simatherm IH 090

Heat smaller to medium-sized rolling bearings up to 150 kg

Product request

The compact heater for serial production

The IH 090 induction heater is suitable for heating medium to large workpieces weighing up to 150 kg. As standard, the IH 090 has a swivel arm and three yokes. Thanks to its integrated air cooling system, the IH 090 is suitable for series assembly and continuous operation.

  • For rolling bearings weighing up to 150 kg
  • For workpieces with an inner diameter of 20 to 400 mm
  • Available for voltages of 200, 400–480 and 500–575 V
  • Fan cooling for continuous operation
  • Particularly compact design - including the yokes weighing only 38 kg
  • Induction coil outside of the housing, shortens the heating times and reduces energy consumption
  • Can heat a 90 kg bearing from 20 °C to 110 °C in 20 minutes, thus saving time and energy
  • 5-stage power consumption in combination with smaller yokes, allows smaller bearings to heat up safely and quickly with less energy
  • Automatic demagnetization
  • Supplied with three yokes as standard
  • Swivel arm including yoke adapter so that swivel arm can also be used with small yokes
  • 3 year manufacturer warranty
