Manifold - fitted with regulating screws - 1 "xEK; 10-way; brass IVAR.CI 553

Product detailed description

Manifolds are essential components in hydronic heating systems, particularly in floor heating applications where precise flow distribution is required. This 10-way model is commonly used in residential and commercial buildings to manage multiple heating loops. Installers working with combined floor and radiator heating systems must ensure thorough system flushing and preparation to prevent blockages and ensure long-term efficiency.

When integrating this manifold into a system, it is important to consider the hydraulic balance and the need for individual loop control. The brass construction ensures durability and resistance to corrosion, making it suitable for use in closed heating circuits. The 1 inch inlet and 3/4 inch EK outlets allow for flexible connection to various pipe systems and components.

The operating temperature of +120 °C and nominal pressure of PN 10 define the conditions under which the manifold can be safely used. The 50 mm spacing between outlets is important for planning the layout and ensuring compatibility with other system components such as valves and insulation. These parameters are critical for correct system sizing and selection of compatible components.

Installation and connection

The manifold is installed with a side-mounted 1 inch female inlet and 10 outlets with 3/4 inch EK threads. The 50 mm spacing between outlets must be considered when routing pipes and insulation. Installers should verify that all connections are clean and free of debris before tightening. A common mistake is failing to flush the system prior to commissioning, which can lead to blockages in the manifold or downstream components. It is also important to ensure that the manifold is mounted in a stable and accessible location for future maintenance.

Compatibility and accessories

This manifold is compatible with floor heating systems that use 3/4 inch EK connections. To complete the system, additional components such as insulation plates, balancing valves and temperature sensors may be required. It is recommended to use the manufacturer's recommended system preparation products to ensure long-term performance.

Technical background for designers

The manifold operates by dividing the incoming flow into multiple controlled outlets. The brass CW617N material provides good thermal conductivity and resistance to corrosion. The regulating and shut-off screws allow for individual flow adjustment and isolation of specific loops. The integration into the system depends on the hydraulic design and the need for balancing. The service life and efficiency are influenced by the quality of the installation, system flushing and the use of compatible media.

Service and operation

Regular inspection of the manifold for leaks and proper operation of the regulating screws is recommended. The system should be flushed periodically to remove debris and maintain flow efficiency. The manufacturer highlights the importance of system preparation and maintenance to prevent functional issues caused by impurities in the system.
