Example series shown - confirm exact fit with our engineers using your machine model or old part.

How It Works

  1. Hot hydraulic or engine oil enters the radiator from the circuit.
  2. Oil flows through the bar and plate core, and heat transfers to the fins.
  3. A fan blows air across the fins, carrying the heat away.
  4. The cooled oil returns to the circuit at a safe working temperature.

Applications & Aftermarket

Heavy-duty replacement radiators are used on excavators, wheel loaders, bulldozers and other mining and construction machines. If your original radiator is worn or discontinued, our CAT excavator radiator replacement is a fast, cost-effective alternative to OEM parts, built to the original envelope and duty.

We also supply cooling for related machines: excavator coolers, hydraulic oil coolers for Komatsu excavators and plate-fin hydraulic oil coolers.

Custom & OEM Manufacturing

Send us your machine model, drawing or duty parameters. We confirm the design and quotation within 24 hours, make a prototype for evaluation, then produce with full testing. See our custom process or contact us.

FAQ

Frequently Asked Questions

Is this radiator compatible with my Caterpillar excavator?

It is engineered as a direct aftermarket match for CAT excavators. Send us your machine model, serial number or old part to confirm the exact envelope and mounting before production.

What is a bar and plate radiator?

A bar and plate radiator uses flat plates and fins to transfer heat from hydraulic or engine oil to air, giving more strength and heat transfer than tube-and-fin designs for heavy-duty machines.

How do you test the radiators?

Every unit undergoes 100% pressure-pulse testing at our factory to guarantee zero leakage before shipment.

What is your MOQ and lead time?

MOQ is flexible for evaluation samples. Production lead time is typically 2-4 weeks depending on quantity and design.
