Induction bolt heating uses induction to apply high temperatures to bolts, extending their length so the nut can be turned.
When manufacturing high-power machinery, it's necessary to tighten or loosen large-diameter bolts with high mechanical properties.
The most common method is to heat these bolts using a long electrical resistor, called a "candle," inserted into the center hole of the bolt.
This method is widely used in the assembly and disassembly of steam turbine housings and compressors.
This method is dangerous, takes much longer to perform, and poses poor worker safety.
Heating the bolts with our HELIOS 35 induction heating machine makes these operations safer and saves 10% of the time compared to using traditional electrical resistors.
The inductors used are water-cooled and remain cool when removed from the bolt, making the work safer. Inductors are available in diameters of 9, 12, 14, 16, 18, 20, 22, 24, 28, 30, 32 and 35 millimeters and can be ordered in any length.

We rent and sell these induction cookers from the Netherlands wherever you need them.
The HELIOS 35 has additional optional features, such as a timer and ring inductors for heating nuts.
