Heavy-Duty Water Radiator for Komatsu HD785 Mining Truck

The Komatsu HD785 is one of the most widely used rigid dump trucks in large-scale mining and quarry operations. Its high engine output and demanding workload require an equally robust cooling system to ensure operational stability and engine longevity. SINRUI's model PC2169 water radiator is a heavy-duty cooling solution designed for the Komatsu HD785.It can serve as a direct OEM-fit or a reliable aftermarket replacement.The unit is built to handle harsh mining environments and withstand extreme thermal loads.

Radiator Structure and Materials

The PC2169 radiator features a core structure made of seamless copper tubes and fins.This design is optimized for excellent thermal efficiency and long-term durability.It also provides strong resistance to clogging, especially in dusty mining environments.

·Core Type: Tube-fin structure

·Tube Material: High-purity seamless copper 

·Fin Type: Corrugated copper fins, anti-corrosion coated

·Frame: Carbon steel or stainless steel (customizable)

·Mounting Type: Bolt-on with shock-absorbing brackets

The copper tubes provide excellent heat conductivity, while fins maximize heat dissipation with minimal airflow resistance. The brazed core design ensures a leak-proof, high-strength bond that resists vibration and thermal fatigue.

Complete Kit and Replacement Compatibility

The radiator is available as a complete replacement kit, including:

·Radiator core

·Inlet/outlet headers

·Mounting flanges
