ICMS
Equinox™ Stabilizer 15 is a non-biocidal halogen stabilizing solution, designed to optimize the availability of active chlorine sources (sodium hypochlorite) in high chlorine demand, industrial process water applications. Specifically recommended for use in the paper-making industry and in industrial water cooling systems.
When used in combination with hypochlorite, Equinox™ Stabilizer 15 offers a number of benefits in handling and performance:
––
Optimizes the availability of hypochlorite for penetrating the sessile phase of the biofilm
––
Reduces potential for corrosion of equipment in the application area
––
Produces a reduction of AOX in discharge
––
Excellent compatibility with scale and corrosion inhibitors and optical brighteners
––
Reduces the consumption of sodium hypochlorite
––
Not a biocide: halogen stabilizer (stabilizes free halogens)
––
Does not require any special US DOT handling procedures or licenses
––
Reduces the pH sensitivity of halogens by expanding the pH range of active halogens.

Application Areas
Paper-making Processes
Equinox™ Stabilizer 15 is a unique product which ensures controlled availability of halogen during the paper-making process. By reducing interactions with sources of active halogen demand, Equinox™ Stabilizer 15 reduces the quantity of Sodium hypochlorite used for slime control and maximizes compatibility with sensitive process additives (including optical brighteners, retention aids, wet and dry strength aids).
Cooling Water Systems
Flexible technology: the sodium hypochlorite / Equinox™ Stabilizer 15
ratio can be adapted and optimized to define the most efficient and economical solution for each situation. Sustainability: Equinox™ Stabilizer 15 is reusable – once the product is dosed it remains within the recirculation system.
