through production equipment or heat-exchange systems.
2. What cooling capacity does the NIASI Water Cooled Screw Chiller provide?
The listed NIASI models provide rated cooling capacities from 13.1 kW to 558 kW, with different models offering different water-flow, power-input, and compressor configurations.
3. Is a water cooled screw chiller suitable for plastic processing?
Yes. Water cooled screw chillers can be used for industrial process cooling where stable cooling water is required. For your specific plastic processing line, you should size the chiller according to thermal load, water flow, operating conditions, and equipment requirements.
Conclusion
Choosing the right Industrial Water Chiller requires more than comparing cooling capacity. You should evaluate process load, water flow, compressor configuration, control requirements, electrical conditions, and integration with your existing plastic processing equipment. With its Water Cooled Screw Chiller and wider range of plastics auxiliary equipment, NIASI provides an integrated equipment option for manufacturers seeking stable process cooling and material handling support.
