Cleaning

Basic Cleaning

Mechanical cleaning is carried out using high-pressure water jetting.

This includes:

Fan blades
Internal surfaces of the cell roof
Cell walls
Internal structural components
Cooling tower basin

Chemical Cleaning

Following mechanical cleaning, a biocide is applied to relevant internal surfaces to remove biological fouling, such as algae growth.

This treatment is applied to:

Fan blades
Cell walls
Internal structural components
Internal surfaces of the cell basin
Inlet and outlet silencer louvers (where installed)

After an exposure time of approximately two hours, the biocide is removed using either high-pressure water jetting or a C-hose.

Vibrations

Imbalance and increased vibration are among the most common causes of bearing damage, premature wear, increased energy consumption and unplanned outages in cooling tower systems.

As part of our service portfolio, we offer professional vibration analysis and precise fan balancing to support reliable and efficient operation.

Our services include:

Professional vibration measurement and analysis
Early identification of root causes
Dynamic balancing of cooling tower fans
Sustainable extension of equipment service life

Inspections

Our standard cooling tower inspection includes a detailed visual and functional assessment of the main mechanical, hydraulic and structural components.

• Motor and gearbox
Inspection of the general condition, including abnormal noise, vibrations and visible damage.

• Fan and fan blades
Assessment of blade pitch settings, fastening condition and tightening torques.

• Water distribution system
Inspection of water pipes and spray nozzles for clogging, contamination, wear and damage.

• Cooling fill and drift eliminators
Evaluation of fouling, damage and correct installation.

• Cooling tower structure
Inspection for mechanical damage, corrosion and leakages.
