ISGEV's hot rolls are designed with an induction heating system powered by electricity and are used in the process industry in manufacturing steps such as thermoforming, 2-material lamination, coating, laminating, and finishing.
The modular solution with a dedicated power supply to each inner coil makes it possible to achieve a uniform surface temperature profile or, on the contrary, to obtain zones at different temperature to trat different materials simultaneously.
The use of electricity as the sole source of heat gives the following advantages when compared to a heating technology having internal circulation fluid:
| Absence of steam, oil, combustible material | - compact solutions (no need for fluid circulation systems, lubrication units, etc..) - safe and clean equipment - reduced maintenance - easy-to-use systems |
| Low thermal inertia | - reduced plant start-up and shut-down times, allowing for higher plant efficiency with significant time and cost savings |
| Prompt temperature variation | - the system promptly conforms to set reference temperatures and speed variations |
| Point heat generation | - possibility of setting up to 22 differentiated temperature zones - precise and uniform surface temperature distribution |
