HVAC Protection

Blygold coatings provide a long lasting corrosion protection for heat exchangers. They seal off the heat exchanger from the environment, without affecting heat transfer and pressure drop. The heat conductive pigmentation in the coating is oriented in such a way that it creates a very high chemical resistance at a low layer thickness. The system can be applied in the factory as well as on-site. Our specialized products, combined with our unique application procedures, make Blygold the best available option to prevent air conditioning failure and unnecessary energy consumption.

Tube Sheet

Tube sheets and water boxes are subject to severe corrosion due to the construction with dissimilar metals and corrosive water. Simply applying a coating will not prevent this due to the complexity of the construction. A special procedure must be followed to ensure the coating system will protect the valuable equipment for many years. Blygold protects tube sheets and water boxes from leakages and prevents early replacements.
