After several years of activity in the field of tightening and loosening of nuts by magnetic induction on hollow and blind-hole bolts, we have reached a higher level. Although KERA 30 was an extremely effective machine, we’ve created HELIOS-35, a more powerful, more versatile and 4.0 industry-oriented bolt magnetic induction heating machine.

The heating power of the previous versions of our magnetic induction machines was considerable and allowed to heat tie rods reduce overall process time by 80%. An outstanding result considering how slow and risky the old and obsolete resistance heating and free flame methods were. HELIOS-35 exceeds the previous versions, not only in terms of power and prompt heating, but also in terms of efficiency. Among the optionals, there is the possibility of enabling a timer to set the heating time, and facilitate the operations during consecutive loosenings.


The efficiency of HELIOS-35 goes beyond the setting of the heating time through timer. Depending on the type of application, we produce two different types of inductors. Linear inductors for tie rods and hollow bolts and annular inductors for applications on cylindrical parts in general. Given the diversity of inductors, which are custom built, this machine is equipped with a power control system so as to guarantee that each inductor can always work at its best.


It doesn’t matter if you are using linear or annular inductors. Setting the operating parameters is a breeze. Thanks to the new graphic colour display, all the setting procedures are guided and easy-to-read so that the functions of the machine can be easily managed, although we provide specific training courses to understand and make the most of the potential of our bolt induction tightening machines.

We worked on HELIOS-35 so that it can evolve with us and added the USB function through which you can update the system periodically.


HELIOS-35 is aimed at industry 4.0. In fact, it is possible to equip the machine with a connectivity package and exploit remote connection via Wi-Fi or modem. Through this function we are able to provide reports on the use of the machine to check if it is working correctly, while providing a predictive maintenance service to keep the machine working at its best. Furthermore, this feature allows us to communicate directly with the machine, so as to be able to provide direct assistance, even while the machine is operating on site, turning into reality our pay-off “near to you”.
