Manifold/collector assembly - without housing - 5/4 "xEK; 12-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 suitable for systems combining radiators and underfloor heating. The brass construction ensures durability in environments with fluctuating temperatures and pressures. Installers typically use this unit in central heating applications where multiple circuits need to be controlled independently.

The unit is ideal for use in multi-zone heating systems, allowing for individual circuit control and balancing. It is often found in buildings with complex heating layouts, such as large homes, office spaces, or industrial facilities. The assembly supports the integration of both radiator and underfloor heating circuits, making it a versatile solution for combined systems.

The operating temperature of +120°C and PN 10 pressure rating are essential for selecting the correct component for the system. These parameters ensure compatibility with standard heating circuits and allow for safe operation under typical load conditions. The CW617N brass material is suitable for use with water-based heating media and provides resistance to corrosion in closed systems.Installation and connection The manifold/collector assembly is connected using 5/4 inch external threads (EK). Installers should verify that the system piping is compatible with these thread sizes and that all connections are tightened to the manufacturer's torque specifications. It is important to align the distributor and collector correctly to avoid flow imbalances. Common installation errors include incorrect orientation of the unit and failure to clean the system before commissioning, which can lead to blockages or reduced efficiency. The unit should be mounted using the provided mounting brackets to ensure stability and ease of access for maintenance.Compatibility and accessories This manifold/collector is compatible with standard heating systems using water as the heat transfer medium. It is typically used with radiators and underfloor heating circuits. To complete the installation, additional components such as mounting brackets, insulation, and balancing valves may be required. The unit is designed for use with IVAR.CS 553 D systems and should be integrated according to the manufacturer's guidelines.Technical background for designers The unit operates by dividing the incoming flow into multiple circuits via the distributor and recombining the return flow through the collector. The CW617N brass material offers good thermal conductivity and mechanical strength, making it suitable for long-term use in heating systems. The design allows for individual circuit control, which is essential for system balancing and energy efficiency. The performance of the unit is influenced by the quality of the system water and the presence of impurities, which is why pre-commissioning flushing is recommended.Service and operation Regular inspection of the manifold/collector assembly is recommended to ensure all connections remain secure and that the valves function correctly. The unit should be flushed before commissioning, especially in systems combining different heating methods. No specific service intervals are provided, but any signs of leakage or blockage should be addressed promptly. The manufacturer recommends using GEL.LONG LIFE 100 to treat the system and prevent internal corrosion.Frequently asked questions
