Polyphosphate Ball
Product Description
Polyphosphate antiscalant balls are specialized water treatment media made from food-grade polyphosphate. They are designed to prevent scale formation and corrosion in appliances and water systems. When dissolved in water at a controlled rate, they release trace amounts of polyphosphate ions, providing long-lasting protection for household and commercial equipment.
Product Application
Uses & Benefits
Prevents limescale buildup caused by calcium and magnesium ions.
Protects heating elements, pipes, and valves from corrosion.
Extends the service life of appliances such as coffee machines, water dispensers, ice makers, boilers, and dishwashers.
Improves efficiency of machines by maintaining clean water flow paths.
Cost-effective and easy to maintain – simply replace or refill when consumed.
How Does It Work?
The balls dissolve gradually in flowing water, releasing a controlled amount of polyphosphate into the system.
Sequestration: Polyphosphate binds to calcium and magnesium ions, preventing them from crystallizing into scale.
Film Formation: A thin protective layer is formed on metal surfaces, reducing corrosion risks.
Controlled Release: The spherical shape ensures slow and stable dissolution for long-term effectiveness.
Representative Chemical Reactions:
Na2[Na4(PO3)6] + CaX → Na2[Na2Ca(PO3)6] + NaX
Na2[Na2Ca(PO3)6] + CaX → Na2[Ca2(PO3)6] + Na2X （soluble complex）
Fe(OH)2 + Na2[Ca2(PO3)6] → FeCa2(PO3)6 + NaOH (Insoluble membrane) (Magnesium ions react the same as calcium ions)

Aquavow Transparent Crystphos Polyphosphate Limescale Inhibitor Balls
Chemical Structure and Forms:
Polyphosphates from our factory Kaidefei Fluid Technology are polymers made up of repeating units of phosphate (PO4) linked together. They can be linear chains or form cyclic (ring) structures. They differ from orthophosphates, which contain only one phosphate group.
Biological Roles:
Energy Storage: Polyphosphates, particularly in the form of ATP and ADP, are vital for energy storage and transfer in cells
Cellular Processes: Involved in gene regulation, protein synthesis, and lipid metabolism.
Stress Response: Help cells cope with oxidative stress by acting as chaperones and regulating stress-response pathways.
Blood Clotting: Influence blood coagulation and inflammation.
Other Roles: Support bacterial growth, virulence, and biofilm formation.
Applications:
Water Treatment: Controls corrosion, scale, and the presence of iron and manganese in water systems.
Food Additives: Used as E452 to improve texture, moisture, and stability while reducing waste.
Flame Retardants: Incorporated in wood, paper, fabric, and plastics.
Fertilizers: Ammonium polyphosphate provides phosphorus for plants.
Research: Studies bacterial growth, virulence, and other biological processes.
The ultimate solution for protecting industrial and drinking-water systems from limescale, calcium deposits, and corrosion—delivering professional-grade performance without compromise.
💧 Key Advantages
Ultra‑high descaling efficiency (up to 98%)
Made from food‑grade raw materials and sintered at high temperature, Aquavow Crystphos inhibits scale formation by slowly releasing polyphosphate crystals that bind with calcium and magnesium ions, preventing mineral buildup and forming a protective layer.Safe and certified
Fully compliant with NSF, FDA, REACH, RoHS, CE and ISO safety standards—suitable for potable water use.Slow‑release formula with long-lasting durability
Crystphos beads remain stable until activated by water flow, minimizing waste. Lifespan of 1–2 years, with replacement every 3–12 months.
Effortless Use & Broad Compatibility
No salt, no electricity required
The transparent polyphosphate beads can be installed directly into almost any water system using a dispenser—no electrical wiring, no complex setup.Versatile application across water systems
Ideal for hot and cold circulating systems, including water heaters, boilers, underfloor heating, commercial chillers, RO systems, washing machines, and heat exchangers.Suitable for residential & industrial use
Designed for both home appliances and large‑scale commercial/industrial systems.
Cost‑Effective & Eco‑Friendly
Reduces maintenance & extends equipment life
Prevents scale and corrosion, avoids blockages, lowers repair frequency, and cuts downtime.Boosts energy efficiency
Cleaner heat exchangers and pipelines save energy and reduce carbon footprint.Backed by 20 years of R&D expertise
AquaVow has been a leader in high-performance polyphosphate scale inhibitors and water treatment solutions for two decades.
Aquavow Transparent Crystphos Polyphosphate is a food‑grade, slow‑release scale inhibitor that provides up to 98% protection against limescale, calcium deposits, and corrosion in both industrial and potable water systems. NSF, FDA, REACH, RoHS, and CE certified—safe for direct use in drinking water.
With no electricity or salt required, simply insert the transparent beads into your water system via a basic dispenser. The durable slow‑release formulation ensures long-lasting performance, requiring only 3–12 month maintenance intervals, with a total lifespan of 1–2 years.
