Manifold/collector assembly - for underfloor heating - without cabinet - 1 "xEK; 10-way; brass IVAR.CS 553 VP

Product detailed description

This manifold assembly is specifically designed for underfloor heating applications in residential and commercial buildings. It enables precise flow distribution and return collection across multiple zones. Installers working with radiant floor systems benefit from its modular design and compatibility with standard heating circuits.

The unit is suitable for integration into central heating systems with mixed configurations, such as those combining underfloor heating with radiators. The brass construction ensures durability and resistance to corrosion in typical heating environments. The 10-circuit configuration allows for zoning in larger spaces or multi-room installations.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 10
Code	553978BS
Brand	IVAR

The operating temperature of +90°C is suitable for standard hydronic heating systems using water as the heat transfer medium. The PN10 pressure rating indicates suitability for low-pressure domestic heating systems. The CW617N brass alloy offers high mechanical strength and resistance to thermal stress.

Installation and connection

The manifold is connected via 1 inch EK thread ports, which require compatible pipe fittings and insulation to prevent heat loss. During installation, ensure the supply and return lines are correctly aligned with the manifold’s inlet and outlet. The assembly includes mounting brackets for secure wall or floor mounting. Before commissioning, verify that all valves are fully open and that the system is free of debris. Common errors include incorrect orientation of the flow control meters or misalignment of the shut-off valves. Always follow the manufacturer’s instructions for purging the system to avoid blockages caused by particulates.

Compatibility and accessories

This manifold is designed for use with standard underfloor heating pipes and manifolds with similar connection standards. It does not include a pump or enclosure; these must be ordered separately. Accessories such as insulation covers or balancing tools may be required depending on the system design.

Technical background for designers

The manifold functions by dividing the primary flow into individual circuits and collecting the return flow for re-heating. The CW617N brass provides good thermal conductivity and long-term stability under continuous operation. Designers should consider the need for expansion joints in larger systems to accommodate thermal movement. The integration of flow control meters allows for balancing between circuits, ensuring even heat distribution. System efficiency depends on proper sizing of the manifold relative to the total circuit length and heat demand of the space.

Service and operation

Regular inspection of the valves and meters is recommended to ensure smooth operation. Check for signs of leakage or wear, especially after system flushes. No scheduled service intervals are specified, but the system should be flushed periodically according to the manufacturer’s guidelines to maintain performance.

Frequently asked questions

Can this manifold be used with a boiler operating at higher pressures?
It is rated for PN10, so it should not be used with systems exceeding this pressure. Check the boiler’s specifications before installation.

Are the flow control meters adjustable during operation?
Yes, the meters allow for manual adjustment of flow rates per circuit to balance the system during commissioning.

Does the brass construction require special treatment in aggressive water conditions?
Brass is generally resistant to corrosion, but in highly aggressive environments, additional protection measures may be needed based on local water quality.

Is the manifold compatible with digital room thermostats?
It works with any system that controls the boiler or pump, but it does not have built-in electronic controls.
