Today on the show, we welcome Chris Nagle. Chris has a background in water treatment and today works at Evapco, one of the largest cooling tower manufacturers in the world. Have you ever heard the term white rust? It is a problem that many water treaters face and is the topic of this episode today. In a nutshell, white rust is the galvanizing coming off of a cooling tower. Galvanizing is a coating of zinc over the steal surface, which is done so that the zinc corrodes instead of the steel below it. White rust is the premature corroding of that zinc and this is a serious problem, one that it often blamed on the water treater.
Evapco have been doing an amazing job at teaming up to gather and share information on white rust and how we can help solve this issue in new ways, together. Chris has a unique perspective and a wealth of insight on the topic of white rust and today, he explains the process of galvanizing and passivation and the challenges white rust has placed on the industry today. Chris shares some of the fascinating things Evapco are doing to help solve this issue and provides some great advice for water treaters on how to prevent and manage white rust.
