We carry out full strip-down, inspection, cleaning, and repair of shell and tube heat exchangers. Tube stacks are inspected for corrosion, erosion, and fouling — damaged or blocked tubes are replaced to restore original thermal performance, with all units pressure tested before return to service.
Shell and tube heat exchangers are used across a wide range of marine and industrial engines to transfer heat between raw water and fresh water or oil circuits. Over time, tube stacks become fouled with scale, silt, and corrosion deposits that reduce thermal efficiency and can lead to overheating. In severe cases, tube failure allows raw water to contaminate the fresh water or oil circuit, causing significant engine damage.
Our overhaul process restores the heat exchanger to its original specification. We work on units from a wide range of engine manufacturers and can source replacement tube stacks and end plates for most common types.
