OVERVIEW: The fan required pressure washing every 3-6 months to prevent large amounts of build up. This build up was causing balancing issues and unnecessary bearing load.
Chemcote was engaged to improve the efficiency of the fan, decrease problems with build up, and reduce maintenance and associated costs.

SUBSTRATE
2.8m Diameter Fabricated Steel Ventilation Fan
CHALLENGE
Prior to Chemcote’s involvement, the fan required pressure washing every 3-6 months to prevent large amounts of build up. This build up was causing balancing issues and unnecessary bearing load.
Chemcote was engaged to improve the efficiency of the fan, decrease problems with build up, and reduce maintenance and associated costs.
SOLUTION
Chemcote recommended a design which included an abrasive resistant lining to improve laminar flow with a low friction finish to reduce the amount of build up, and reduce ongoing maintenance costs.
SCOPE
Grind welds, sharp edges and remove weld spatter
Abrasive blast to class 2.5
Apply primer: RS 500P
Apply ceramic filled epoxy RP 500Balancing on coating completion and touch up
PRODUCTS
OUTCOME
The ventilation fan was inspected after its return to service at 6 months and again after 12 months. The inspections found significant improvement including reduced build up and better balance.
This system is now being used for a number of different mineral extraction facilities.
