What to Know about Marine Oil Coolers

June 14, 2010

Seakamp Oil Coolers

Oil coolers are a type of heat exchanger which is a mechanism in a marine vessel that uses water from the lake, river or ocean to decrease the temperature of the engine’s coolant in a fresh water cooling system. Many boat owners use a mixture of distilled water and antifreeze that flows through the boat’s heat exchanger and transfers its heat to cycling raw water that is returned to the body of water in which the boat floats much like the radiator fluid in a car transfers the heat to the flowing air.

In addition, boats use oil coolers to keep the engine or transmission oil cool while on the water. Seakamp Engineering oil coolers can be used as a heat exchanger for most fluid to fluid applications. The exchanger contains all seamless tubing and can withstand pressures in excess of 800 pounds per square inch for custom high pressure applications.

Oil coolers are typically made of copper or a copper-nickel alloy called cupronickel. The alloy is resistant to corrosion in seawater, as the electrical potential force of the material is adjusted to be neutral with salt water.

Zinc anodes prevent electrolysis through the sacrificial action of zinc which does this by standing in place of the more reactive metals that comprise many boat engines. The zinc itself corrodes away rather than the metals in the heat exchanger, oil cooler or engine system itself.

Heat exchangers and oil coolers built by Seakamp Engineering can be customized to match the engine, environmental conditions, cooling requirements as well as the size and fittings of nearly any boat.
