Magnetic inductor

currentlow-lossinductive

Overview
Roller inductors for heating rolls provide precise temperature control and uniform heat distribution for rotating heated rolls across a wide range of industrial applications. Kendrion’s modular inductors are assembled as segmented units on a shaft (heating mandrel) and inserted as a stationary assembly into the rotating roll. Typical applications include the plastics, rubber, textile, paper, film processing, metalworking, and food industries, as well as embossing, laminating, smoothing, and calender rolls.

Benefits

• Maximum energy efficiency through direct, low-loss energy transfer
• Fast and precise temperature control without delay
• Maintenance-free and low-wear operation thanks to contactless technology
• Long service life without slip rings or seals
• Flexible temperature ranges suitable for a wide variety of production processes
• Eliminates leakage risks and complex installations associated with thermal oil, water, or steam systems
• Modular design with individually controllable heating zones
• Easy machine integration through fieldbus compatibility

Applications

• Plastics and rubber industry: optimal heating and shaping of materials.
• Textile industry: efficient drying, finishing and coating processes.
• Paper and film processing: reliable drying, forming and laminating.
