Spiral Heat Circulation Rollers:
The Optimal Balance of Efficiency, Stability, and Cost
Spiral channels leverage precision spiral flow guidance to force heat transfer medium (oil or water) into controlled circulation rather than random flow,delivering the most mature thermal control solution available with exceptional heat exchange efficiency.
High-Performance Heat Exchange Design
Heat transfer medium circulates at high velocity along the circumference, creating turbulent flow that significantly enhances heat transfer efficiency. For production lines requiring frequent temperature adjustments or high thermal loads, the response speed delivers exceptional performance.
Superior Lateral Temperature Uniformity
Multi-spiral convection design effectively counteracts inlet-outlet temperature differences. Eliminates stagnant zones found in traditional hollow rollers, preventing uneven film shrinkage and quality inconsistencies caused by temperature gradients.
Lightweight High-Rigidity Structure
Features dual or triple-layer sleeve design, reducing weight compared to solid rollers. This decreases motor load and startup energy consumption while maintaining superior rigidity and operational stability.
Ultimate Surface Quality with Cost Efficiency
Achieves Ra 0.01 μm ultra-mirror grade surface finish. In coating and calendering applications, delivers drilled-roller-level quality performance with significantly more competitive budgets and lead times.
Maintenance Advantage: Relatively simple channel design with minimal resistance, pump-friendly operation. Internal surface resists scale buildup, making cleaning and maintenance procedures straightforward.
