Belzona Facts
The unit was one of three identical units at this facility. Once opened, the customer was satisfied with the performance of the Belzona coating and allowed a second application on the "sister" unit. The customer also allowed for the channel boxes to be coated, and for the existing tube sheet to be coated with another layer of Belzona® 1321. This application will extend the life of both chillers for many years, and saved the customer $275,000 per unit in replacement costs.
