Blygold coatings provide long-term corrosion protection for RTPF (Round Tube Plate Fin) heat exchangers in HVAC/R systems.
The advanced coating creates a durable barrier against corrosive environments without affecting heat transfer or increasing pressure drop. Suitable for both OEM and on-site applications, Blygold coatings help prevent corrosion, improve energy efficiency, extend equipment lifespan, and reduce maintenance costs.
Blygold coatings provide outstanding long-term corrosion protection for RTPF (Round Tube Plate Fin) heat exchangers used in HVAC/R systems. The advanced coating forms a durable protective barrier that seals the heat exchanger from corrosive environments without reducing heat transfer efficiency or increasing pressure drop. The coating system can be applied both during manufacturing (OEM) and on existing equipment on-site, providing reliable protection throughout the entire lifecycle of the heat exchanger. With specialized coating technologies and proven application procedures, Blygold helps prevent corrosion-related HVAC failures, extend equipment lifespan, improve energy efficiency, and reduce maintenance costs.
For more than 50 years, Blygold has specialized exclusively in HVAC corrosion protection. Our innovative coating systems are specifically developed to protect heat exchangers from the damaging effects of corrosive environments. Corrosion mechanisms such as galvanic corrosion and pitting corrosion rapidly reduce heat transfer efficiency, leading to higher energy consumption, lower system performance, refrigerant leaks, and premature equipment failure. Blygold’s proven coating technology effectively prevents these issues while maintaining the thermal performance of the heat exchanger.
As HVAC systems continue to evolve, modern heat exchangers have become more compact and efficient through innovations such as enhanced fins, higher fin densities, adiabatic cooling systems, and microchannel heat exchangers. While these technologies improve thermal performance, they also increase the sensitivity of heat exchangers to contamination and corrosion.
Preventive corrosion protection is therefore essential to maximize the lifespan and performance of HVAC equipment. Blygold’s specialized coating systems protect vulnerable heat exchangers against aggressive environments, helping to prevent refrigerant leaks, unnecessary energy consumption, costly repairs, and premature replacement. Because modern heat exchangers feature complex geometries and require maximum heat transfer efficiency, they demand specialized coating technologies and application methods. Blygold combines decades of expertise with proven application procedures to deliver long-lasting protection without compromising system performance.
