Custom Surface Air-Cooled Oil Coolers for Demanding Engine Applications
At AMETEK Hughes-Treitler, we specialize in designing and manufacturing custom Surface Air-Cooled Oil Coolers (SACOCs) for a wide range of engine platforms, including commercial jets, military aircraft, and UAVs.
Our SACOCs are built with lightweight aluminum plate-fin construction and are engineered to fit seamlessly within engine cowlings and ducts. This design maximizes surface area and airflow, delivering efficient cooling in even the most compact and complex environments.
From small business jets to large commercial engines, our coolers wrap around the engine’s circumference to provide reliable thermal management when space and performance matter most.
Optimized for High Performance
Our Surface Air-Cooled Oil Coolers are built to perform in the most demanding environments where thermal efficiency, lightweight design, vibration resistance, and pressure durability are critical. We prioritize reliability and decongealing performance to ensure continuous, long-term operation of high-performance engines without interruption.
