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

Product detailed description

This manifold/collector assembly is commonly used in residential and commercial heating systems where precise flow distribution and collection are required. It is typically installed in systems with multiple radiators or in configurations that combine radiator and underfloor heating. The brass construction ensures durability and compatibility with standard heating media, while the 4-way design allows for efficient flow management in medium-sized installations. Installers should ensure proper alignment and secure mounting to prevent vibration and leakage.

The assembly is suitable for use in central heating systems where zoning and flow regulation are necessary. It is often found in applications where individual room temperature control is required, such as in multi-room buildings or in systems with mixed heating methods. The inclusion of control and shut-off valves allows for easy maintenance and system isolation during repairs or seasonal shutdowns.

Technical parameters

Material	Brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Code	400284
Brand	IVAR

The operating temperature of +120°C and PN 10 pressure rating are critical for selecting the correct manifold for a given system. These parameters ensure compatibility with standard heating circuits and allow for safe operation under typical load conditions. The CW617N brass material is selected for its resistance to corrosion and mechanical stress, making it suitable for long-term use in closed heating systems.

Installation and connection

The manifold/collector assembly is connected using 5/4 inch EK threads, which are commonly found in European heating systems. Installers should verify that all connections are clean and free from debris before tightening. The assembly should be mounted using the provided fixing brackets to ensure stability and prevent movement during operation. Common installation errors include incorrect orientation of the distributor and collector, which can lead to flow imbalances and reduced system efficiency. It is important to follow the manufacturer's instructions for mounting and alignment to avoid these issues.

Compatibility and accessories

This manifold is designed to be used with standard heating system components such as radiators, underfloor heating manifolds, and circulation pumps. It is compatible with systems operating under the specified pressure and temperature conditions. To complete the installation, additional components such as insulation, mounting brackets, and control systems may be required. No specific related products are listed for this model.

Technical background for designers

The manifold functions by distributing heated water evenly to multiple circuits and collecting the return flow for re-heating. The brass material provides good thermal conductivity and structural stability, ensuring even heat distribution and minimal pressure drop. The CW617N alloy is known for its resistance to dezincification and stress corrosion, making it suitable for use in closed heating systems. The design allows for integration into both new and retrofit systems, with the 4-way configuration being ideal for smaller to medium-sized installations. The performance of the manifold is influenced by the quality of the connections and the overall system balance.

Service and operation

Regular inspection of the manifold is recommended to ensure that all connections remain secure and that there is no leakage. The manufacturer recommends a thorough system flush before commissioning, especially in systems that combine different heating methods. This helps to remove any particulate matter that could affect the operation of the valves or cause blockages. No specific service intervals are provided, but maintenance should be carried out in accordance with standard heating system practices.

Frequently asked questions

Can this manifold be used in systems with both radiators and underfloor heating?
Yes, the manifold is suitable for mixed heating systems. However, the manufacturer recommends a system flush before commissioning to remove any debris that could affect performance.

Is it necessary to use a specific preparation before commissioning?
The manufacturer recommends using the GEL.LONG LIFE 100 preparation to treat the heating system before operation. This helps to ensure long-term performance and reduce the risk of internal corrosion.

What is the maximum operating temperature for this manifold?
The maximum operating temperature is +120°C, as specified in the technical parameters. Exceeding this temperature may affect the integrity of the connections and the performance of the valves.

Can this manifold be used with other brands of heating components?
Yes, the manifold is compatible with standard heating system components as long as the pressure and temperature conditions are within the specified limits. The 5/4 inch EK connections are widely used in European heating systems.
