Heat exchangers are essential components of many marine machinery systems, transferring heat between seawater, freshwater, lubricating oil, fuel and other operating fluids. When deposits accumulate on heat-transfer surfaces, cooling efficiency can gradually decline and machinery temperatures may increase. Our Heat Exchanger Cleaning in Lome service provides professional cleaning and inspection for vessels calling at Lome Port and anchorage.

Marine heat exchangers operate continuously and are exposed to conditions that can encourage scaling, fouling, corrosion and sediment accumulation. Even a relatively thin layer of deposits can reduce heat transfer efficiency and increase the pressure drop across the exchanger. Regular cleaning helps maintain stable operating temperatures and reduces the risk of machinery overheating.

PLATE HEAT EXCHANGER CLEANING

Plate heat exchangers are widely used for central cooling, freshwater cooling, hydraulic systems and other marine applications. Their narrow flow passages can become restricted by scale, marine deposits and foreign particles.

During servicing, the heat exchanger can be opened and the plates inspected individually. Deposits can be removed using suitable mechanical or chemical cleaning methods according to the plate material and type of contamination.

Plate surfaces are checked for corrosion, pitting, deformation and gasket deterioration. Damaged gaskets can be replaced before the exchanger is reassembled.

SHELL & TUBE HEAT EXCHANGER CLEANING

Shell and tube heat exchangers may experience fouling inside tubes and around the tube-sheet area. Seawater deposits, biological growth and scale can gradually restrict flow and reduce cooling performance.

Tube passages can be cleaned using appropriate mechanical methods, brushes, cleaning tools or approved descaling procedures. The tube bundle and surrounding components can also be inspected for corrosion, blockage and leakage.

Particular attention is given to areas where restricted seawater circulation may cause excessive machinery temperatures.

SCALE AND MARINE FOULING REMOVAL

Different types of deposits require different cleaning approaches. Hard mineral scale may require controlled descaling, while marine growth and softer deposits can often be removed mechanically.

Cleaning methods are selected according to the exchanger design, material and condition. Care is taken to avoid damaging plates, tubes, coatings or sealing surfaces during the cleaning process.

Where chemical cleaning is appropriate, the cleaning procedure can be followed by thorough flushing to remove remaining chemical residues and loosened deposits.

PRESSURE AND LEAK TESTING

After cleaning and reassembly, the heat exchanger can be checked for correct sealing and leakage. Gaskets, covers, plugs and connections are inspected before the unit is returned to operation.

Pressure testing may be carried out where required to identify leakage between separate fluid circuits. Operational checks can then confirm whether flow and temperature performance have improved.

Our Heat Exchanger Cleaning in Lome service is suitable for central coolers, freshwater coolers, lube oil coolers, fuel oil heaters, air coolers and other marine heat-transfer equipment.

For a ship calling at Lome, cleaning work can be coordinated with the vessel's maintenance schedule. Properly cleaned heat exchangers help maintain efficient cooling and stable machinery temperatures. Whether a ship is experiencing high cooling-water temperature, increased pressure drop or reduced heat-transfer performance, professional inspection and cleaning can restore the exchanger to dependable operating condition.
