Until now, the calendar rolls used in the paper manufacturing process, which relied on steam or oil heating, had the drawback of reducing the strength of the paper due to low-temperature, high-pressure nip processing. This issue has been resolved by the "Jacket Roll." With an induction heating mechanism that allows for flexible temperature settings by heating the roll itself, and a heat pipe mechanism that ensures uniform temperature across the entire surface of the roll, high-precision high-temperature calendering is achieved. This creates "ideal paper" that combines excellent printability, strength, and thickness. 【Main Applications】 ■ Soft Calendar ■ Hard Nip Calendar ■ Machine Calendar ■ Super Calendar For more details, please refer to the catalog or feel free to contact us.

The "Fluid Circulation Jacket Roll" is a jacket roll equipped with a jacket chamber for fluid circulation. Thanks to the high-precision uniform temperature effect of the jacket chamber, it reduces fluid flow by 25% compared to conventional methods, while achieving a temperature distribution accuracy of ±1°C on the roll surface, thus balancing "energy saving" and "ultra-high precision." Furthermore, the reduction in fluid flow significantly lowers equipment costs. It can operate for both heating and cooling. 【Features】 ■ Reduction of equipment costs ■ Choice of heat source ■ Prevention of condensation on cooling rolls ■ Energy-saving effect ■ Operable with set roll surface temperature For more details, please refer to the catalog or feel free to contact us.
