Unicount Koax Light (Art. No. A21900-001-000)

Reference: A21900-001-000 | The Universal Solution for Apartment Water Metering | Swiss Quality Standard

The Unicount Koax Light is the "universal solution" for apartment water metering systems. This unit is a simple solution without casing (gainage), specifically designed for installation in technical cabinets, module systems, prefabricated constructions, and dry construction.

Logical Workflow & Rough-in Neutrality

The system provides project owners and installers with maximum flexibility, ensuring total neutrality during the early stages of construction.

• Neutrality in the Shell Phase: The system remains neutral during the shell construction phase, allowing for later technological decisions.
• Freedom of Choice: The brand of measuring capsules, reading technology (Radio or M-Bus), and service provider can be selected or changed at any time after the building is finished.

Robust Monobloc Construction

A streamlined engineering approach that simplifies the installation process and enhances structural integrity.

• Single-Piece Casting: The shut-off valve and the Koax body are cast as a single monobloc piece.
• Installation Efficiency: This design eliminates the need for additional adapter rings or bypass pieces, making the assembly faster and more reliable.
• Universal Compatibility: Equipped with neutral G 3/4" interfaces, it is compatible with all standard piping and distribution systems.

Low Maintenance & High Technical Standards

High-quality materials and accessible design ensure a long-lasting and quiet hydraulic system.

• Stainless Steel Seat: The DN 3/4 straight-through valve features a wear-resistant (erosion-resistant) seat made of stainless steel for extended service life.
• Easy Operation: Both the meter and shut-off valves are easily accessible and can be operated using a standard Phillips screwdriver.
• Certified Performance: Meets Acoustic Group I requirements (ISO 3822) for quiet operation and offers pressure resistance of at least 25 bar (SN EN 1213).
• Modular Interchangeability: Supports all brands of 2-inch KOAX measuring capsules (Qn 1.5 m³/h), which can be replaced or upgraded at any time.

Product Note: This article is delivered in a raw finish (000) and includes 2 pressure test covers, 2 3/4" caps, 2 mounting brackets, and 4 noise insulation sleeves. Screws and measuring capsules are not included.

Expert Perspective: The Unicount Koax Light acts as a universal chassis for your water system, providing a robust mechanical base that remains open to any future technological "updates."
