Manifold/collector assembly - without housing - 5/4 "xEK; 11-way; brass IVAR.CS 553 DVP

Product detailed description

Manifold/collector assemblies are essential components in hydronic heating systems, particularly in floor heating applications. They allow for the balanced distribution and return of heated water across multiple circuits. This brass assembly is suitable for residential and commercial buildings where precise flow control and reliable shut-off are required. It is commonly used in systems combining floor heating with radiators, ensuring even heat distribution and efficient system operation.

Technical parameters

Installation and connection

Installation involves securing the manifold assembly to a mounting bracket and connecting it to the heating system's supply and return lines. The 5/4 inch EK thread type is used for both inlet and outlet connections. It is important to ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks. A common mistake is failing to clean the system before commissioning, which can lead to blockages and reduced efficiency. Always verify the alignment of the manifold with the system layout and ensure that the flow meters and shut-off valves are accessible for future maintenance.

Compatibility and accessories

This manifold is compatible with standard floor heating systems and can be integrated with circulation pumps and thermostatic controls. For complete system functionality, additional components such as mounting brackets and insulation may be required. It is recommended to use the GEL.LONG LIFE 100 preparation as part of the system commissioning process to enhance longevity and performance.

Technical background for designers

The manifold operates by dividing the incoming hot water into multiple circuits and collecting the return water for re-heating. The PN 10 pressure rating ensures that the manifold can handle typical operating pressures in hydronic systems. Proper sizing of the manifold is crucial to avoid flow imbalances and to ensure that each circuit receives the correct amount of heat.

Service and operation

Regular inspection of the manifold's connections and valves is recommended to ensure there are no leaks or blockages. The system should be flushed according to the manufacturer's instructions before commissioning, especially when combining floor heating with radiators. No specific service intervals are provided, but routine checks are advised to maintain system performance.

Frequently asked questions

Can this manifold be used with a circulation pump?
Yes, the manifold is compatible with circulation pumps and can be integrated into systems that require additional flow control.

What is the recommended preparation before commissioning?
It is recommended to use the GEL.LONG LIFE 100 preparation to treat the system and prevent functional issues caused by impurities.

Is the CW617N brass suitable for long-term use in heating systems?
CW617N brass offers high corrosion resistance and mechanical strength, making it suitable for long-term use in hydronic heating systems.

Can this manifold be used in systems with both floor heating and radiators?
Yes, the manifold is suitable for systems that combine floor heating with radiators, provided the system is properly flushed and maintained.
