Roller inductors for heating rolls

Our inductors for heating rolls and other heated rotating rolls – for example in calenders – ensure precise temperature control and even heat distribution in a wide range of industrial applications.

Modularly designed individual inductors allow individually controllable heating zones to be created. These segments are mounted on a shaft to form a heating mandrel and inserted into the rotating heating roller as a stationary unit. In addition to the heating roll, the inductors are used in other heating systems such as base cylinders, embossing cylinders, current conductive rolls, smoothing rolls, chill roll cylinders, laminating rolls, and calender rolls.

Whether for the plastics and rubber industry, textile production, paper and packaging processing, metalworking or the food industry – we offer you the right solution.

Maximum efficiency, minimum maintenance – with inductively heated heating rolls

Unlike conventional heating rolls, which use thermal oil, water, or steam, inductive heating requires neither complex installations nor costly approval procedures. Leakage risks and liquid media are a thing of the past – protecting the environment and health while reducing operating costs.

Inductively heated heating rolls with our application-specific inductors offer decisive advantages over classic heating rolls with heating rods or liquid media:

• Maximum energy efficiency through direct, low-loss energy transfer

• Fast and precise temperature control without delay

• Maintenance-free and low-wear – no slip rings or seals

• Long service life thanks to contactless technology

• Flexible temperature range for a wide variety of production processes

Thanks to our specially adapted, fieldbus-compatible induction generators, integration into your machine is quick and easy. On request, we can also supply the heating rolls as a completely autonomous unit with integrated control and operating display.
