What Is Evolet Anti‑Scale Media?

Evolet anti-scale media uses a patented catalytic process to convert dissolved calcium and magnesium (hardness) into micro-crystals that remain suspended in the water. Unlike a water softener, Evolet anti-scale media does not remove the hardness minerals — it simply prevents them from forming sticky scale that clogs pipes or damages appliances. The Water Company

Because the media creates a “template” on its surface, it encourages stable crystal formation, which does not adhere to surfaces or plumbing fixtures. Rotea Australia

Key Features

• No salt, chemicals, or electricity needed.
• Long service life — the media does not require regeneration or backwashing.
• Upflow contact design maximises scale control efficiency.
• Maintains mineral content in water — calcium and magnesium remain in solution.
• Certified: WQA Gold Seal, tested for material safety.
• Nanostructured surface lowers the energy needed for crystal formation.

Benefits

1. Scale Prevention: Transforms hardness ions into stable micro-crystals, preventing scale deposit buildup.
2. Eco-Friendly: Since there’s no salt or chemical added, the media is more sustainable than traditional softeners.
3. Cost Saving: Without the need for regeneration, you save on salt, water, and maintenance.
4. Protects Appliances: Helps prevent scale in geysers, boilers, kettles, and plumbing.
5. Simple Operation: No power or backwash makes the system easy to maintain.

Ideal Applications

• Home plumbing systems (to protect pipes and water heaters)
• RO feed water (to reduce scale risk on membranes)
• Boiler systems and heat exchangers
• Aquaculture and industrial processes where scale buildup is costly
• Appliances such as kettles, coffee machines, or shower systems

How to Use / Install

• Install Evolet anti‑scale media in an appropriate media vessel or cartridge housing.
• Ensure an upflow water direction to maximise contact with the media.
• No regeneration needed — simply replace media when contact capacity is exhausted (based on manufacturer guidance).
• Check periodically for media condition, especially in high-hardness environments.

Safety & Maintenance

• Since it’s a non-chemical solution, Evolet media does not leach dangerous substances into drinking water.
• Store media in a dry place to avoid contamination before use.
• Flush the system after installation to remove any loose particles.

Physical Properties & Operational Conditions of Evolet Anti‑Scale Media

Based on the SC3 Evolet Media specification sheet from Rotek / RoteK Australia: Rotea Australia

• Bulk Weight / Density: ~ 750 kg/m³.
• Specific Surface Area: ~ 270 m²/g.
• Colour: Light yellow.
• Mesh Size / Particle Size: 0.5–0.8 mm.
• Moisture Content: ~ 24–28%.
• Freeboard (Up‑Flow): 60–70%. (Freeboard is the portion of the vessel not filled with media, allowing for expansion/contact)
• Operating Temperature Range: 5 °C to 70 °C.
• pH Range: 6‑9 (for effective operation, according to spec sheet).
• Volume Change in Water: Maximum ~ 60%. (This presumably refers to expansion or swelling when the media is in contact with water.)
• Media Lifetime: 2–3 years (as stated in the spec sheet) under normal usage.

“Exchange Capacity” / Scale-Crystallization Function

• Unlike traditional ion-exchange resins, Evolet doesn’t “exchange” ions in the sense of swapping Ca²⁺ or Mg²⁺ for Na⁺. Instead, it promotes the formation of stable micro-crystals of calcium and magnesium (hardness minerals), which remain suspended rather than forming scale that adheres to surfaces. Rotea Australia
• The media acts as a template: hardness minerals crystallize on the surface of the media, but once they reach a certain size, these particles detach and remain in the water as harmless, stable crystals. Rotea Australia
• Because of this mechanism, there is no classical “ion exchange capacity” (meq/g) listed — instead, the capacity is more about how much scale-precipitable hardness it can manage over time. The spec sheet does not provide a direct “exchange capacity” in meq/L.
