High wear damage to impellers results from higher fan speed and increased addition of recycling and high
abrasive material in manufacturing. The subsequent, cost-intensive repair of the impeller (demounting, repair and installation of the impeller) can be carried out mainly with our “on location service”. In case the impeller is installed, we can perform the repair by means of our special equipment. Therefore the costs of repair can be reduced enormously.
The unbalance of the impeller, which emerges from welding, is finally corrected by balancing according
to ISO NORM.
