Manifold - fitted with control flow meters - 1 "xEK; 3-way; brass IVAR.CI 553 VP

Product detailed description

Three-way manifolds with integrated flow meters are essential components in hydronic heating systems, particularly in underfloor heating applications. These manifolds allow for the distribution and regulation of heated water to multiple zones. Installers working in residential or commercial buildings often use such manifolds to ensure balanced flow distribution and precise temperature control. The integration of control flow meters ensures each circuit receives the correct flow rate, which is critical for system efficiency and occupant comfort.

When installing in systems with combined underfloor and radiator heating, careful attention is required to system balancing and flushing. The presence of flow meters simplifies this process by providing visual feedback on flow rates, aiding in the fine-tuning of the system. The brass construction of the manifold ensures resistance to corrosion and long-term reliability in wet environments.

The operating temperature of +90°C and nominal pressure of PN 10 define the conditions under which this manifold is suitable for installation. These parameters are crucial for determining compatibility with the rest of the heating system components, such as pumps, valves, and piping. The brass material (CW617N) is selected for its mechanical strength and resistance to thermal expansion, making it suitable for long-term use in heating systems.

Installation and connection

The manifold is equipped with side inlets of 1 inch female thread and three outlets of 3/4 inch external thread. The spacing between the outlets is 50 mm, which must be considered when planning the layout of the manifold within the system. During installation, it is essential to ensure that all connections are tightened to the correct torque to prevent leaks. A common mistake is neglecting to clean the internal system before commissioning, which can lead to blockages in the flow meters or valves. Always verify the thread type and direction of flow to avoid misalignment with the rest of the system.

Compatibility and accessories

This manifold is compatible with standard underfloor heating systems using 3/4 inch external thread connections. To complete the system, additional components such as balancing valves, insulation, and mounting brackets may be required. The use of a system purging compound is recommended to ensure the system is free from debris before operation. No specific related products are listed for this model, but it is typically used in conjunction with other IVAR heating system components.

Technical background for designers

The manifold operates by dividing the incoming water flow into three separate circuits, each equipped with a control flow meter. The flow meters allow for the adjustment of flow rates within the range of 0 to 5 l/min, ensuring each circuit receives the correct amount of heat. The CW617N brass alloy is chosen for its high strength, corrosion resistance, and thermal conductivity. The design of the manifold ensures minimal pressure loss and even flow distribution. The integration of the flow meters into the manifold body reduces the need for additional components, streamlining the installation process and reducing potential leak points.

Service and operation

Regular inspection of the flow meters is recommended to ensure they remain free from debris and operate within the specified range. The manufacturer advises a thorough system flush before commissioning, especially when combining underfloor and radiator heating. No specific service intervals are provided in the brief, but the system should be monitored for any signs of blockage or irregular flow. If irregularities occur, the system should be flushed again following the manufacturer's guidelines.

Frequently asked questions

Can this manifold be used in a system with both underfloor and radiator heating?
Yes, the manifold is suitable for such systems. However, the manufacturer strongly recommends a thorough system flush before commissioning to prevent blockages.

What is the maximum operating temperature of the manifold?
The maximum operating temperature is +90°C, which is suitable for most underfloor heating applications.

What is the material of the manifold body?
The body is made of brass CW617N, which provides durability and resistance to corrosion in wet environments.

What is the recommended preparation before commissioning the system?
The manufacturer recommends using a system purging compound such as GEL.LONG LIFE 100 to ensure the system is free from debris before operation.
