COOLPAC : equipement de gestion de l'eau des tours aéroréfrigrantes

Legionella prevention

COOLPAC range is used for the water quality management of cooling tower.


  • Suitable for the most stringent requirements for cooling tower monitoring with more than 10 possible actions (measures, dosing, traceability…)
  • System ensuring continuous treatment against legionella by devolution attached to conductivity measurement or volumetric metering and treatment by temporel dosing and/or oxidizing and non-oxidant biocides regulated
  • Treatment security ensuring by automatic permutation in volumetric management in case of failure of conductivity sensors
  • Conductivity measurement by conductive or inductive conductivity sensors
  • Oxidizing biocide control available by timers and/or continuous measurement
  • Communication software : COOLPAC Surveillor for local or remote consultation and programming, data transfer, traceability and backup, data export…
  • Adaptability and flexibility
  • Biocide dosing management according to the seasons
  • Viewing of current an previous system status
