The Challenge
Excavators, bulldozers and wheel loaders run their hydraulic systems under heavy load all day. The pump pushes oil at high pressure, and that energy ends up as heat in the oil. Without cooling:
- Oil viscosity drops, and the machine loses power and control precision
- Seals and hoses age faster
- Pumps, valves and motors wear out sooner
- Cycle times slow down and fuel cost goes up
The Solution
An air-cooled oil cooler in the return line removes the excess heat using airflow already available on the machine. Because construction machines have no reliable water supply, the air-cooled type is the standard choice.
We run batch production of heavy-duty construction machinery hydraulic oil coolers — OEM-quality excavator oil coolers kept ready for shipment from our aluminum radiator factory, with strict QC on every batch.
We build coolers to your exact machine:
- Sized for your machine — model, oil flow, working pressure, ambient temperature and mounting space
- 12V / 24V DC fans matched to the machine's electrical system
- Dust-resistant fins for dirty job sites
- Reinforced mounting to survive vibration and shock
Why It Matters
Keeping construction machinery oil at the recommended temperature means:
- Full digging force and responsive controls all day
- Longer life for pumps, seals and hoses
- Fewer breakdowns and less downtime
- Lower fuel consumption
