Used In:

  • Cooling towers
  • Auxillary water and waste water systems
  • Air washers
  • Pasteurizers/bottle warmers


  •  Ability to remove established biofilm and inhibit regrowth
  •  Broad spectrum of activity – controls aerobic and anaerobic microorganisms and algae
  •  Chemically compatible with most common scale and corrosion inhibitors and dispersants
  •  Reduces populations of sessile microorganisms known to cause corrosion and reduce heat exchange efficiency
  •  Effective over a broad pH and temperature range
  •  Non-foaming
  •  Water-soluble, so it is easy to mix into water-based formulations
  •  Effective against organisms that produce H2S, which causes corrosion and foul odors
