Chiller tube end & tube sheet coating
Tube Coating That Stops Chiller Erosion and Corrosion
We deep clean, blast to a white metal finish, then apply a 100% solids epoxy to tube ends and tube sheets. On site across New England and New York.
- 100% solids epoxy bonds to corrosion-prone tube surfaces
- Push-out strength gains of over 1,000 lbs in some cases
- Free on-site estimate with project-based pricing
Over 40 years of management experience. On site in MA, NH, CT, RI, ME, VT and NY.

Why facility teams coat tubes instead of replacing equipment
Stronger tube joints
The 100% solids epoxy reinforces the tube-to-tube-sheet joint. Push-out strength has gone up by over 1,000 pounds in some cases.
Erosion and cavitation protection
Inlet-side tube ends take the worst of the water velocity. The coating protects against erosion, cavitation and further pitting.
Less downtime
Quick-cure technology means your chiller is out of service for less time. Work is scheduled around your planned outage window.
Smoother water flow
A smooth coated surface cuts inlet turbulence and fouling, helps thermal conductivity and keeps water passing cleanly.
No electrical path for galvanic corrosion
The cured film is non-conductive, so it insulates the tube sheet and helps prevent galvanic corrosion between dissimilar metals.
Prep done to white metal
Contained abrasive blasting to a white metal finish (SSPC-SP 5 / NACE No. 1) gives the coating the adhesion it needs to last.
What tube coating covers on your chiller
Tube coating is a three-step job. First we deep clean the surfaces to pull off scale, biofilm, debris and corrosion deposits. Then we blast to a white metal finish inside a containment system and rebuild any areas where metal has been lost. Last, we apply the 100% solids epoxy system to the tube ends, the tube-to-tube-sheet joints and the full tube sheet face.
The same discipline works on heat exchangers, condensers and evaporators. Most owners add the water box to the scope so it all happens in one mobilization and one outage.
- Chiller tube end coating for inlet-side erosion and cavitation damage
- Tube-to-tube-sheet joint coating to restore push-out strength
- Full tube sheet face coating with the 100% solids epoxy system
- Reconstruction of severely corroded tube sheet areas before coating
- Contained abrasive blasting to white metal, or water blasting where dry abrasive is not allowed
- Water box, end bell and nozzle coating in the same mobilization
- Shell-and-tube, plate and brazed-plate heat exchanger tube sheets
- Condenser and evaporator tube sheet and water box coating
- Zero VOC, no solvent flash-off and no shrinkage during cure
What happens after you send the form
We call you back
We ask about the equipment, the tube and tube sheet condition, access and the outage window you are working with.
Free on-site inspection
Our team comes to your site, checks the tube ends, tube sheet and water box, and confirms how much reconstruction is needed.
You get a project price
You receive project-based pricing for the scope, so you can compare it against repair or replacement and schedule the work.
Frequently asked questions
How is tube coating priced?
Pricing is project based, with a free estimate after an on-site inspection. Cost depends on chiller size, tube sheet condition, how much corrosion repair is needed, whether the water box is in scope, and access constraints.
Do you replace tubes or retube the bundle?
No. We are a coatings and surface restoration contractor. We clean, blast, rebuild corroded metal and coat. We do not sell or replace chillers, and we do not retube or replace tubes.
Where do you work?
On-site service across New England and New York: MA, NH, CT, RI, ME, VT and NY, including Boston metro, NYC and the five boroughs, Long Island and Westchester. Our office is in Franklin, NH.
How long will my chiller be down?
The coating uses quick-cure technology so downtime stays short. Work is normally scheduled during a planned outage, such as the fall or spring shoulder season. Your estimate confirms the window for your scope.
Should I coat the tube ends only?
Tube end coating is usually done together with tube sheet coating, and many owners add the water box. Combining the scope into one mobilization gives the best value and one outage instead of several.
What if the tube sheet metal is badly pitted?
Coating alone will not save a tube sheet that has lost metal. We reconstruct the severely corroded areas first to restore thickness and joint strength, then apply the protective coating system.
