Heat Exchangers and Tube Stacks

Repairs to Heat Exchangers and Tube Stacks involve:

  1. Stripping the heat exchanger, removing the tube stack, 'o' rings and gaskets

  2. Visually checking the components

  3. Replacing with new 'o' rings and gaskets, where necessary

  4. Repairing the casing of the heat exchanger, where possible

  5. Independently testing the tube stack

  6. Rod out the tube stack, where required

Fuel Tanks 

We test, clean out, repair and build new fuel tanks for many tanks found in the marine industry

Repair work on fuel tanks include:

  • Decontamination - cleaning out old solidified fuel etc. to avoid contamination of new fuel

  • Removal of debris to eliminate debris getting in to the fuel system

  • Repairing small holes to prevent fuel leaking

  • Patching larger holes

  • Making new fuel tanks using sections from the old fuel tank

  • Repairing and rebuilding fuel tanks made from most materials including stainless steel, aluminium and steel.

Radiators  

The first job is to pressure test, flow test and visually check the radiator to diagnose the problem. 

The test results will determine which of the following options are appropriate. 

​Build:

  • Build a new copper and brass replacement radiator, which is repairable if future damage occurs. Usually replaces an aluminium radiator, which is non-repairable.

Intercoolers

After testing the intercooler, the following resolutions will be considered​

​Recore / Rebuild:

  • Fit a new core

Oil Coolers

After testing the oil cooler, the following resolutions will be considered​

​Build:

  • Custom build a replacement oil cooler

See our Oil Coolers page for photos of marine oil coolers our repairers have worked on

Heaters

Heaters from the marine industry can be tested and repaired in both of our workshops. Test results will help determine which of the following options is most appropriate in resolving the heating issue.​

​Build:

  • Build a new copper and brass heater to replace an aluminium and plastic unit

Cost, longevity and time scale are important factors for the customer to consider before giving us the go-ahead to carry out any work.
