Advanced Energy-efficient molding cooling solutions
Shanghai Peiyu Packaging Technology Co.,Ltd.
Modern PET preform injection molding requires precise temperature control to ensure optimal product quality and production efficiency. Our integrated cooling systems – including industrial chillers, cooling towers, and air compressors – are engineered specifically for the demands of plastic bottle preform manufacturing.
High-Performance Industrial Chillers
Our energy-efficient chillers maintain critical mold temperatures between 5°C–35°C (41°F–95°F) for consistent PET preform crystallization. Featuring:
±0.5°C temperature stability with PID control
30% energy savings with variable speed compressors
Corrosion-resistant evaporators for water-glycol mixtures
Compact designs (5HP to 200HP capacity) saving floor space
Cooling Tower Systems for Continuous Operation
The closed-loop cooling towers complement chiller operations with:
500–10,000 GPM circulation capacity
FRP construction resisting chemical corrosion
Automatic water treatment systems preventing scaling
Low-noise fans meeting 65 dB(A) standards
Oil-Free Air Compressors for Clean Production
Our Class-0 certified oil-free compressors deliver:
100% contaminant-free air for pneumatic controls
15–350 HP range with VFD options
40% lower energy consumption than lubricated models
Integrated dryers maintaining -40°F dew point
System Integration Advantages
Precision Temperature Control
Digital controllers maintain ±0.2°C mold temperature variations, reducing preform defects like haze or crystallinity issues.
Energy Optimization
Heat recovery systems repurpose 60% of waste thermal energy for secondary processes.
Hygienic Design
Stainless steel fluid paths and antimicrobial coatings meet FDA compliance for food-grade packaging.
