Belzona 1311 (Ceramic R-Metal)

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet FBC-1.


Belzona Facts:

Belzona materials allowed the application to be completed with the minimum amount of downtime; only in one shift. Belzona also provided a sacrificial coating that would ensure the blades would not deteriorate to a point where total replacement became necessary. The balance of the unit was maintained by applying an equal amount of Belzona products per blade. An additional benefit from the application was that power required to run the fan was dramatically reduced (Estimated at ± 15%).
