Modular manifold/collector assembly - 1 "xEK; 3-way; brass IVAR.CI 400 KC SET

Product detailed description

Modular manifolds and collectors are essential components in hydronic heating systems, particularly in multi-loop configurations such as underfloor heating, radiant panels or multi-zone radiators. This assembly is commonly used in residential, commercial and industrial buildings to manage flow distribution and collection efficiently. Installers and system designers rely on these units to ensure balanced flow rates and pressure drops across all circuits, avoiding thermal imbalances and system inefficiencies.

When installing in a central heating system, this modular unit provides a compact solution for integrating multiple circuits into a single manifold. The 3-way configuration allows for separate supply and return lines, with the third port typically connected to the main system header. This design supports both open and closed-loop systems, depending on the application requirements.

Technical parameters

The operating temperature limit of +90°C and nominal pressure rating of PN 10 define the conditions under which the manifold can safely operate. These parameters are crucial for selecting the correct component for the intended system, especially in domestic hot water or space heating applications. The 40 mm spacing between outlets ensures compatibility with standard pipe layouts and minimises the need for custom bracketing or fittings.

Installation and connection

This modular assembly requires careful alignment of the inlet and outlet connections during installation. The 1 inch inlet is designed for straight-line connection to the main supply, while the 3/4 inch threaded outlets connect to individual circuits. It is important to verify that the thread type matches the system piping to avoid leakage or misalignment. A common mistake is incorrect orientation of the manifold body, which can lead to uneven flow distribution and pressure loss.

Before final tightening, ensure that all connections are clean and free of debris. Apply a suitable sealing compound to threaded joints to prevent future leaks. Check the alignment of the mounting brackets to ensure the unit remains stable and does not shift during operation. Always follow the manufacturer’s guidelines for tightening torque when securing the manifold to the wall or support structure.

Compatibility and accessories

The modular design of this manifold allows it to be used with a range of flow control valves, shut-off valves and balancing devices. For complete system integration, additional components such as balancing valves and flow meters may need to be ordered separately. Accessories such as mounting brackets and sealing rings are usually included in the system setup, but it is recommended to verify the kit contents before installation.

Technical background for designers

The manifold operates as a central hub for distributing and collecting fluid within a hydronic system. The brass construction provides good corrosion resistance and mechanical strength, making it suitable for long-term use in wet environments. The CW617N grade offers enhanced durability and thermal conductivity, ensuring efficient heat transfer and minimal thermal lag. Integration into the system depends on the overall hydraulic balance, with flow rates and pressure drops calculated according to the system’s load and circuit lengths.

The longevity of the manifold is influenced by the quality of the installation, the cleanliness of the system fluid and the absence of particulate matter. Regular inspection of the connections and valves helps maintain performance over time. The modular nature of the unit also allows for easy expansion or reconfiguration of the system as needed.

Service and operation

Periodic inspection of the manifold should include checking for signs of leakage, corrosion or blockages in the flow paths. Ensure that all shut-off valves function correctly and that the flow control devices are adjusted according to the system requirements. While no specific service intervals are provided, it is recommended to perform a visual and functional check during routine system maintenance.

Frequently asked questions

Can this manifold be used in a system with variable flow rates?
Yes, the modular design supports variable flow rates through the use of compatible flow control valves. Adjustments should be made according to the system’s balancing requirements.

Is the manifold suitable for use with glycol-based fluids?
It is recommended to confirm compatibility with the manufacturer’s technical documentation, as the CW617N brass is generally suitable for water-based systems but may require additional checks for chemical compatibility.

How are the outlets aligned for connection?
The outlets are spaced 40 mm apart and feature 3/4 inch threaded connections. This spacing is standard for many pipe layouts and facilitates straightforward installation.

What should be checked after installation?
After installation, verify that all connections are tight, the manifold is level and that there are no visible leaks. Perform a pressure test to ensure the integrity of the system before commissioning.
