Corroded tube sheets, end caps and water boxes often go unnoticed until it's too late. Fortunately, BIG technicians have the ability to rapidly restore these components before they cause a breakdown and loss of comfort cooling.
Over four days, BIG technicians meticulously grit-blasted rust, scale, and fouling from the corroded surfaces of two chillers, then rebuilt and protected the metal using Belzona 1341 Supermetalglide. This advanced, cold-applied epoxy coating offers long-term resistance to erosion, corrosion, and chemical attack, while also being VOC-free and safe to apply without hot work. The coating was applied in two contrasting layers (gray and blue) to ensure complete coverage and proper thickness, delivering maximum durability.
Despite challenges such as limited access on a high floor and the need for compressed air, BIG completed the work efficiently and safely. Within hours of curing, the system was back online, providing reliable cooling ahead of peak season demand.
Belzona’s high-performance materials not only halted corrosion but also extended equipment life, improved efficiency, and reduced turbulence by creating a smooth tube sheet face. This proactive repair prevented costly unplanned outages and ensured uninterrupted service for hotel guests.
By leveraging Belzona's proven polymer technology, Banks Industrial Group provided a fast, durable, and cost-effective solution that minimized disruption, safeguarded revenue, and delivered long-term HVAC asset protection.
