Description:

PP-130-7489-02 CN Onan Heat Exchanger Assembly
The PP-130-7489-02CN Heat Exchanger Assembly is a marine-grade replacement component designed for Cummins Onan MDKD and MDKB series marine diesel generator sets operating with a closed-circuit (fresh-water cooled) cooling system.

This heat exchanger is responsible for transferring heat from the generator’s internal coolant loop to the raw-water circuit. Engine coolant flows through the internal tube bundle, while seawater circulates around the outer shell, efficiently removing excess heat before coolant is recirculated through the generator engine.

Maintaining stable coolant temperatures is critical for reliable generator performance, particularly during extended run times under load. A properly functioning heat exchanger helps prevent overheating, protects cylinder heads, liners, and gaskets, and contributes to consistent electrical output and extended service life in corrosive marine environments.

Manufactured to match OEM dimensions, port orientation, and mounting geometry, the 130-7489-02CN is a direct-fit replacement for the original Cummins Onan heat exchanger. Installation requires no modification to existing hoses or pipework, making it suitable for scheduled servicing, corrosion replacement, or preventative maintenance programs.
