Shrink-Fitting System – Electrical Motors & Pumps
Induction heating system designed for fast, precise and safe shrink‑fitting of bearings, rotors, impellers, and pump components.
Seam Normalizing Systems
ENRX seam normalizing systems provide highly accurate, reliable and controllable heat treatment for longitudinally welded pipes. new generations of high-yield, thermo-mechanically processed steels require extremely precise heating profiles. ENRX addresses these challenges with advanced simulation modeling and optimized coil design that deliver accurate alloy- and gauge-specific heating and cooling zones.
The systems integrate easily into existing or new welding lines and are engineered to minimize installation length thanks to efficient air-cooling and optimized coil geometry. ENRX provides NQN and NQT technologies for full inner-wall homogenization, controlled heat-affected-zone (HAZ) coverage, and minimal outer-wall overheating.
Control systems—designed specifically for Induction—ensure precise temperature control, seam tracking using horizontal, orbital or travelling coil systems, and independent control of up to four heating stations. Advanced simulation tools (page 3) ensure optimized heat patterns across the pipe wall.
