DUAL-MIX - Combination heating kit - N-MAX 3 - 1 "xEK cabinet; 3-way; brass IVAR.CI 557 VP

Product detailed description

This combination heating kit is suitable for residential and commercial buildings where a hybrid heating system is required. It is commonly used in systems that integrate floor heating with radiators, allowing for balanced thermal distribution. The installation involves connecting the unit to the central heating system and configuring the control components to manage temperature and flow. The brass construction ensures durability and compatibility with standard heating media.

The kit includes a distributor with flow meters, a collector with shut-off valves, a circulation pump with electrical installation, a bypass, a thermostat with a separate immersion temperature sensor, and a control panel. It also includes mounting brackets, a pressure relief thermostat, two automatic air vents, a thermometer, and two rotating drain valves. The unit is designed for installation in a dedicated cabinet, with options for wall or floor mounting.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 6
Code	557671VPN
Brand	IVAR

The operating temperature of +90°C and PN 6 rating indicate that the unit is suitable for standard central heating systems with moderate pressure and temperature levels. These parameters are essential for determining compatibility with existing piping and for selecting appropriate insulation and expansion components.Installation and connection The unit connects via an internal 1 inch F thread, requiring precise alignment with the supply and return lines. The installation process includes securing the unit to the mounting brackets, connecting the electrical components, and configuring the control system. It is important to ensure that the flow meters and shut-off valves are correctly positioned to allow for system balancing and maintenance. A common mistake is neglecting to purge the system of air before commissioning, which can lead to inefficient operation and uneven heating.Compatibility and accessories The DUAL-MIX kit is compatible with standard floor and radiator heating systems. Additional components such as the IVAR.AC 614 E thermostat for circulation pump control may be required for full system functionality. The cabinet must be ordered separately, specifying the type (floor, wall, or without a cabinet) at the time of ordering. The unit is not supplied with a circulation pump control system, which must be integrated separately.Technical background for designers The unit operates by distributing heated water through a network of pipes connected to the distributor and collector. The brass construction provides good thermal conductivity and resistance to corrosion. The 3-way configuration allows for the simultaneous operation of floor and radiator heating circuits. The integration of a bypass ensures that the system can be balanced for optimal performance. The service life and efficiency of the unit depend on the quality of the installation, the cleanliness of the system, and the use of appropriate maintenance procedures.Service and operation Regular maintenance includes checking the air vents for blockages, inspecting the flow meters for accuracy, and verifying the operation of the pressure relief thermostat. 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 corrosion and scaling. No specific service intervals are provided in the brief.Frequently asked questions

Can the DUAL-MIX kit be used with a separate circulation pump control system?
Yes, the circulation pump control is not included in the kit and must be connected separately using an external thermostat such as the IVAR.AC 614 E.

Is the cabinet included in the standard kit?
No, the cabinet must be ordered separately by specifying the type (floor, wall, or without a cabinet) at the time of ordering.

Can the unit be installed in a system with a higher operating temperature than +90°C?
No, the operating temperature is limited to +90°C according to the technical specifications. Exceeding this may affect the performance and longevity of the components.

What should be done if the system contains impurities or air?
The system should be flushed thoroughly according to the manufacturer's instructions before commissioning. Automatic air vents are included, but manual purging may also be necessary to ensure proper operation.
