Heat exchanger

What is a heat exchanger?

A heat exchanger is a key component of the indirect cooling system used in marine engines. It transfers heat from the engine coolant to seawater without mixing the fluids.

Why is it essential?

Unlike direct cooling, a heat exchanger protects the engine from salt and debris, ensuring efficient, reliable, and long-term cooling performance.

Available at DAM Marine

DAM Marine offers a wide range of heat exchangers for major marine engine brands like Volvo Penta, Mercruiser, OMC, Perkins and more. Each model is selected for its thermal performance and corrosion resistance.

Frequently asked questions

When should it be replaced? When leaking, inefficient or corroded.
Can it be cleaned? Yes, periodic cleaning extends its lifespan.
Is it engine-specific? Yes, it must match the engine model or be an equivalent.
