The heat transfer tube on two evaporators had become thin-walled and, in places, through-walled.
The lead time for a replacement was sixteen weeks or alternatively remove the tubes, repair the tubes off-site and suffer from extended downtime.
The cost of traditional repairs were astronomical, almost to the point of the company considering replacing the whole unit. Lead time for both parts and replacement evaporators made this totally impractical. The company had two of these evaporators, both with the same issue.
Two collars were fabricated and prepared with power tools, bonded at each end of the tube with Belzona 1161 to give anchor points for the Belzona 1984 SuperWrap II application.
Once cured, the tube and composite sheets were wetted out with Belzona 1984 SuperWrap II and two wraps of composite sheet were applied. The application was completed in under three hours.
Alternative repair/replace solutions would have been excessively costly and resulted in extended downtime. The Belzona solution offered a speedy, in-situ repair application with long-term benefits.
