· Technical service for fan repair and replacement

There are 5 reasons that make advisable to revise the state of your fans:

  1. Changes in the operation of the system that integrates the fan can affect its work characteritics.

  2. Blade erosion, casing or bearings wear make impossible good service.

  3. The initial design of the fan had to be modified during fabrication or installation.

  4. There is a real possibility to improve energetic efficiency by changes in the fan design, thus reducing operation costs.

  5. A reduction in maintenance expenses is needed.

Potencial problems in fan operation can be easily detected without reaching a critical situation that causes shut down of the installation.
By means of careful diagnosis our engineers check the original design and the work circumstances applying modern techniques.
Afterwards they will recommend which steps to follow in order to ameliorate the fan characteristics, adapting the fan to the actual requirements that can differ greatly from the original ones.
The rehabilitation, in case of abnormal wear or mechanical failure, as well as the replacement for other fan of better efficiency, is accomplished in the shortest time interval. We understand the critical priority of these contingencies.
As a complementary part of our work we make every possible effort to give the better service at the lowest cost in order to lengthen the future life of your fan.
