EUROCET W300 organic corrosion inhibitor

Article : EPUROW300
  • Prevents scaling and corrosion  ?
  • Increases the water pH to 9.0-9.5  ?
  • Easy dosage control  ?

EPUROCET W300 is an organic product that prevents scale formation and corrosion by creating a protective film, used for hot water boilers, closed cooling systems and cooling systems. The polyamines contained in EPUROCET W300 create a protective film on the metal surface that is an impermeable barrier between dissolved oxygen and the metal surface thus preventing oxygen corrosion.

The film-forming amines contained in EPUROCET W300 alter the crystal structure of calcium carbonate to form an easily removable precipitate.

Scale formation decrease due to the presence of copolymers.

Key advantages:

  • Effective corrosion and sedimentation inhibitor

  • Complex action organic product

  • Raises the pH of the boiler water to 9.0...9.5

  • Easy dosage control over pH

Polyamines are effective due to the formation of a monomolecular layer on the surface of the metal, creating a barrier between water and the metal surface: the diffusion of dissolved oxygen in the water, and corrosion through this film is reduced by 90%. Copper pipes protected due to the presence of a special corrosion inhibitor.

The presence of both film-forming and neutralizing amines causes complex treatment of water.

Neutralizing amines bind free carbon dioxide and help maintain the required pH, increasing the effectiveness of film-forming amines.

EPUROCET W300 quantity dosed depends on many parameters (such as temperature, total hardness, etc.). A typical dose is 1 liter per 1 m3.
At the start EPUROCET W300 must be entered directly into the flow. Processing of the feed water can be performed by an automatic dispensing system in proportion to water consumption.

The parts of the dispensing devices contacting the product must be made of alkali-resistant materials (PVC, PE, etc.). The material Viton should be avoided. EPUROCET W300 should be dosed undiluted.

The EPUROCET W300 content can be determined from the concentration of film-forming amines by titration or photometry. The minimum residual concentration of polyamines should be maintained at a level of 2 g/m3.

EPUROCET W300 effectiveness dosage should be checked additionally by measuring the pH. The pH should be between 9.0 and 9.5.
