Anti-scale sphere water filter cartridge
2-in-1 cartridge with anti-scale spheres and a sediment filter up to 100 microns.
Made from transparent material for quick monitoring of the anti-scale media level.
Proprietary design for easy replacement. Ideal for protecting domestic systems from limescale and impurities. Uses anti-scale salts that preserve water potability.
Long life, boiler!
Unprecedented protection for next-generation condensing boilers.
The chemical dosing contained in the cartridges installed inside the Sirio dosing water filters has a triple beneficial effect on the system and the devices connected to it:
- Phosphate dosing to counteract the formation of limescale deposits
- Silicate dosing for protection against corrosion
- Water filtration to retain harmful solid impurities contained in the water
Tritan™ housing
The next-generation technopolymer Tritan™ offers outstanding properties, making it ideal for demanding applications.
It provides exceptional transparency and high impact resistance, ensuring durability even under stress. With excellent resistance to pressure fluctuations and thermal stability, it withstands repeated temperature changes without degradation.
Tritan™ is also highly resistant to aggressive chemicals and maintains its clarity over time, ensuring long-lasting performance without becoming cloudy or deteriorating.
Shut-off valve with brass pin for enhanced durability (Sirio 2)
Facilitates maintenance by stopping the inlet flow, while the outlet flow is managed by a separately installed non-return valve.
A practical and durable solution for ensuring effective control of the hydraulic system.
Sirio dosing water filters and Astro dirt separators. Allies for the maximum protection of the boiler.
The Sirio polyphosphate dosing water filters are designed to work in perfect combination with the Astro dirt separators.
Together, they ensure your system is fully compliant with D.P.R. N.59 and CTI-UNI 8065 standards.
