Pre-Heater

Features:

1、High-Efficiency Heat Transfer: Large-diameter preheating cylinder with a hard-chromium-plated, precision-ground surface for efficient heat transfer and durability.

2、Precise Temperature & Moisture Control: Adjustable wrap angle precisely controls heat input, maintaining base paper moisture at 8%–12% for better flexibility and bonding.

3、Independent Layer Control: Multiple preheaters allow independent heat adjustment for each cardboard layer, helping prevent warping and delamination.

4、Reliable Construction: Pressure-vessel-compliant cylinder design ensures smooth steam flow and uniform heat distribution.

5、Intelligent Control: PID temperature control integrates with production line systems and automatically adjusts the wrap angle according to line speed and material, supporting speeds up to 300 m/min or higher.
