DUAL-MIX - Combination heating kit - without cabinet - 1 "xEK; 4-way; brass IVAR.CI 557 VP

Product detailed description

This combination heating kit is suitable for installations requiring both floor and radiator heating. It is commonly used in residential and commercial buildings where a balanced thermal distribution is essential. The system integrates a manifold with flow meters, a collector with shut-off valves, and a circulation pump. The brass construction ensures durability and compatibility with standard heating media. The kit is designed for use in systems operating at up to 90°C and PN 6, making it suitable for conventional heating applications. Installers must ensure proper system flushing and preparation before commissioning to avoid blockages and inefficiencies.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 6
Code	557672VPBS
Brand	IVAR

The operating temperature of +90°C and nominal pressure of PN 6 define the conditions under which the system can safely function. These values are critical for determining the compatibility with other components in the heating system. The material, CW617N brass, is selected for its resistance to corrosion and mechanical stress, ensuring long-term reliability in typical heating environments.

Installation and connection

The DUAL-MIX kit is connected via an internal 1-inch thread (1” F), which must be aligned with the corresponding pipe connections in the system. Installers should verify the correct orientation of the manifold and collector to ensure proper flow direction. The unit should be mounted using the provided mounting brackets to maintain stability. A common mistake is incorrect alignment of the flow meters or valves, which can lead to inaccurate readings or flow imbalances. It is essential to check all connections for tightness and to ensure that the bypass is correctly configured to allow for system balancing.

Compatibility and accessories

The DUAL-MIX kit is compatible with standard floor heating systems and radiator circuits. Additional components such as a control thermostat for the circulation pump (IVAR.AC 614 E) may be required for full system automation. The circulation pump is not included in the kit and must be sourced separately. The unit also requires a separate power supply and electrical installation for the pump. The cabinet is not included in this version (BS variant), so a suitable enclosure must be selected and ordered separately based on the installation requirements.

Technical background for designers

The DUAL-MIX kit operates by distributing heated water through multiple circuits using a manifold and collector system. The brass material provides good thermal conductivity and mechanical strength, making it suitable for long-term use in heating systems. The integration of flow meters and shut-off valves allows for precise control and monitoring of flow rates. The system's efficiency is influenced by the correct sizing of the manifold and the use of compatible insulation and piping. The bypass ensures that the system can be balanced without the need for additional components.

Service and operation

Regular maintenance includes checking for leaks, ensuring the correct operation of the circulation pump, and verifying the functionality of the flow meters and shut-off valves. The system should be flushed according to the manufacturer's instructions before commissioning, especially when combining floor and radiator heating. The use of a system treatment such as GEL.LONG LIFE 100 is recommended to prevent internal corrosion and scaling. No specific service intervals are provided, but periodic inspections are advised to maintain system performance.

Frequently asked questions

Can the DUAL-MIX kit be used with a separate circulation pump?
Yes, the circulation pump is not included in the kit and must be connected separately. The IVAR.AC 614 E thermostat can be used for pump control.

Is the cabinet included in the kit?
No, the cabinet is not included in the BS variant. A separate cabinet must be ordered based on the installation requirements.

What is the maximum operating temperature of the DUAL-MIX kit?
The maximum operating temperature is +90°C, as specified in the technical parameters.

Can the DUAL-MIX kit be used in a system with both floor and radiator heating?
Yes, the kit is specifically designed for combined floor and radiator heating systems. However, the system must be flushed and prepared according to the manufacturer's instructions before commissioning.
