Manifold/collector assembly - without housing - 5/4 "xEK; 2-way; brass IVAR.CS 553 D
Code: 400282Related products
Product detailed description
Manifold/collector assemblies are essential components in hydronic heating systems, particularly in commercial and residential buildings with radiator-based heating. These units allow for the controlled distribution and return of heated water to and from individual circuits. Installers working on multi-circuit systems benefit from the modularity and precision these assemblies provide. The brass construction ensures durability in systems with moderate operating temperatures and pressures.
When integrating these assemblies into a heating system, careful attention must be given to the hydraulic balance and the compatibility of connected components. The assembly is suitable for systems where a two-way flow is required, ensuring even heat distribution across connected radiators. The absence of an enclosure allows for custom integration into mechanical rooms or behind panels, depending on the installation requirements.

Compatibility and accessories
This manifold/collector is compatible with standard radiator circuits and requires matching EK fittings for connection. Additional components such as mounting brackets and insulation materials may be needed depending on the installation environment. No related products are specified for this model.Technical background for designers
The assembly operates by distributing heated water through the distributor and collecting the return flow via the collector. The use of brass (CW617N) ensures resistance to corrosion and mechanical wear in typical heating applications. The material's thermal conductivity supports efficient heat transfer, while the two-way design simplifies system layout. Long-term performance depends on proper system flushing and the use of protective treatments such as GEL.LONG LIFE 100 to prevent internal fouling.Service and operation
Regular inspection of the valves and connections is recommended to ensure continued system efficiency. The manufacturer emphasizes the importance of system flushing before commissioning, particularly in mixed systems with underfloor and radiator heating. No specific service intervals are provided, but adherence to the manufacturer's maintenance guidelines is advised to prevent operational issues caused by debris or corrosion.Frequently asked questions
Can this manifold be used in mixed heating systems?
Yes, it is suitable for systems combining radiator and underfloor heating, provided the system is properly flushed and maintained according to the manufacturer's instructions.
What type of valves are included in the assembly?
The distributor includes control valves for flow regulation, while the collector features shut-off valves for isolation purposes.
Is a housing required for installation?
No, the assembly is supplied without housing, allowing for flexible integration into the system layout.
What is the recommended preparation before system activation?
Thorough system flushing is required before commissioning, especially when using mixed heating systems. The use of GEL.LONG LIFE 100 is recommended to protect against internal fouling.
