Keep Hydraulic Oil Cool Under Load
A hydraulic oil cooler with a matched 12V or 24V cooling fan removes heat from the oil circuit of excavators, wheel loaders, tractors and other agricultural machinery. Hot oil flows through a finned aluminum core, the fan blows air across the fins, and the cooled oil returns to the tank at a safe working temperature.
We are a heavy-duty hydraulic oil cooler manufacturer - every unit is engineered to your machine's envelope, mounting space and duty, then built and tested in our own factory.
Key Features & Benefits
- Heavy-duty bar-and-plate core: vacuum-brazed aluminum core delivers maximum cooling in a compact, rugged package.
- Matched 12V / 24V fan: DC fan selected for the machine's electrical system, with thermostatic control options.
- Custom fit: mounting brackets, ports and envelope built to your machine - non-standard is our standard.
- Dust-resistant fins: designed for job-site and field conditions on construction and farm equipment.
- 100% pressure tested: every cooler tested before shipment, with test reports available.

How It Works
- Hot hydraulic oil enters the cooler from the return line or power unit.
- Oil flows through the bar-and-plate core, and heat transfers to the fins.
- The 12V or 24V fan blows air across the fins, carrying the heat away.
- The cooled oil returns to the tank at a safe working temperature.
Applications & Aftermarket
Heavy-duty hydraulic oil coolers are used on excavators, wheel loaders, bulldozers, tractors, harvesters and other construction and agricultural machinery. We also supply aftermarket replacement coolers compatible with major brands - a fast, cost-effective alternative to OEM parts, built to the original envelope and duty.
We also supply cooling for related machines: excavator coolers, bar and plate aluminum oil cooler assemblies and industrial hydraulic oil coolers.
