Fuel Oil Heat Exchanger Repair & Overhaul
FAA & EASA certified fuel oil heat exchanger repair and overhaul.
About the Fuel Oil Heat Exchanger
A fuel/oil heat exchanger transfers waste heat from engine lubricating oil into the fuel stream, simultaneously cooling the oil and warming fuel to prevent ice formation in the fuel system. Grouped with oil coolers in heat transfer, it is typically a compact tube-and-shell or plate matrix carrying oil through one circuit and fuel through the other, balancing oil cooling against fuel heating across the flight envelope. Because it bridges two flammable-fluid circuits, integrity is critical: dominant failure modes are internal leakage and cross-contamination between oil and fuel through cracked tubes or eroded seals, external leaks, fouling and varnish deposits that reduce effectiveness, and corrosion. Overhaul emphasizes leak and proof-pressure testing, core cleaning, and seal replacement to guarantee circuit separation and rated thermal performance.
