Accurate, even heat can be delivered across rotating rollers using external planar heaters or internal Inroll units. Internal heating requires a fixed centre shaft with bearings positioned outside the heated zone. Segmented heaters can be applied externally or internally when roller length or thermal zones vary.
Paper and board lines need rollers that reach temperature quickly and stay stable through speed changes. Induction keeps moisture behaviour steady and reduces variation as the web moves between stations. Laminating, packaging and printing lines benefit from a roller that delivers the same surface contact at the start of the shift as at full speed, helping you keep adhesion and coating quality consistent. Textile, fibre and food-processing setups gain controlled heating that reacts with the process, supporting sensitive materials and reducing the stops caused by slow or drifting roller temperatures.
Induction performance comes down to how cleanly the magnetic field can be guided through the system. MagComp’s Soft Magnetic Mouldable Composite is engineered for high magnetic saturation and low energy losses, helping the field stay controlled and efficient as the roller turns. This supports stable heating across different roller lengths and thermal zones. Inroll heaters place coils on a fixed centre shaft, with bearings kept outside the heated area, ensuring reliable behaviour during continuous operation and fast changes in line speed.
Yes. Induction responds at once when the web speed changes. Our proprietary magnetic material keeps the field efficient in the roller, and the control system stabilises output. That combination keeps roller temperature steady, which supports roller gap, moisture control, moisture control, adhesion and coating quality.
It depends on your roller design and process. External planar heaters suit many retrofits. Internal inroll units work when you can have a fixed centre shaft and bearings placed outside. We review your drawings, load cases and process targets, then propose the option that gives the strongest technical and commercial result.
Yes. The system reaches operating temperature quickly and holds it under load. Many customers move from slow thermal-oil ramps to fast, electric start-ups. We design the solution around your warm-up profile, so you can reach stable production faster and avoid drift between jobs.
The design is modular. We divide heaters into segments along the roller and shape the magnetic circuit for each zone. This makes it possible to handle long rollers, zoned rollers or specific compensation areas without redesigning the whole line.
It is aimed at ferromagnetic rollers in paper, board, laminating, printing, packaging, textile, fibre and food-processing lines. Typical uses include pre-heating, start-up boosting, thermal compensation and process heating during continuous operation.
Induction heats the roller directly instead of relying on hot fluid or open flames. Our unique magnetic technology keeps losses low and heat where it should be. That gives faster reaction, tighter control and a cleaner, electric setup that aligns with energy and sustainability targets.
