Induction technology on track a safer, faster and better way of heating


The unrivalled accuracy, control and efficiency of induction heating makes it ideal for key tasks in the manufacture and maintenance of rolling stock and rails.

Long-distance train travel or a short commute to work on a tram or the metro is part of
daily life for millions of people around the globe. The same rails are also used to transport
animals and goods. Consequently, ensuring railway safety is vitally important, and an
integral part of this is high-quality production and maintenance of railway carriages and
rails. This is where EFD Induction comes in.

EFD Induction is a pioneer in induction heating and has expertise from almost 70 years
of servicing our customers worldwide. Our highly efficient heating equipment will ensure
improved quality of work as well as more up-time and increased output.

Compared to traditional methods of heating, induction technology is a much faster and
more efficient heating process, making it the preferred choice for lead players in the
railway industry.

Shrink-fitting tasks such as the fitting and removal of wheels and tyres or the fitting and
disassembling of bearings and lock rings can be performed quickly and easily using EFD
Induction heating equipment.

Our practical multipurpose Minac induction heater is the best on the market
and ideal for the various applications used in the railway industry. Because of its flexibility, mobility and ease-of-use, it is particularly useful to railway maintenance divisions.

Induction heating offers precise temperature control. With the Minac, an operator can
pre-set the desired ramp-up times, power delivery and dwell times, ensuring a correct heat
pattern and required temperature – and the heating cycle can be accurately repeated over
and over again. The heating is so precise it actually leaves adjacent materials unaffected,
which not only means better energy efficiency, but also safer and better working conditions.

Lock rings and bearings: The ring is heated to a completely uniform temperature and can be gently and easily removed while the shaft remains cold.

Moreover, the unmatched precision allows a gentle handling of components and there is
no damage to the heat-treated parts, which can be re-used which means less scrap and
more savings.
