COOLPAC
Water quality management of cooling tower
The COOLPAC range has been specially designed for water quality management of cooling towers and to fight against legionella.
COOLPAC offers many assets and advantages
The PLUS for your use
Applications
- Cooling towers
Tower deconcentration management
- Volumetric (cumulative volume + purge time)
- Conductivity: graphite or inductive probe
Management of 2 biocides
- 2 types of biocides
- Biocide dosage :
– continuous
– programmable timer
– timer with regulation (oxidizing biocide)
– injection by timer, up to 16 timers - Injection cycle with pre-purging and locking
- In case of purging, injection of priority biocides
- Guaranteed biocide injection times
Management of a dispersant product and a corrosion inhibitor product
- Injection mode :
– continuous
– cyclic
– by purge time ratio
– volumetric in relation to the filling
Tower pH management
- Automatic injection by programmable pH
- Choice of regulation direction (pH+ or pH-)
