Round Tube Plate Fin (RTPF)

HVAC Coil Coating (RTPF)

The Blygold HVAC coil coating offers remarkable, long-lasting, and resilient corrosion protection for Round Tube Plate Fin (RTPF) heat exchangers. Moreover, they effectively seal off the heat exchanger from the environment, maintaining heat transfer and minimizing pressure drop. Additionally, the system can be efficiently applied both in the factory and on-site. Furthermore, with our specialized elite products and unique application procedures, Blygold emerges as the optimal choice to prevent air conditioning failure and reduce unnecessary energy consumption due to corrosion.

Our most coveted product is PoluAl XT: an aluminium pigmented polyurethane coating developed for the protection of air-cooled heat exchangers. The product meets all the necessary requirements for the coating of RTPF condensers and coolers. PoluAl XT stands apart from the rest. It has an excellent chemical and UV resistance. It offers flexibility, excellent adhesion with negligible effect on the heat transfer. Plus it can be applied in a very thin layer, to prevent pressure drop.

This product, in combination with our unique application techniques ensures full coverage of the heat exchanger. It ensures the best corrosion protection possible. It does so flawlessly without affecting the efficiency of the heat exchanger.

Blygold has developed pioneering new coatings specifically for HVAC corrosion protection. From the very beginning Blygold has always focused on corrosion protection for heat exchangers, which are vulnerable to severe corrosion because of their construction with dissimilar metals and pollution from air circulation.

The success of these protective corrosion products derives from the unique application method including a thin layer, high UV and chemical resistance properties. These reputable products are renowned in the air conditioning business worldwide. Blygold are proud of their extraordinary success stories and our honoured to have worked on ambitious projects like the cruise ship Queen Mary 2, Palm Island Jumeirah and London Heathrow Airport.
