DUAL-MIX - Combination heating kit - without cabinet - 1 "xEK; 8-way; brass IVAR.CI 557 VP

Product detailed description

This 8-way combination heating kit is suitable for installations in residential and commercial buildings where floor and radiator heating systems are used together. It allows for balanced distribution of heat and precise control of flow rates in each circuit. The brass construction ensures durability and resistance to corrosion, making it ideal for long-term operation in hydronic systems. The unit is designed for use in systems with a nominal pressure of PN 6 and a maximum operating temperature of +90 °C.

Installers working with mixed heating systems will find this kit useful for integrating different types of heat emitters into a single system. The kit includes a circulation pump, control valves, and a bypass, enabling efficient system operation and thermal balance. It is recommended to follow the manufacturer's guidelines for system flushing and preparation before commissioning to ensure optimal performance and longevity.

Technical parameters

Installation and connection

Installation involves connecting the distributor and collector to the main heating circuit using 1 inch internal female threads. The unit must be mounted securely using the provided mounting brackets to prevent vibration and misalignment. It is important to ensure that all connections are properly sealed and that the system is flushed before operation. Common installation mistakes include incorrect orientation of flow meters and failure to install the bypass correctly, which can affect system performance.

Compatibility and accessories

This kit is compatible with floor and radiator heating systems and can be integrated with external control systems such as the IVAR.AC 614 E for pump control. Additional components such as a circulation pump control thermostat may be required for full system functionality. The cabinet must be specified at the time of order using the appropriate code suffix (BS for no cabinet, N for wall-mounted, or no suffix for room-mounted).

Technical background for designers

The system operates by distributing heated water through individual circuits, with flow rates controlled by the integrated flow meters. The brass material provides good thermal conductivity and resistance to corrosion, making it suitable for use in mixed heating systems. The design allows for the integration of a bypass to maintain system pressure and flow balance. The efficiency and service life of the system depend on proper installation, system preparation, and the use of compatible components.

Service and operation

Regular maintenance includes checking for leaks, inspecting the operation of valves and the circulation pump, and ensuring that the system is free from air pockets. It is recommended to flush the system before commissioning and to use a system treatment such as GEL.LONG LIFE 100 to prevent corrosion and scaling. No specific service intervals are provided in the brief.
