Manifold/collector assembly - cabinet P-KLASIK 2 - 1 "xEK; 3-way; brass IVAR.CS 553 DRS

Product detailed description

This manifold/collector assembly is commonly used in residential and commercial buildings equipped with radiator-based central heating systems. It serves as a central distribution point for hot water to multiple circuits and collects return flows efficiently. Installers typically work with systems that require precise flow control, balancing, and isolation of individual circuits for maintenance or seasonal adjustments. The unit is particularly suited for applications where integration with existing piping infrastructure is required and where long-term reliability is essential.

The brass construction ensures high resistance to corrosion and mechanical stress, making it suitable for both new installations and system upgrades. It supports the connection of multiple radiators via separate branches and is often used in combination with thermostatic controls and circulation pumps. The inclusion of air vents and drain valves simplifies commissioning and seasonal maintenance procedures.

Technical parameters

Installation and connection

Installation begins with verifying the correct orientation of the distributor and collector within the cabinet. The assembly is typically mounted on a wall using the provided mounting brackets, ensuring secure alignment and accessibility. Connections are made via 1-inch EK threads, requiring compatible pipe fittings and sealing materials. It is essential to ensure that all threaded connections are tightened to the recommended torque to prevent leaks.

Before final tightening, check for proper alignment of the branch connections and ensure that all valves are in the closed position during initial assembly. A common mistake is incorrect orientation of the air vent and drain valves, which can lead to poor system performance. After installation, perform a pressure test to confirm system integrity and inspect for any signs of leakage around the joints.

Compatibility and accessories

This manifold/collector assembly is compatible with standard radiator circuits and central heating systems using copper or steel piping. For optimal performance, ensure that the system includes appropriate balancing valves and circulation pumps. Accessories such as pressure gauges, expansion vessels and flow meters may also be required depending on the system design. Additional components should be selected according to the manufacturer’s technical guidelines.

Technical background for designers

The operating principle of the manifold/collector assembly is based on the controlled distribution and collection of heated water across multiple circuits. The CW617N brass material offers good thermal conductivity and resistance to corrosion, making it suitable for long-term operation in heating systems. The design allows for individual circuit isolation, which facilitates system maintenance and energy efficiency improvements. The selection of the correct cabinet type (wall-mounted or without) depends on the available space and installation requirements.

System efficiency is influenced by the correct sizing of the manifold relative to the total heat load and the number of connected circuits. Poorly balanced systems can lead to uneven heat distribution and increased energy consumption. Designers should also consider the thermal expansion characteristics of the materials used in the piping network to avoid mechanical stress on the manifold assembly.

Service and operation

Periodic inspection of the manifold assembly is recommended to ensure all valves function correctly and there is no blockage in the air vent or drain lines. During seasonal shutdown, it is advisable to drain the system and check for internal corrosion or sediment buildup. The manufacturer recommends a complete system flush and treatment with GEL.LONG LIFE 100 to maintain internal cleanliness and prolong component life.

Before commissioning the system after any maintenance or installation, verify the tightness of all connections and the correct positioning of valves. Any unusual noise or pressure drop during operation should be investigated promptly to identify potential issues such as clogging or valve failure.

Frequently asked questions

Can the manifold/collector assembly be used with floor heating systems?
No, this model is specifically designed for radiator circuits and is not suitable for floor heating applications due to the different flow and temperature requirements.

Is it possible to order the assembly without the cabinet?
Yes, the cabinet can be omitted by specifying the code + BS. Alternatively, wall-mounted or room-mounted options are available by adding + N or the base code respectively.

What sealing material is recommended for the threaded connections?
Thread sealant or PTFE tape suitable for PN 10 systems should be used to ensure leak-free connections and compliance with pressure ratings.

Are the shut-off valves included interchangeable with other brands?
Not recommended. The valves are factory-fitted and calibrated for this specific assembly. Replacing them with non-matching components may affect system balance and performance.
