Cool Industrial Hydraulic Systems That Run Hot
An industrial hydraulic oil cooler with a cooling fan and flange connection removes heat from hydraulic power units (HPUs), presses, injection moulding machines and machine tools. Hot oil flows through a finned aluminum core, the fan blows air across the fins, and the cooled oil returns to the circuit at a safe working temperature.
We are a hydraulic oil cooler manufacturer - every unit is engineered to your flow rate, heat load and flange standard, then built and tested in our own factory.
Key Features & Benefits
- Fan + flange in one assembly: complete, ready-to-mount unit for industrial hydraulic systems.
- SAE / DIN flanged ports: reliable high-pressure connections, or threaded/custom manifolds.
- Vacuum-brazed core: clean, strong, leak-free joints for long service life.
- Heavy-duty construction: built for continuous industrial duty.
- 100% pressure tested: every cooler tested before shipment, with test reports available.

| Fan voltage | 12V / 24V DC, 110V / 220V / 380V AC |
| Connections | SAE / DIN flanges, threaded or custom |
| Core type | Vacuum-brazed aluminum bar-and-plate |
How It Works
- Hot hydraulic oil enters the cooler through the flange connection.
- Oil flows through the bar-and-plate core, and heat transfers to the fins.
- The fan blows air across the fins, carrying the heat away.
- The cooled oil returns to the power unit through the outlet flange.
Applications & Aftermarket
Industrial hydraulic oil coolers are used on hydraulic power units, presses, machine tools, test rigs and lubrication systems. The flanged design suits high-pressure circuits where threaded fittings are not enough.
We also supply cooling for related machines: heavy-duty hydraulic oil coolers, bar and plate aluminum oil cooler assemblies and industrial machinery applications.
