Plastic Processing Chiller Cooling capacities 3KW- 15KW
Product Introduction: 3kW-15kW Industrial Chillers - Dedicated Temperature Control Solutions for Plastics Processing
In the plastics processing industry, Industrial Chillers are essential auxiliary equipment that ensure stable operation of various plastic machinery and enhance product quality. As a manufacturer with deep roots in plastic machinery manufacturing, we thoroughly understand the stringent temperature control requirements across plastic compounding, molding, secondary processing, and auxiliary machinery applications. Targeting typical applications such as injection molding, extrusion, blow molding, thermoforming, and hydraulic systems, we introduce our 3kW-15kW Industrial Chillers - delivering precise, stable, and energy-efficient temperature control to meet the diverse needs of small to medium-sized plastic processing enterprises.
Why Choose Our Chillers?
Deep Understanding of Plastic Machinery, Mastery of Temperature Control
We are not only chiller manufacturers but also long-term users of plastic processing equipment. From injection mold cooling to extrusion line water baths, from blow molding compressed air drying to thermoforming proportional valve regulation, we understand the differentiated requirements for temperature, differential tolerance, and flow rate across various processes. Every 3kW-15kW chiller has been validated under actual operating conditions, ensuring perfect compatibility with your plastic machinery.
Coverage Across Four Major Machinery Classifications
Plastic machinery encompasses compounding, molding, secondary processing, and auxiliary machinery. Our chillers flexibly apply to:
Compounding Machinery: Spindle cooling for crushers, grinders, and mixers
Molding Machinery: Mold and roller cooling for injection molding machines, extruders, blow molders, and calenders
Secondary Processing Machinery: Process cooling for thermoforming machines, hot stamping machines, and welders
Auxiliary Machinery: Integration with automatic metering feeders, scrap recovery systems, and quick mold change devices for automated temperature control
Core Applications and Technical Advantages
Extrusion Applications
Application: Continuous production of plastic profiles, cable conduits, cables, and various plastic extrusions.
Chiller Function: Heated molten material formed through the extrusion die must be rapidly cooled and solidified in a chilled water bath, with constant water temperature maintenance.
Technical Requirements: High cooling capacity due to fast production speeds; 3kW-15kW chillers stably provide 6°C to 18°C chilled water with temperature differential control of ±1K to ±2K. For existing 10,000-liter water tanks, the chiller system may operate without a cooling tower through direct circulation.
Blow Molding Applications
Application: Production of water bottles, beverage bottles, and various containers.
Chiller Function: Provides low-temperature cooling source for compressed air drying systems, removing moisture from compressed air to ensure clean, dry air supply.
Technical Requirements: Chilled water temperature 6°C to 12°C, can share the same cooling source with mold cooling for improved system integration. 3kW-15kW units can support 1-4 blow molding machines.
Injection Mold Cooling
Application: Temperature control for various injection molded products.
Chiller Function: Shortens plastic solidification time, improves dimensional accuracy and surface quality of finished parts.
Technical Requirements: Chilled water temperature 6°C to 18°C, temperature differential ±2K or ±1K. Cooling capacity requirements correlate with injection shot size; 3kW-15kW power range suits small to medium injection molding machines with clamping force of 50-300 tons.
Thermoforming Applications
Application: Production of thin-wall containers such as yogurt cups and food containers.
Chiller Function: Plastic sheets are formed using heated molds under controlled conditions, requiring extremely tight chilled water temperature differential tolerance.
Technical Requirements: Proportional chilled water valves essential for achieving ±0.5K high-precision temperature control. 3kW-15kW chillers can be equipped with electric proportional valves to meet stringent thermoforming requirements.
Hydraulic System Cooling
Application: Hydraulic systems for mold opening, closing, and material injection in injection molding machines and extruders.
Chiller Function: Absorbs hydraulic pump energy, controlling oil temperature ≤60°C to prevent oil degradation.
Technical Requirements: Recommended cooling water temperature approximately 27°C. Due to different temperature requirements from mold cooling, independent control via electric water valves or separate cooling circuits is recommended. 3kW-15kW chillers can be configured with dual temperature control systems to simultaneously meet both mold and hydraulic system requirements.
Performance Characteristics
Precise Temperature Control, Intelligent Regulation
Advanced microprocessor controllers with digital temperature display enable setting of 6°C to 18°C chilled water outlet temperature. High-precision temperature sensors achieve differential control of ±1K, with thermoforming applications optionally equipped with proportional valves for ±0.5K ultra-precision regulation.
Energy Efficient, Stable and Reliable
The 3kW-15kW power range utilizes high-efficiency scroll compressors matched with shell-and-tube or plate heat exchangers, achieving energy efficiency ratios above 3.0. Designed for 24-hour continuous operation, meeting three-shift production requirements of the plastics processing industry.
Multiple Protections, Safe Operation
Standard features include compressor overload protection, high/low pressure switches, freeze protection thermostat, pump flow switch, phase reversal protection, and automatic reset after power failure, ensuring safe operation under demanding conditions.
Compact Design, Easy Installation
Integrated design occupies only 1-2 square meters floor space. Air-cooled models require no cooling tower; water-cooled models can match existing cooling tower systems. Standard equipment includes stainless steel water tank and pump, with optional remote communication interfaces for integration with factory automation systems.
Flexible Customization, Wide Adaptability
Cooling Capacity: Multiple specifications including 3kW, 5kW, 8kW, 10kW, 12kW, and 15kW
Temperature Range: -20°C to +30°C optional
Pump Power: 0.5kW to 2.2kW, meeting various head and flow requirements
Special Options: Explosion-proof, corrosion-resistant, high-temperature, proportional valve, and dual temperature control types
