Preserve Performance, Prevent Corrosion
At BMI Mechanical, we know your chillers are at the heart of your facility’s cooling system. Corrosive damage to chiller components—especially tube sheets and end bells—can lead to costly breakdowns or even a complete cooling system shutdown. Our specialty chiller coating services are designed to stop corrosion in its tracks and keep your systems running reliably.
The danger of Galvanic Corrosion in Chillers
Many chillers use copper tubes inserted into carbon steel tube sheets. This combination of dissimilar metals creates a perfect scenario for galvanic corrosion. Over time, the carbon steel begins to deteriorate, leading to:
Reduced water flow and cooling efficiency
Sediment build-up and clogging
Tube sheet perforation
Loss of refrigerant
Risk of unplanned downtime or catastrophic system failure
Left untreated, these issues can dramatically shorten the lifespan of your chiller and result in expensive emergency repairs or equipment replacement.
BMI’s Advanced Epoxy Chiller Coating solution
We help you avoid these problems with our proven, long-lasting chiller coating process:
Surface Preparation:
We begin by bead-blasting all coating surfaces to a near white metal profile, ensuring optimal adhesion and a clean foundation for the coating system.Corrosion Repair:
Any areas of corrosion or deterioration are expertly repaired to restore structural integrity and prepare the surface for coating.Epoxy Coating Application:
We apply a premium 100% epoxy solution in a three-coat system, with each coat applied at 10–15 mils for maximum durability and protection. This creates a seamless, waterproof barrier that isolates dissimilar metals, prevents further corrosion, and extends the service life of your chiller.
