Double Shell Structure Cooling Roller Q345 Chrome Coating High Heat Transfer Efficiency Custom Capacity
The Double Shell Structure Cooling Roller Chrome Coating BOPP is engineered for superior performance in bi-oriented stretch film production, featuring advanced cooling technology with chrome-coated surfaces for enhanced durability and heat transfer efficiency.
Modern cooling rollers in bi-oriented stretch film production utilize two primary internal configurations:
- Double-Layer Single-Flow: Features outer shell, inner shell, and spiral baffle design. The working medium (water/thermal oil) enters through a single-flow heat transfer channel for effective heat dissipation.
- Double-Layer Double-Flow: Incorporates dual-path heat transfer channels for higher efficiency, though with more complex manufacturing requirements and higher cost.
