326-3898
Radiator Model 326-3898 is specifically designed for the CAT 330D Excavator. It comprises a tube-fin network, engineered to maximize heat transfer surface area. When hot compressed air flows through the core, heat transfers efficiently from the air to the tube walls.
Features
Maintains lower intake air temperatures to prevent overheating of engine components.
Higher oxygen concentration boosts combustion efficiency and improves engine performance.

How We Produce
Our aftercoolers go through advanced CAD modeling and thermal simulation to optimize airflow and cooling efficiency. We use top-tier aluminum alloy, which offers excellent thermal conductivity and corrosion resistance—key for durability. Our fin-and-tube assemblies are precision-made to maximize heat transfer surface area, while vacuum brazing ensures leak-free, strong bonding between components. Critical joints are also reinforced with TIG or MIG welding for extra reliability.
Every unit undergoes high-pressure testing and airtightness checks to ensure zero leakage. Before packaging, all components are assembled, inspected, and tested according to strict quality standards, so you can trust the final product's performance.
