40 Ton Air Cooled Industrial Water Chiller for Sheet Extrusion Production in Chemical Industry

40ton Air Cooled Industrial Water Chiller  for sheet extrusion production
The chiller is a key supporting equipment in sheet extrusion production.
 
Through precise temperature control and efficient heat dissipation, it not only ensures product quality and production efficiency, but also reduces energy consumption and maintenance costs.
 
Selecting the right chiller (such as cooling capacity and flow matching) is crucial to optimizing the process and improving economic benefits.

1. Temperature control and stability
Melt cooling: During the sheet extrusion process, the plastic raw materials need to be quickly cooled and shaped after being heated and melted. The chiller circulates cooling water to accurately control the temperature of the mold, calender roller or cooling roller to ensure uniform cooling of the sheet and avoid deformation, warping or surface defects.
Prevent overheating: The extruder screw and barrel may generate additional heat due to friction during operation. The chiller assists in heat dissipation and maintains the equipment within a safe temperature range.
2. Improve product quality
Reduce internal stress: Through uniform cooling, the chiller can reduce the internal stress caused by temperature difference inside the sheet and prevent cracking or deformation during later processing (such as cutting and thermoforming).
Surface finish: Rapid cooling can solidify the surface of the sheet, ensure its smoothness and reduce defects such as bubbles and streaks.
3. Improve production efficiency
Shorten the molding cycle: An efficient cooling system can speed up the shaping of the sheet, reduce the waiting time of the production line, and increase production capacity.
Continuous production: Stable temperature control avoids shutdown due to overheating of the equipment and ensures long-term continuous operation.
4. Extend equipment life
Prevent thermal damage: The screw, mold and other key components of the extruder are prone to aging or wear at high temperatures. The chiller reduces the heat load by dissipating heat and extends the service life of the components.
Reduce maintenance costs: Stable operating temperature can reduce equipment failure rate and reduce maintenance frequency.
5. Adapt to diverse production needs
Flexibly adjust temperature: Different materials (such as PP, PET, PVC, etc.) have different requirements for cooling temperature. The chiller can meet various process requirements through precise temperature control.
Energy saving and environmental protection: Modern chillers use high-efficiency refrigeration technology (such as frequency conversion control) to reduce energy consumption and wastewater discharge.
