Assembly distributor IVAR.CS 553 D, 12-way

Product detailed description

This 12-way distributor assembly is commonly used in multi-zone radiator heating systems in residential and commercial buildings. It allows for precise flow distribution and regulation across individual circuits. Installers typically integrate it into systems with a combination of radiators and underfloor heating, ensuring balanced thermal performance. The assembly is suitable for installations where zoning and individual circuit control are required for efficient heat distribution.

Proper installation of the assembly ensures that each circuit receives the correct flow rate and that the system operates efficiently. The unit is designed to be mounted in accessible locations, typically in mechanical rooms or utility areas. The connection size is 1 inch, and the assembly is compatible with standard heating system components. The PN 10 pressure rating ensures suitability for typical central heating applications.

Technical parameters

The maximum operating temperature of +120°C makes this assembly suitable for systems using glycol-based or water-based heat transfer media. The PN 10 nominal pressure rating indicates that the unit is appropriate for standard central heating systems. These parameters are essential for sizing the system and ensuring compatibility with other components such as pumps, valves, and heat emitters.

Installation and connection

Installation involves securing the distributor and collector to the wall using the included mounting brackets. The 1 inch connection requires a threaded connection to the main supply and return lines. Ensure that the system is fully drained and depressurised before connecting the assembly. Check that all valves are in the closed position and that the flow direction matches the manufacturer's specifications. A common mistake is incorrect orientation of the unit, which can lead to flow imbalances and inefficient operation.

Compatibility and accessories

This distributor is compatible with standard heating system components such as circulators, expansion vessels, and thermostatic valves. For accurate system monitoring, it is recommended to install a temperature sensor and flow meter. The assembly does not include these accessories and must be ordered separately. Ensure that all components are from the same manufacturer or are compatible with the IVAR system to avoid integration issues.

Technical background for designers

The IVAR.CS 553 D operates by distributing the incoming flow to individual circuits via the distributor and collecting the return flow through the collector. The use of brass (CW617N) ensures good corrosion resistance and long-term durability in heating systems. The design allows for individual circuit balancing, which is essential for maintaining even heat distribution. The efficiency of the system is influenced by the correct sizing of the distributor, the accuracy of the flow settings, and the overall system design.

Service and operation

Regular maintenance includes checking for leaks, ensuring all valves are functioning correctly, and verifying the system's pressure and temperature. The manufacturer recommends a full system flush before commissioning, especially in systems combining underfloor and radiator heating. No specific service intervals are provided, but routine checks are advised to ensure long-term performance. Any blockages or contamination in the system can affect the distributor's operation and must be addressed promptly.

Frequently asked questions

Can the IVAR.CS 553 D be used with underfloor heating systems?
Yes, the assembly is suitable for use with underfloor heating systems. However, it is recommended to install temperature and flow sensors for accurate system control.

Is the assembly suitable for high-pressure systems?
No, the unit is rated for a nominal pressure of PN 10 and is not suitable for high-pressure applications beyond this rating.

Can the distributor be installed in a vertical position?
No, the assembly must be installed horizontally to ensure correct flow distribution and prevent imbalances in the system.

What materials are used in the construction of the distributor?
The distributor is constructed from brass (CW617N), which provides good corrosion resistance and durability in heating applications.
