Boiler Solution

CrestoPro B Series is a chemical with polymer base that functions to help avoid problems in the boiler, starting from scale formation, corrosion and carry-over. Meet regulations where legislation requires low or no phosphorus in the discharge water with CrestoGuard B Series solutions and maintain optimum cycles of concentration while controlling scale, corrosion and carry over.

CrestoGuard B Series provides its users with the following benefits:

  • Excellent calcium carbonate, calcium phosphate, silicate and iron oxide dispersancy, all in a single product.
  • Better deposit control than methacrylates, acrylates, and copolymer.
  • Wide application range across industries, for both online and offline system protection and system clean ups.
  • FDA approved for use in applications where steam may contact food.

Antiscalant

CrestoGuard 452 provides greater flexibility and better performance in developing multiple antiscalant programs for a variety of scales found in boiler systems, foods plants, and cleaning applications.

CrestoGuard 452 is a multifunctional product that provides formulator with:

  • Excellent calcium carbonate, calcium phosphate, silicate and iron oxide dispersancy, all in a single product.
  • Better deposit control than methacrylates, acrylates, and copolymer.
  • Wide application range across industries, for both online and offline system protection and system clean ups.
  • FDA approved for use in applications where steam may contact food.

Alkalinity Builder

Boiler water needs to be adjusted the pH to avoid corrosion due to low pH. This increase in pH also serves to support the performance of chemical descaling based on phosphate. The recommended pH depends on the working pressure of the boiler.

iGuard B408 is a liquid chemical that can increase the alkalinity of water so that it can meet the pH standard of boiler water and prevent corrosion. iGuard B408 is also a chemical that is easy to control its use and easy to control its residuals in the blowdown water so that it does not pollute the environment.

Oxygen Scavenger

Dissolved gas in water is one of the causes of corrosion in boiler systems, especially dissolved oxygen. Therefore, it is very important to be able to pay attention to the performance of the deaerator so that the dissolved gas content in water can be reduced as low as possible. The remaining dissolved gas that is still in the water can be removed by using a chemical that functions as an oxygen scavenger.

In addition, to prevent corrosion due to dissolved gas content in water, especially oxygen, which the deaerator cannot completely remove, the use of chemical oxygen scavenger is highly recommended. The use of these chemicals needs to be adjusted to the applicable boiler operating conditions. CrestoGuard 206 is an oxygen scavenger with carbohydrazide as the active ingredient and iGuard B909 is an oxygen scavenger with sodium sulfite as the active ingredient.
