Modular manifold/collector assembly - 1 "xEK; 8-way; brass IVAR.CI 400 KC SET

Product detailed description

This modular manifold/collector assembly is commonly used in hydronic heating systems for residential and commercial buildings. It allows for the distribution and collection of heated water in underfloor heating, radiant panels, and other low-temperature heating applications. The assembly is typically installed in mechanical rooms or technical areas where space is limited and modular components are required for flexibility and scalability. The brass construction ensures durability and resistance to corrosion, making it suitable for long-term operation in closed-loop systems.

Installers working with this manifold/collector assembly typically deal with system balancing, zoning, and flow regulation. The modular design allows for easy expansion or reconfiguration of the system without the need for complete replacement. The 8-way configuration is ideal for systems with multiple heating circuits, such as multi-room underfloor heating or multiple radiant panels. The assembly is often integrated with thermostatic valves, circulator pumps, and expansion vessels to ensure efficient system performance.

Technical parameters

The operating temperature of +90°C and nominal pressure of PN 10 are critical for system sizing and selection. These parameters ensure the manifold/collector can handle typical domestic hot water and heating system conditions. The 40 mm spacing between outlets allows for standard pipe routing and fitting with conventional pipe diameters. The 3/4 inch EK connection size ensures compatibility with standard piping systems in Europe.

Installation and connection

Installation begins with ensuring the manifold/collector is delivered in a disassembled state, as per the manufacturer's instructions. The side inlets are 1 inch in diameter, and the outlets are spaced 40 mm apart with 3/4 inch EK connections. Installers should verify that all components are present, including the modular distributor with flow meters, collector with shut-off valves, two end caps with manual air vents and drain valves, mounting brackets, and two ball valves with threaded connections.

Common installation mistakes include incorrect orientation of the flow meters and misalignment of the mounting brackets. It is essential to ensure that the flow meters are installed in the correct direction to allow accurate flow measurement. The manifold should be mounted horizontally using the provided brackets to prevent stress on the connections. All threaded connections should be sealed with appropriate thread sealant or PTFE tape to prevent leaks.

Compatibility and accessories

This modular manifold/collector is compatible with standard 3/4 inch EK piping systems and can be integrated with thermostatic valves, circulator pumps, and expansion vessels. To complete the system, additional components such as pipe insulation, flow control valves, and temperature sensors may be required. The assembly is designed to work with closed-loop hydronic systems and is suitable for use with water as the heat transfer medium.

Technical background for designers

The modular manifold/collector operates by distributing and collecting heated water from multiple circuits. The flow meters in the distributor allow for precise flow control, which is essential for system balancing. The shut-off valves in the collector enable individual circuit isolation for maintenance or repairs. The integration of manual air vents and drain valves ensures easy system commissioning and maintenance.

The service life and efficiency of the manifold/collector depend on proper system design, including correct sizing of the flow meters and shut-off valves. Overloading the system beyond the specified pressure and temperature limits can lead to premature wear or failure. The modular design allows for easy replacement of individual components without the need to replace the entire assembly.

Service and operation

Regular maintenance includes checking for leaks at all connections and verifying the operation of the flow meters and shut-off valves. The manual air vents and drain valves should be inspected to ensure they are free from blockages and operate smoothly. No specific service intervals are provided in the brief, but it is recommended to inspect the manifold/collector during routine system maintenance.
