MTU 12V4000 G21
The MTU 16V4000 G21 Radiator is a cooling system component, typically water-cooled and often using a dual-loop configuration, that manages the significant heat generated by the 16V4000 diesel engine. These radiators are precision-engineered for continuous duty in applications like industrial power plants, hospitals, and data centers, and they include features such as a heavy-duty steel frame and a copper tube core.
Features
Separates cooling for the engine's jacket water and aftercooler, managing two distinct thermal loads.
Built with a steel frame and a copper tube core to withstand harsh operating environments.
Designed with an optimized core and fan for high-efficiency cooling required for continuous duty power generation.
