SKF TIH 220m Large Induction Heater

The SKF large induction heater TIH 220m is a reliable and robust induction heater from the SKF TIH...m range. It is suitable for heating bearings up to a maximum weight of 300 kg (660 lbs) and solid components up to a maximum weight of 150 kg (330 lbs). 

Advanced design of the power electronics including current and overheating control, combined with user friendly features such as sliding arms and remote control are standard to the TIH...m range. 

Maximum efficiency is achieved by placing the induction coil outside the heater’s housing, in the centre of the bearing,resulting in shorter heating time and lower energy consumption. 

The LED operating display and control panel are integrated in a remote control, which makes the heater easy to use. To suit different operating voltages worldwide, the TIH 220m is available in different voltage variants.
