IVAR.CI 553 VP - manifold with regulating flow meters

The IVAR.CI 553 VP category includes brass manifolds with integrated flowmeters for use in underfloor heating systems. These manifolds are designed for precise flow regulation of incoming water, ensuring even heat distribution across the floor surface. The units are constructed from CW617N brass, a material known for its durability and resistance to corrosion. They are suitable for installation in heating systems operating at a maximum temperature of +90 °C and a pressure rating of PN 10.

Each manifold is equipped with side inputs of 1" F or 5/4" F and 3/4" EK threaded outputs. The output spacing is fixed at 50 mm, and the number of circuits can be selected from 2-way up to 12-way configurations. The flowmeters allow for a regulation range of 0 to 5 l/min, enabling fine-tuning of the system to match the thermal requirements of the space.

How to choose

• Select the number of circuits (2 to 12) based on the size and layout of the underfloor heating system.
• Choose the input size (1" F or 5/4" F) to match the existing piping and system design.
• Ensure compatibility with 3/4" EK threaded connections for the output side of the manifold.
• Verify that the system operates within the pressure and temperature limits of PN 10 and +90 °C.

Frequently asked questions

What is the maximum number of circuits available in this range?
The IVAR.CI 553 VP is available in configurations with up to 12 circuits.

Can these manifolds be used with both floor and radiator heating systems?
Yes, but it is recommended to flush the entire system before commissioning to remove any impurities that may affect performance.
