Siliphos Polyphosphate 20kg

R 2 914,56

SILIPHOS prevents scale and stops corrosion. It utilizes the phenomenon that minute concentrations of polyphosphates are sufficient to inhibit the deposition of scale onto metallic surfaces. Because of its phosphate and silicate content, SILIPHOS also inhibits corrosion by forming a thin protective layer on the metal surface. A SILIPHOS concentration of 2-3 ppm is sufficient to achieve both of these effects.

Siliphos Polyphosphate 20 kg – Scale & Corrosion Protection Media

Siliphos Polyphosphate is a granular scale-inhibitor and corrosion‐prevention media designed for water systems in homes, commercial buildings, and industrial plants. Additionally, it prevents scale formation and reduces corrosion by releasing polyphosphates, which form a protective, thin layer on metallic surfaces. In fact, a concentration of just 2-3 ppm is sufficient to achieve these effects.

Key Features & Benefits of Siliphos Polyphosphate

  • Scale Prevention: It inhibits the deposition of calcium and magnesium salts that cause hard water scale.
  • Corrosion Control: Because of its silicate & phosphate content, the media forms a microscopic protective layer inside pipes, helping reduce rust and “red water.”
  • Gradual Dissolution: Siliphos beads dissolve slowly over 3-6 months under normal flow, which reduces maintenance frequency.
  • Wide Compatibility: Suitable for potable water systems, reverse osmosis pre-treatment, geysers/boilers, solar hot water systems, and more.
  • Cost-Effective Protection: Helps save energy and reduces repair costs related to scale and corrosion damage.

Applications

Siliphos Polyphosphate 20 kg is ideal for:

  • Whole building water systems to protect piping, tanks, and boilers.
  • Pre-treatment upstream of RO systems to reduce scale on membranes.
  • Hot water systems, solar geysers, and heating coils.
  • Commercial establishments like hotels or hospitals need scale & corrosion prevention.

Usage Notes & Maintenance

  • Use Siliphos in a suitable dispenser or media housing on your main water line. Additionally, ensure enough flow over the beads to allow gradual release.
  • Replace or refill the media every 3-6 months, depending on water hardness and usage.
  • Avoid using in water with very low pH (below ~5) without prior correction, because acidic water may accelerate media dissolution undesirably.
  • Keep contact time sufficient; if the flow is too fast, effectiveness may drop.
