Manifold - fitted with control flow meters - 1 "xEK; 12-way; brass IVAR.CI 553 VP

Product detailed description

Manifolds with integrated control flow meters are essential components in hydronic heating systems, particularly in underfloor heating applications. They allow for precise flow regulation across multiple circuits, ensuring even heat distribution. This 12-way model is suitable for residential and commercial buildings where zoning and thermal efficiency are critical. Installers working on combined floor and radiator heating systems must ensure proper system flushing and maintenance to avoid blockages and inefficiencies.

When installing this manifold, the system designer should consider the hydraulic balance and the need for accurate flow measurement in each circuit. The brass construction provides durability and resistance to corrosion, making it suitable for long-term operation in closed heating systems. The 50 mm outlet spacing allows for compact installation in standard wall or floor-mounted enclosures.

The operating temperature of +90°C and PN 10 pressure rating are key factors in determining the suitability of this manifold for underfloor heating systems. The flow meters have a regulation range of 0÷5 l/min, which is appropriate for low-flow applications. The material, brass CW617N, ensures compatibility with standard heating media and long-term mechanical stability.

Installation and connection

The manifold features side inlets with 1" F connections and 12 outlets with 3/4" EK threads. The 50 mm spacing between outlets allows for standard pipe routing and connection to individual heating loops. Installers must ensure that all connections are tightened to the manufacturer's specifications and that the system is flushed before commissioning to remove any debris. Common installation errors include incorrect orientation of the flow meters and failure to align the manifold with the heating circuits, which can lead to uneven flow distribution.

Compatibility and accessories

This manifold is designed for use with underfloor heating systems and is compatible with standard heating circuits using 3/4" EK connections. Additional components such as insulation, mounting brackets and balancing valves may be required depending on the system design. The manufacturer recommends using the GEL.LONG LIFE 100 preparation to protect the system from corrosion and contamination.

Technical background for designers

The manifold operates by dividing the incoming water flow into 12 individual circuits, each equipped with a control flow meter. The brass CW617N body provides good thermal conductivity and resistance to mechanical stress. The flow meters allow for manual adjustment of flow rates to ensure balanced heat distribution. The integration of this manifold into the system depends on the overall hydraulic design, including pump capacity and pipe sizing. The service life and efficiency are influenced by the quality of the system water and the regularity of maintenance procedures.

Service and operation

Regular system flushing is essential to prevent blockages and ensure the long-term performance of the flow meters. The manufacturer recommends a thorough flush before commissioning and periodic checks during operation. No specific service intervals are provided, but any signs of reduced flow or uneven heating should prompt an inspection of the manifold and associated components.
