Water treatment for cooling circuits

We supply instruments, chemical products and specific solutions for minimising cooling process discharge (cooling towers, condensers, coolers, chillers and dry coolers). With the right ecological technologies, wastewater becomes suitable for being discharged into the sewer or to surface water.

Chemical conditioning in cooling circuits

Scale, corrosion, deposits and microbiological growth: these are some of the typical and frequent problems that come up in open or recirculating cooling circuits. Treating water correctly with these types of system protects from corrosion and prevents the formation of scale on the heat exchanger surfaces.

Designing suitable water treatments saves both water and energy, and passivates the zinc-coated surfaces of new cooling units.

Our solutions for treating cooling circuit water

Our solutions for treating cooling circuit water
Our research and development department works constantly to perfect new technologies and procedures for effective cooling circuit decontamination and maintenance.

These are some of the services we offer:

  • Preliminary analysis and periodic maintenance checks
  • Acid/alkaline washes, according to the circuit metals
  • Sanitisation against Legionella, biofilm and organic residues
  • Chemical conditioner products for the recirculated water (anti-limescale and anti-corrosion)
  • Maintenance and control of the bacterial load (biocides/ algaecides) according to the type of receiving water body (eco-compatibility at the drain)
  • Internal passivation of galvanised surfaces
  • Preparation of the biological risk exposure protocol
  • Remote system management
