توضیحات
DHF induction bolt heaters reduce working shifts for bolt loosening and tightening. Our induction bolt heaters improve work conditions, eliminating heavy hammering, burn injury hazards and the risk of bolt damage seen in conventional methods.
Our standard heating coils are designed to prevent seizing, and highly flexible special heating coils can be inserted into a hollow bolt, even with obstructions above the bolt.
We sell induction bolt heaters and also provide on-site bolt heating services and training programs for personnel in the operation of the equipment
Principle
The high-frequency power supply flows to the heating coil and the magnetic flux occurs. The eddy current passes to the bolt and the joule heats up.
