IVAR.CS 553 DVP without pump

The IVAR.CS 553 DVP category includes manifold/collector assemblies for floor heating systems. These units consist of a distributor with individual flow meters and a collector with shut-off valves, all mounted on support brackets. They are designed for use in hydronic heating systems operating at a maximum temperature of 90 °C and pressure rating PN 10. The manifolds are manufactured from CW617N brass, a durable and corrosion-resistant material suitable for long-term operation in heating applications.

These manifolds are commonly used in underfloor heating systems and can be integrated into systems with radiators. They are available in configurations with 10, 11, or 12 circuits, making them suitable for medium to large floor heating layouts. The units are supplied without housing, allowing for custom installation into technical rooms or wall-mounted enclosures.

How to choose

• Select the number of circuits (10, 11, or 12) based on the number of heating loops in your system.
• Confirm the connection type is 5/4" x EK for compatibility with standard pipe fittings.
• Ensure the material (CW617N brass) is suitable for your system’s chemical and thermal conditions.
• Verify compatibility with your system’s pressure and temperature limits (PN 10, T = +90 °C).

Frequently asked questions

Can these manifolds be used in mixed heating systems with radiators?
Yes, they are suitable for mixed systems, but it is essential to perform a full system flush before commissioning to remove debris.

What is the recommended maintenance procedure?
Before commissioning and after major system changes, a full system flush is required. It is also advised to treat the system with GEL.LONG LIFE 100 to prevent internal corrosion.
