111-5059
Radiator Model 111-5059 is specifically designed for the CAT 3508B Mining Loader. It primarily works to cool down compressed air from the turbocharger or supercharger—doing so before the air enters the engine's combustion chambers, which directly supports stable engine operation.
Features
Built to efficiently reduce compressed air temperature: laying the foundation for stable equipment performance.
Smart finned design: Cooling fins expand heat dissipation surface area, accelerating heat release and boosting overall cooling effectiveness.

Maintance and Service
Customized Cooling – Solutions built to align with your engine's demands and unique working environment characteristics.
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.
