IVALDI bolt heaters have been specially designed to help tightening bolts on
heavy machinery. Bolt heaters are heating elements that are inserted into a hole going through the bolt and which temperature
will rise rapidly. The bolt then expands and allows further tightening of the nut. The heater is then unplugged and taken out to
allow the bolt to shrink when cooling down which results in a good tightening of the bolt.
Tailor made according to the diameter, length, wattage and voltage you require,
they can be fitted with a connecting enclosure that follows a non-heating zone together with
a handle to operate it. As an option, the heating element can be fitted with a depth stop and supply
cables can be fitted with a socket.
