Assembly distributor IVAR.CS 553 VP, 10-way

Product detailed description

The IVAR.CS 553 VP 10-way distributor is commonly used in residential and commercial buildings where hydronic floor heating systems are installed. It is typically integrated into systems that require precise flow control and zoning. Installers working on mixed systems combining floor heating with radiators will find this distributor suitable for balancing and managing thermal output. The unit is designed for use with low-temperature hot water systems and is compatible with standard heating circuits.

As part of a balanced hydronic system, this distributor ensures even heat distribution across multiple zones. It is often used in underfloor heating applications where individual room control is required. The inclusion of flow meters and shut-off valves allows for accurate regulation and isolation of each circuit, which is essential for system maintenance and efficiency.

Code	553978
Brand	IVAR

The nominal pressure rating of PN 10 indicates that the distributor is suitable for systems operating at up to 10 bar. The maximum operating temperature of +90°C is typical for standard hydronic heating systems. These parameters are essential for selecting the correct distributor size and ensuring compatibility with the system's pressure and temperature conditions.Installation and connection The distributor is connected using 1 inch nominal pipe size with external thread (EK). Installers should ensure that all connections are properly tightened and sealed to prevent leaks. The distributor includes mounting brackets for secure installation on walls or within mechanical rooms. Prior to installation, verify that the system is clean and free of debris to avoid blockages in the flow meters or valves. A common mistake during installation is incorrect alignment of the distributor and collector, which can lead to uneven flow distribution and reduced system efficiency.Compatibility and accessories This distributor is compatible with standard floor heating manifolds and is designed for use with copper or PEX piping. Additional components such as circulation pumps, expansion vessels, and balancing valves may be required depending on the system design. The package includes two ball valves with handles, two intermediate manifolds with automatic air vents and drain valves, and two caps for unused ports. No specific related products are listed for this model.Technical background for designers The distributor operates by dividing the incoming hot water into multiple circuits and allowing individual flow control through integrated flow meters. The use of brass (CW617N) ensures durability and resistance to corrosion in hot water environments. The design allows for easy integration into existing heating systems and supports zoning strategies for improved thermal comfort. The longevity and efficiency of the system depend on the quality of the installation, the cleanliness of the water, and the correct sizing of the distributor relative to the system load.Service and operation Regular maintenance includes checking for leaks, verifying the operation of flow meters and shut-off valves, and ensuring that the system remains free of debris. The manufacturer recommends a system flush before commissioning, especially in mixed systems with radiators and floor heating. If not maintained properly, particulate matter in the system can cause blockages and reduce the distributor's effectiveness. No specific service intervals are provided in the brief.Frequently asked questions
