Marine Oil Coolers

Thermex Marine Oil Coolers have been the first choice of coolers for many marine engine and transmission manufacturers for over 30 years. The unique tube stack design manufactured by Thermex helps to prevent build up of sediments and growth from occurring within the tubes whilst minimising erosion. For vessels operating in shallow or brackish water, Thermex can also supply the Marine Oil Coolers fitted with our 70/30 CuNi tube stack or a Titanium tube stack to improve the length of operational service of the Oil Cooler. Our larger 2700 and 2800 series coolers feature leak detection rings as standard which will enable a maintenance engineer to see a leaking O Ring before the oil and water circuits mix. This feature is also available on our 2300 and 2500 series upon request.
