Finned tube heat exchangers are widely used in demanding industries such as power generation, offshore, petrochemical, and heavy processing.
In harsh operating environments, they require effective corrosion protection to maintain heat transfer efficiency, prevent premature failure, and extend equipment lifespan. Blygold’s specialized coating systems provide long-lasting protection without compromising thermal performance.
Blygold coating systems for finned tube heat exchangers are specifically developed to provide long-term corrosion protection for L-foot, embedded, and extruded fin tubes while preserving their thermal performance. The coatings can be applied to individual finned tubes before bundle assembly or to fully assembled tube bundles. Using Blygold’s proprietary spray application technology, complete and uniform coverage is achieved, even in densely packed and difficult-to-access areas of the tube bundle.
Extensive laboratory and field testing has demonstrated that Blygold coatings have a negligible impact on heat transfer and pressure drop while providing outstanding resistance to corrosion, UV exposure, and aggressive chemical environments. This enables finned tube heat exchangers to maintain their thermal efficiency, reduce maintenance requirements, and significantly extend equipment lifespan.
Even in the most demanding industrial applications, including heat recovery systems operating in high-temperature exhaust gas streams, Blygold coatings deliver reliable long-term protection. They effectively protect aluminium fins and other vulnerable components against premature corrosion, helping to maximize equipment reliability, improve energy efficiency, and reduce lifecycle costs.
Blygold PoluAl XT is our flagship aluminium-pigmented polyurethane heat exchanger coating, specifically developed to provide long-term corrosion protection for air-cooled RTPF (Round Tube Plate Fin) heat exchangers in HVAC/R systems. The coating is engineered to meet the demanding performance requirements of condensers and cooling coils operating in corrosive environments.
PoluAl XT offers outstanding chemical and UV resistance, excellent flexibility, and superior adhesion while maintaining optimal heat transfer. Its ultra-thin coating film minimizes air pressure drop and preserves the original performance and energy efficiency of the heat exchanger.
Combined with Blygold’s proven application techniques, PoluAl XT ensures complete and uniform coverage of the heat exchanger, delivering maximum corrosion protection, extended equipment lifespan, reduced maintenance costs, and reliable long-term HVAC/R performance.
Blygold PoluAl High Temp is a thermally conductive, corrosion-resistant coating specifically developed to protect heat exchangers and metal surfaces operating under extreme temperatures. The coating withstands continuous temperatures of up to 550°C (1022°F) while providing long-term corrosion protection against aggressive environments and high-temperature degradation.
By preventing corrosion-related capacity loss and premature deterioration, Blygold PoluAl High Temp helps maintain heat transfer efficiency, maximize heat recovery, and extend the service life of high-temperature heat exchangers. Applied by qualified Blygold specialists using proven application techniques, the coating delivers reliable long-term performance, improved equipment reliability, and reduced maintenance requirements, even in the harshest industrial environments.
Blygold offers a comprehensive range of protective coating systems tailored to the specific requirements of every application. Our products are developed to deliver long-term corrosion protection for HVAC/R heat exchangers, combining outstanding performance with energy efficiency and low lifecycle costs. The portfolio includes both solvent-based and VOC-free, water-based coatings, providing sustainable solutions for a wide range of operating environments and customer requirements.
