Alfa Marine Heat Exchangers are fabricated with the distinctive spiral corrugated tube design. Its compact structure for effective use with high fluid velocities and low-pressure drops. The tube stack is fully floating, thus minimizing thermal stresses, and it can easily be removed should cleaning be necessary. Most marine products are made of cupronickel, stainless steel 316L or titanium which are highly corrosion resistant and therefore suitable for use with seawater. Some of the smaller units are fitted with neoprene end covers which can fit directly into the seawater pipework.
