In this area Celko Chemical has developed a complete line of multi-component products which are formulated according to the widespread demand of the market. They work through an appropriate and synergistic combination of various actives such as corrosion inhibitors, scale inhibitors, dispersing agents, microbicides, etc.

Celkron T557
Complete scale, sludge and multimetal corrosion inhibitors for hard water in cooling tower systems. High performance even in critical conditions and in presence of pollutants (oil, suspended solids, etc.). Based on special synergistic (organics+molybdenum) formula.
Celkron T561
Complete all-organic treatment for hard water in multimetal cooling tower systems. High performance even in critical conditions and in presence of pollutants (organic matter, suspended solids, etc.).

With the wide range of available chemicals, integrated in specific treatment programs, it is possible to handle any problem related with the most demanding operative conditions and with the different characteristics of the make up waters, in any cooling water systems, as for example:
  •  Once-through cooling systems
  •  Open recirculating cooling systems
  •  Closed recirculating cooling systems

Recirculating cooling
waters
Celkide K652
Organic bactericide specially recommended for anaerobic organisms (sulphur bacteria) control. Shock dosages in neutral or slightly alkaline environment. Based on organo-sulphur compounds.
Celkide K655
Broad spectrum algaecide-bactericide-fungicide organic agent. Special surface activity and surfactant properties. Based on aminic compounds.
Celkide K656
Organo-brominated bactericide for recirculating cooling systems. Shock dosages.
Celkide K657
Algaecide-bactericide-surfactant agent for slime control in recirculating water systems and for sanitization of process circuits in food industry.
Celkide K660
Broad spectrum organic microbicide specially recommended in high polluted systems, based on derivative of isothioazolone.
Celkide K663
Specific organic algaecide-fungicide for cooling tower systems and similars, both in shock dosages and in continuous use. Extremely active on some kind of filamentous algae.
Celkide K665
Broad spectrum organic bactericide-algaecide for cooling water systems; specific surface active agent, specially recommended in low retention time systems.

Recirculating cooling
waters
Celkerse X690
Polymeric wetting agent and bio-dispersant; coadjuvant of chlorination and microbicide treatment programs.
Celkerse X693
Special blend of polymeric wetting agent and dispersants both for organic and inorganic matter; used as coadjuvant in anti-scaling, chlorination and microbicide treatment programs.
Celkerse X694
Coadjuvant of chlorination; it enhances effectiveness in mineralizing organic matter by chlorine at very low level of its free residuals. It contributes to penetrate and disperse bio-amasses.
Celkide X697
Special combinations of organic microbicides with coadjuvants of chlorination; synergistic effect with halogens.
 

The innovative treatment programs allow:

  •  to minimize the corrosion rate
  •  to prevent the formation of organic and inorganic deposits
  •  to prevent microbiological proliferation and its consequences (biofouling and induced microbiological corrosion)
The above results are obtained without adversely affecting the chemical characteristics of the waste waters. This is a very important advantage for the Ecosystem, considering the large flow rates involved in such processes.
