Oil coolers are critical for torque converter fluid circuits, dissipating heat generated during slip and torque multiplication to maintain fluid performance, prevent thermal breakdown, and protect internal components in heavy-duty transmissions and drives.
- Air Cooled (Primary): Fin tube units like EOC, AC, ACF, ACHM provide efficient, water-free cooling explicitly for torque converters and lubrication systems.
- Standard Industrial Duty: These series handle typical converter oil flows with optional bypass valves and 300°F / 300 PSI ratings — ideal for industrial and mobile torque converter applications.
- Versatile & Rugged: EOC for general torque converter cooling; AC / ACF / ACHM for standard to higher-load converter circuits.
- Applications: Off-highway equipment, marine transmissions, industrial drives, and machine tool spindle converters where fluid cooling is required.
- Torque Converter Benefits: These series prevent fluid overheating, maintain hydraulic coupling efficiency, and reduce wear — air-cooled for easy integration without water infrastructure.

Torque Converter Oil Cooling Systems
Torque converter oil coolers control fluid temperatures in power transmission circuits to maintain hydraulic coupling efficiency, prevent fluid degradation, and protect internal components during high-slip or high-load conditions.
EOC Series: — Versatile air-cooled unit with AC/DC/hydraulic fan options and standard ports — ideal for general torque converter cooling in industrial drives, marine applications, and equipment with variable duty cycles.
AC / ACF / ACHM Series: — Standard industrial air-cooled fin tube coolers (thermal capacity to 100 hp) with optional bypass relief valves — widely used for reliable torque converter oil cooling in off-highway, construction, and machine tool spindle converters.
Key Benefits
- Maintains torque converter fluid viscosity for efficient power transfer and reduced slip heat
- Prevents oxidation, varnish, and sludge buildup in the fluid
- Protects seals, bearings, and impellers from thermal wear and cavitation
- Water-free air-cooled design simplifies installation in mobile or shop environments
- Compact footprint fits on equipment skids or inside enclosures
- Computer-generated sizing for precise matching to converter heat rejection needs
