Fast and efficient heating of bearings

Heating a 210 kg bearing from 20º C to 110º C now only takes 20 minutes thanks to SKF's new TIH 210m induction heater. Designed to enhance plant productivity and efficiency, the new induction heater reduces heating time and power consumption by up to 30% and can cut heating costs in half. To further promote low energy consumption, the induction heater uses a relatively low power input of 10kVA.

The SKF TIH 210m has been introduced along with the TIH 070m and TIH 090m, which give similar time and cost savings in heating small and medium sized bearings. The TIH 070m has a maximum heating capacity of 80 kg. The TIH 090m has a heating capacity of 120 kg.

The incredibly fast heating speed is achieved by positioning the induction coil outside the heater's housing, allowing the bearing to be placed around the coil. Additionally, the heaters demagnetise the bearings after they have been heated.

Previous induction heaters were hindered by a belief that there was a correlation between a high kVA and better performance, in terms of heating time and capacity. However, a high kVA generally only leads to higher power consumption and not necessarily better performance. The new induction heaters demonstrate that a relatively low power input of 10 KVA leads to low energy consumption and better performance.

All the induction heaters are available in one power supply execution ranging from 400V/50Hz to 460V/60Hz. When plugged-in, the heaters detect the power supply and automatically adjust their voltage accordingly.
