Cooling Tower Maintenance

Routine maintenance helps identify and resolve small issues before they become major breakdowns. Most checks can be carried out while the cooling tower is in operation, minimising disruption.

Typical maintenance tasks include:

  • Inspecting fan blades, motors, and inlet louvres
  • Checking for leaks and even water distribution
  • Ensuring no excessive drift loss
  • Cleaning basins and strainers as needed

Regular inspections safeguard your cooling tower, extend its service life, and maintain efficient performance.

Cooling Tower Servicing

Comprehensive servicing is carried out periodically to restore the cooling tower to peak condition. It typically involves cleaning, replacing internal components, and repairing mechanical parts, often during planned plant shutdowns.

Our servicing process may include:

  • Replacing worn components such as motors, impellers, and float valves
  • Cleaning or replacing fill, drift eliminators, and louvre inserts
  • Repairing distribution pipes, fan guards, and mechanical supports
  • Removing scale, sludge, and debris from basins and nozzles

Service intervals are determined by operating conditions but are generally quarterly, bi-annual, or annual.

Cooling Tower Components / Spares

We offer a comprehensive range of spares and accessories for all cooling tower types, including fills, motors, drives and nozzles.

Heat Exchanger Maintenance

Regular maintenance is essential to preserve heat transfer efficiency and prevent unplanned downtime. Establishing a planned maintenance schedule ensures early detection of wear, fouling, or leaks before they impact performance.

Typical maintenance activities include:

  • Inspecting plates and gaskets for wear or corrosion
  • Checking for leaks and uneven temperature differentials
  • Monitoring operating pressures and flow rates
  • Flushing or cleaning to remove scale and debris

Regular inspections safeguard your cooling tower, extend its service life, and maintain efficient performance.

Heat Exchanger Servicing

When cleaning or component replacement is required, our technicians perform comprehensive servicing to restore your heat exchanger to optimal condition.

This may include:

  • Dismantling and inspecting the plate pack
  • Chemical or mechanical cleaning of plates and frames
  • Replacing gaskets, seals, or damaged plates
  • Pressure and leak testing to ensure integrity

Service intervals depend on the application and water quality but are generally recommended on a quarterly, bi-annual, or annual basis.

Legionella Disease Prevention Measures

Legionella bacteria thrive in warm, stagnant, or poorly maintained water systems, posing a risk of Legionnaires’ disease. Cooling towers often provide ideal conditions for bacterial growth, which is why preventive measures are essential.

Recommended strategies include:

  • Good servicing and maintenance of your cooling tower
  • Regular water treatment
  • Routine cleaning and inspection
  • Water quality monitoring
  • Minimising dead zones and stagnant water areas to ensure effective circulation
