150HP Air Cooled Screw Chiller Industrial Process Water Chillers For Multiple Injection Molding Machines

Air-cooled screw chillers have significant advantages in scenarios with multiple injection molding machines. They can meet the efficient cooling needs of multi-machine collaborative production while taking into account energy saving and convenient operation and maintenance. The following are its core benefits:

1. Centralized and efficient cooling, cost saving

One machine with multiple controls: A single air-cooled screw chiller can provide centralized cooling for multiple injection molding machines (need to match the total cooling capacity requirements), avoiding repeated investment in each injection molding machine with a separate chiller, and reducing equipment procurement and installation costs.

Energy saving and consumption reduction: The screw compressor supports multi-stage or stepless energy regulation, and can automatically match the cooling output according to the real-time load of multiple injection molding machines, avoiding "energy waste" at low load, and the comprehensive energy efficiency ratio (COP) can reach 3.0~3.5.

2. Stable temperature control to improve injection molding quality

Precise temperature control: The water temperature fluctuation can be controlled within ±1℃ to ensure uniform cooling of the mold and reduce defects such as shrinkage, warping, and flow marks caused by temperature differences in injection molding parts.

Quick response to load changes: The intermittent operation of the injection molding machine (cycled mold opening and closing) causes large fluctuations in heat load. The impact resistance and frequency conversion technology of the screw compressor can quickly respond to changes in cooling demand and maintain stable water temperature.

3. Save space and simplify installation

Integrated design: The air-cooled unit does not require an external cooling tower and water pump, and occupies a small area, which is especially suitable for workshops with limited plant space.

Quick deployment: It only needs to connect the cooling water pipeline and power supply to operate, and supports multiple injection molding machines in parallel (distribute the flow through the water distributor), shortening the production line transformation cycle.

4. Low maintenance and high reliability

No dependence on water quality: The air cooling system does not need to deal with problems such as scale and algae, avoiding the decrease in heat exchange efficiency or pipe blockage due to poor water quality (the injection molding machine mold cooling channel is narrow and sensitive to water quality).

Long life design: The screw compressor has a stable structure and an operating life of more than 10 years, which is suitable for injection molding workshops with 24-hour continuous production.

5. Adapt to multiple scenarios and environments

Advantages in water-scarce areas: completely dependent on air cooling, no cooling water consumption, suitable for areas with water shortage or strict environmental protection requirements.

High temperature environment resistance: The optimized air-cooled unit can operate stably at an ambient temperature of 45°C (by strengthening the fan or increasing the condenser area), avoiding the cooling capacity attenuation caused by high temperatures in summer.

6. Flexible expansion and intelligent management
Modular expansion: If the number of injection molding machines is increased in the future, the capacity can be flexibly expanded by connecting multiple chillers in parallel or upgrading large-capacity units.

Intelligent monitoring: Supports remote control, fault warning and energy efficiency analysis, facilitating multi-machine collaborative management.
