Chemical cleaning Cooling towers

In response to
the challenges
of offline cleaning

Preventive and curative cleaning of cooling towers and their related circuits represent services with significant challenges:

  • Health and environmental challenges: controlling the risk of Legionnaire’s disease, end-to-end management of by-products, etc.
  • Legal and image-related challenges: liability and brand image in the event of contamination, relations with the Regional Board for Industry, Research and Environment, etc.
  • Technical challenges: the effectiveness of cleaning and related work, site safety, etc.
  • Economic challenges: limiting production stoppages, the performance of facilities, the longevity of equipment, etc.

  • Disinfection


Our operations are carried out by trained personnel with the necessary resources to prevent risks.
