Belzona Facts
The plant could not run without a `new' water box. The only other solution was to literally replace the whole box and tube bundle.This would have taken six months and cost over $3 million. The Belzona Solution allowed the utility to begin producing power for the lucrative market within days. Exterior condensation problems have also been solved.
