Curran International’s epoxy coating solutions for HVAC chillers are engineered to protect tubesheets, waterboxes, and channels from corrosion in immersion service. These high-performance coatings create a smooth, durable barrier that reduces fouling, maintains efficiency, and withstands routine cleaning. Applied with precision, they extend chiller service life and ensure reliable operation across institutional and commercial facilities.
Chiller/HVAC tubesheet coating can provide a solution to your cooling water corrosion problems. Typical problems arise at the tube to tubesheet interface, often as a result of dissimilar metals and galvanic attack. For years Curran International has provided technicians and epoxy coating systems to repair and protect mild steel tubesheets from corrosion attacks.
Curran 500 is an advanced two part 100% solids epoxy (0 VOCs) with versatile formulations to satisfy a range of application specifications.
It can be used as a brush or roller applied liquid film, encapsulating corroded substrate with a homogeneous protective film.
Applied at an average of 50 mils DFT and the use of tube forming plugs enhances the inlet flow of cooling water while giving tubesheets years of reliable service.
The Curran 500 system has been used for all cooling water services to protect chiller tube sheets, water boxes, marine boxes, channels and circulation piping.
Provides superior protection in all water services, ensuring long-lasting performance in submerged conditions.
Excellent foul release properties with reduction in drag, improving system efficiency.
Excellent performance against cathodic disbondment, preventing coating failure in electrochemical environments.
