Fuel Cooled Oil Coolers
By using aircraft fuel as the cooling medium, Fuel‑Cooled Oil Coolers (FCOCs) support efficient thermal regulation of engine and hydraulic oils in high‑temperature environments. This approach helps maintain stable oil temperatures during extreme operating conditions and warms fuel to reduce the risk of ice formation at altitude. Each unit is designed for the specific needs of the platform, balancing thermal transfer capability with size and weight targets.
