Maintaining and Extending the Life of Military Aircraft
F-15 Heat Exchangers
Wall Colmonoy Aerobraze specializes in the manufacture and overhaul of Fin & Plate and Tubular Type Heat Transfer Products for F-15 Heat Exchangers.
Wall Colmonoy Aerobraze’s brazing and manufacturing expertise has resulted in increased efficiencies and significant cost savings in maintaining and extending the life of critical F-15 components for the US Air Force (USAF).
Having developed the first heat exchanger re-core procedures for the US Air Force (USAF), Wall Colmonoy has overhauled 2,500+ F-15 Tubular Type Heat Exchangers for the USAF. The overhaul process includes 100% replacement of all tubes, replacement of any non-serviceable manifold component parts, inspection and performance testing in accordance with USAF Technical Order. Original heat exchanger serial numbers are maintained for part traceability. Aerobraze achieves near 100% yield rate for the F-15 primary heat exchangers inducted for overhaul.
Since 2013 Wall Colmonoy Aerobraze has manufactured more than 500 F-15 Fin & Plate Heat Exchangers for DLA (USAF) & Foreign Military Services (FMS). Aerobraze OKC now offers an Overhaul / Re-Core workscope for the F-15 Fin & Plate Heat Exchanger.

Pioneers and Today’s Leading Experts
Wall Colmonoy developed the very first heat exchanger overhaul procedure for the US Air Force. Prior to that in the 1950s, Wall Colmonoy invented Nicrobraz® nickel-based brazing filler metal and pioneered high temperature furnace brazing. Even today, Nicrobraz® is used extensively in heat exchanger manufacture and overhaul.
Wall Colmonoy Aerobraze continues to develop its brazing and manufacturing expertise resulting in increased efficiencies, significant cost savings and performance improvements.
