DC INVERTER CHILLER AND TRADITIONAL CHILLER IN THE PLASTICS INDUSTRY

OVERVIEW OF CHILLERS IN THE PLASTICS INDUSTRY

During plastic injection molding, the mold temperature plays a decisive role in the final product’s quality. If cooling is unstable, defects such as surface cracks, warping, or shrinkage may occur. A chiller provides a reliable cooling solution by maintaining a steady flow of chilled water to keep the mold temperature at the ideal level.

Currently, there are two major types of chillers widely used in the plastics industry:

Traditional chiller: Uses an on/off compressor that operates in cycles - turning on and off based on cooling demand.
DC Inverter chiller: Equipped with inverter technology, allowing the compressor to adjust its speed and cooling capacity in real time according to actual load requirements.

Both systems can meet cooling demands, but their performance and operating costs differ significantly.

COMPARISON BETWEEN DC INVERTER CHILLER AND TRADITIONAL CHILLER

Structure and Operating Principle

Traditional chiller: The compressor operates in an on/off cycle. When the cooling load decreases, the system shuts down to save energy; when the load increases, it restarts. Frequent restarts cause temperature fluctuations and higher power consumption.
DC Inverter chiller: The inverter-driven compressor automatically adjusts its speed to match the actual cooling load, ensuring stable water temperature and significantly reducing energy consumption.

Energy Efficiency

Traditional chiller: Consumes more power due to the on/off operating mechanism, especially when the plant is not running at full capacity.
DC Inverter chiller: Can save 25–40% of electricity compared to traditional models, making it ideal for plastic factories that operate continuously.

Impact on Product Quality

Traditional chiller: Temperature fluctuations during cooling can lead to product defects such as warping, cracking, or dimensional errors.
DC Inverter chiller: Maintains stable cooling temperature, minimizes defects, improves product quality, and reduces rejection rates.

Investment and Maintenance Cost

Traditional chiller: Lower initial cost, simple components, and easy to maintain—suitable for small factories or short-term projects.
DC Inverter chiller: Higher initial investment but offers long-term energy savings and lower overall operating costs.

Practical Applications

Traditional chiller: Suitable for small-scale workshops, intermittent operations, or processes with less demanding cooling requirements.
DC Inverter chiller: Ideal for large-scale manufacturing plants, export-oriented production lines, or operations where electricity cost is a major expense.

THE SHIFTING TREND IN THE PLASTICS INDUSTRY

Today, plastic manufacturers face dual challenges: ensuring high product quality while controlling production costs. With rising electricity prices and the global push toward sustainable manufacturing and CO₂ reduction, energy efficiency has become a top priority.

As a result, many companies are transitioning from traditional chillers to DC Inverter chillers. The benefits are especially clear in large-scale production or export projects targeting demanding markets such as Japan and Europe. Inverter technology not only saves energy costs but also enhances product quality and reduces business risks.
