How It Works
- Hot hydraulic oil enters the cooler from the return line.
- Oil flows through the plate-fin core, and heat transfers to the plates and fins.
- A fan blows air across the fins, carrying the heat away.
- The cooled oil returns to the hydraulic circuit at a safe working temperature.
Applications & Aftermarket
Plate-fin aluminum hydraulic oil coolers are used on excavators, wheel loaders, bulldozers and other construction and mining machines. They are ideal for multi-brand fleets and replacement parts distributors who need reliable, cost-effective cooling at scale.
We also supply cooling for related machines: excavator coolers, CAT excavator replacement radiators and Komatsu excavator hydraulic oil coolers.
