Manifold/collector assembly - without housing - 5/4 "xEK; 12-way; brass IVAR.CS 553 DVP

Product detailed description

Manifold assemblies are essential components in hydronic heating systems, particularly in underfloor heating applications. They serve as central distribution points for hot water to individual heating loops, ensuring balanced flow and efficient heat distribution. This model is commonly used in residential and commercial buildings where precise flow control and zoning are required. Installers working with mixed systems combining underfloor heating with radiators will find this unit suitable for integration into the primary circuit, provided system flushing and chemical treatment are carried out as per manufacturer guidelines.

The 12-way configuration allows for the management of multiple heating zones, making it ideal for medium to large floor heating installations. The brass construction ensures durability and resistance to corrosion, while the inclusion of flow meters and shut-off valves supports accurate system balancing and maintenance. The unit is supplied with mounting brackets for secure installation within the heating room or technical space.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 10
Code	400292DVP
Brand	IVAR

The operating temperature of +90°C and nominal pressure of PN 10 define the conditions under which this manifold can be safely used. These parameters are critical for sizing the unit to match the system's hydraulic and thermal requirements. The brass material is suitable for use in closed heating systems with glycol or water as the heat transfer medium. The CW617N grade is selected for its mechanical strength and resistance to thermal stress.

Installation and connection

The manifold assembly features 5/4"xEK connections, which are typically used for connecting to the primary circuit or circulation pumps. Installers must ensure that all connections are tightened to the correct torque and that the system is fully flushed before commissioning. A common mistake is neglecting to clean the system thoroughly, which can lead to blockages in the flow meters or valves. The mounting brackets should be fixed to a stable surface, and the unit must be installed in a location that allows for easy access to the valves and meters for future maintenance.

Compatibility and accessories

This manifold is compatible with IVAR floor heating systems and can be integrated with circulation pumps, expansion vessels, and control units. Additional components such as insulation covers or pressure gauges may be required depending on the system design. No related products are specified for this model, so installers should verify the full system requirements before installation.

Technical background for designers

The manifold operates by dividing the incoming hot water into multiple circuits and collecting the return flow for re-heating. The brass CW617N material is chosen for its thermal conductivity and resistance to scaling, which is important in systems with high water hardness. The integration of flow meters allows for precise balancing of the system, ensuring even heat distribution. The service life and efficiency of the unit depend on the quality of the system water and the regularity of maintenance. The use of chemical treatments such as GEL.LONG LIFE 100 is recommended to prevent corrosion and fouling.

Service and operation

Regular visual inspections are recommended to check for leaks, corrosion, or blockages in the flow meters and valves. The system should be flushed periodically according to the manufacturer's instructions to remove sediment and debris. No specific service intervals are provided in the brief, but adherence to the recommended chemical treatment and flushing procedures is essential for long-term performance.

Frequently asked questions

Can this manifold be used in a mixed system with radiators and underfloor heating?
Yes, provided the system is thoroughly flushed and treated with a corrosion inhibitor such as GEL.LONG LIFE 100 before commissioning.

What is the maximum operating temperature for this unit?
The maximum operating temperature is +90°C as specified in the technical parameters.

Is a housing required for this manifold?
No, this model is supplied without a housing and must be mounted in a suitable location with access for maintenance.

Can the flow meters be replaced individually?
Yes, the flow meters are designed for individual replacement, but installation should be carried out by a qualified technician to ensure correct calibration.
