Induction heating system for bolt expansion
The bolt expansion solution is built around a small yet powerful mobile Minac converter and specially designed inductor coils.
Introduction
Fast, easy, accurate and repeatable heat delivery that improves productivity. Induction bolt heating is at least 70% faster than other methods. You can move it around a workshop or factory floor, change induction coils in seconds, and quickly learn how to use it.
- Mobile design with 10 m flexible connections
- Flexible – can be fitted with various coils for various bolt dimensions
- As easy to use as a regular electric drill

The ENRX bolt expansion solution is built around a small yet powerful mobile Minac converter and specially designed inductor coils.
-
Flexible: It can be fitted with various coils for various bolt dimensions. Glass fibre insulation holster, varnish lacquers and electronic coil to work-piece detection provides a triple safety on flash-over situations.
-
Simple to operate: Handheld transformers (HHT) feature on/off and precise power controls. In fact, the HHT is as easy to operate as a regular electric drill. Flexible, water-cooled cables connecting the HHT to the converter allow easy access to bolts.
-
Precise repeatability of heating cycles is assured. The same amount of energy is applied to each bolt. A constant energy level and heating time is guaranteed.
-
The use of induction heating for bolt expansion in high-pressure turbines is a powerful business tool.
-
Induction heating is a time and labour-saving alternative to inefficient flame and resistance heating for oil and gas processing plants, chemical plants and power stations.
-
An operator inserts a specially designed induction coil into the bolt.
-
The end result of a quick and safe induction bolt heating: An exposed turbine is ready for maintenance.
