EDDYTHERM 4x is a powerful induction heater suitable for workpieces up to 300 kg.
The swivel-arm crossbar design and the pedal-operated crossbar lift allows a one-man operation even when mounting extremely large workpieces, while the heavy, welded-steel carriage provides on-site mobility.
EDDYTHERM 4x controls the heating by continuously monitoring the workpiece temperature and adjusting its own heating power accordingly. This ensures that the workpiece is heated evenly and the selected temperature is achieved precisely. The crossbar itself remains cool to the touch.
EDDYTHERM® utilizes the induction principle as in transformers – its core and windings can be seen as the primary side, but the workpiece acts as a short-circuited secondary winding, which rapidly heats up due to its great electrical resistance. This phenomenon allows EDDYTHERM® to control heating by continuously monitoring the workpiece temperature and adjusting its own heating power accordingly. This ensures that the workpiece is heated evenly and the selected temperature is achieved precisely. The crossbar itself remains cool to touch.
Why shrink fitting?
Proper shrink fitting extends the life of roller bearings by several times. Nearly half of all reduced bearing life expectancy is due to improper installation. Mechanical methods such as hammers and hydraulic presses risk damaging the inside surface of the inner ring and the bearing races. The better shrink fitting solution is via induction heating.
