Belzona Facts
The customer had tried several materials previously on these heat exchangers and because of the severely corrosive and elevated temperature service conditions, none had lasted more than a year or two. Belzona 1593 is designed for permanent immersion conditions up to 160°C and so it was the ideal coating to protect all parts of this asset.
