How long do marine heat exchangers last?
For Diesel Marine Engines Exhaust elbows and heat exchangers should be replaced every 3 to 7 years. After-coolers and oil coolers should be inspected every 3 to 5 years. Be sure to keep a log of your last salt-water service (3 to 5 years most typically) Be sure to keep a log of your last exhaust elbow inspection.

What are marine heat exchangers made of?
Aluminium brass is generally used for the construction of the tubes which is 76% copper; 22% zinc and 2% aluminium. Sacrificial anodes are used in the seawater side for corrosion prevention as they corrode first and prevent the material with seawater being the electrolyte.Oct 18, 2021
How much does it cost to make a heat exchanger?
