Induction Heated Jacket Rolls
High-Precision Thermal Processing Made Possible by Homegrown Technologies
Our proprietary induction heating technology enables the Jacket Roll to heat itself. The roll surface temperature is controlled within a ±0.5°C deviation by the jacket installed in the roll shell, enabling thermal processing with high accuracy.
This technology allows manufacturers to produce uniform products.
Structure of Induction Heated Jacket Rolls
Jacket chamber equalizes roll surface temperature
Thermal medium evaporates and condenses repeatedly inside the dozens of vacuumed spaces (Jacket Chambers) inside the roll shell. The roll shell absorbs and disperses the thermal energy created by these reactions, resulting in a uniform temperature on the roll surface.
A shell that heats itself
Magnetic flux occurs when an alternating current is supplied to the induction coil. This induces a current on the inside of the roll shell, and the resistance heat causes the roll shell to generate heat. High-temperature thermal energy is achieved from the direct generation of heat by the roll shell itself.
Features of Induction Heated Jacket Rolls
- POINTWide Temperature Range
Induction heating draws on the magnetic field which is produced by the electric current applied to the induction coil. This system provides high temperatures and precise control in 1℃ increments from room temperature to 800℃. - POINTUniform Surface Temperature Distribution
The heat-pipe principle maintains a uniform temperature both across and around the roll. The temperature profile remains uniform whether or not a thermal load is applied. - POINTCompact, Easy-to-Use Electrical System
Since Jacket Rolls use only electricity as their heat source, there is no need for additional facilities or special construction. The equipment requires minimal space and is easy to operate. - POINTClean, Low Maintenance Operation
Because there is no oil, vapor or combustible material to leak, the work environment stays clean and safe. The temperature control system incorporates a microcomputer. The Jacket Rolls use no ignitable substances, so operation is also safe and low maintenance. - POINTCommercial frequency specifications are not regulated by the Radio Law
The induction coil operates at commercial frequency (50/60Hz), so no inverter is required and no noise is generated. It is not regulated by the Radio Law.
