An interview by Gertrude MAES, journalist.

Five years ago, Shell Pernis Boilerhouse 4 was still given a lot of trouble by deposition of scale, corrosion and fouling in both the air coolers and the cooling water mains system of the air compressors. Mexel® 432 eliminated these problems. One year of testing produced positive results, and this induced Kees den Heijer, then factory co-ordinator of Boilerhouse 4, to decide to deploy the product in the air coolers of all three air compressors. Now, five years later, Boilerhouse 4 is still pleased with Mexel® 432, Den Heijer explains.
