NTIC has developed the Zerust ReCAST-R solution to protect the interior surface of AST roofs, consisting of dispensers that deliver the proprietary inhibitor formulations into the vapor space between the surface of the product and tank roof. The Zerust inhibitor forms a protective layer that prevents corrosion in highly-aggressive environment (H2S, SO2, etc). Zerust ReCAST-R solution can be implemented to extend the service life of a single tank roof to 25 years and beyond. Each system is tailored to client's requirements, depending on specific environmental conditions, product stored, tank diameter, and type of metal, and can be applied on both new and existing roofs.
