UNIMIX - universal assembly, cabinet N-MAX 3 - 3/4 "xEK; 5-way; DAB.EVOSTA2 40-70/130; brass IVAR.UNIMIX

Product detailed description

The IVAR UNIMIX universal assembly is a complete solution for installers working on combined floor and radiator heating systems. It integrates a circulation pump, a three-way mixing valve, and a manifold system into a single unit, making it ideal for residential and commercial buildings where space is limited. This assembly is commonly used in underfloor heating applications where precise temperature control and flow balancing are required. The brass construction ensures durability and compatibility with standard heating media, while the modular design allows for flexible integration into existing or new systems.

Installers working with mixed heating systems benefit from the UNIMIX’s comprehensive package, which includes balancing valves, flow meters, and shut-off valves. The unit is designed for use with a DAB.EVOSTA2 40-70/130 pump, and the 3/4 inch internal thread connection ensures compatibility with standard pipe systems. The unit is typically installed in mechanical rooms or utility areas, where access for maintenance and inspection is required. It is important to ensure that the system is fully flushed and treated with a suitable inhibitor before commissioning to prevent blockages and corrosion.

The operating temperature of +90 °C and nominal pressure rating of PN 6 are essential for determining the suitability of the unit for specific heating systems. These parameters influence the selection of compatible components such as pipes, valves, and insulation materials. The CW617N brass material is resistant to corrosion and suitable for use with standard heating fluids, ensuring long-term reliability.Installation and connection The UNIMIX unit is connected using a 3/4 inch internal thread (F) connection. Installers should verify that the thread type and size match the system piping to avoid leaks or misalignment. The unit must be mounted on a stable surface using the provided mounting brackets to prevent vibration and stress on the connections. It is important to ensure that the pump is correctly aligned with the flow direction indicated on the unit. Common installation errors include incorrect orientation of the mixing valve and failure to secure the unit properly, which can lead to noise and reduced efficiency. After installation, the system should be tested for leaks and balanced using the built-in balancing valves.Compatibility and accessories The UNIMIX is compatible with standard floor heating systems and can be used in conjunction with radiators. It requires a DAB.EVOSTA2 40-70/130 pump for operation, which is not included in the standard package. The unit also works with IVAR.AC 614 E thermostats for pump control. Installers should ensure that the system includes a separate thermostat for pump operation if not already provided. Additional components such as expansion vessels and pressure relief valves may be required depending on the system design. The cabinet options (podium, wall-mounted, or without) must be specified at the time of order to ensure correct delivery.Technical background for designers The UNIMIX operates by combining a circulation pump with a three-way mixing valve to maintain a constant temperature in the heating system. The CW617N brass material is chosen for its strength and resistance to thermal expansion, making it suitable for long-term use in heating applications. The unit integrates into the system by connecting to the primary heating circuit and distributing heated water to the floor heating loops. The efficiency of the system depends on the correct sizing of the pump and the accurate balancing of the flow rates. The presence of a bypass allows for flow regulation in case of partial system shutdowns or maintenance.Service and operation Regular maintenance of the UNIMIX unit includes checking the pump for signs of wear, verifying the operation of the mixing valve, and inspecting the connections for leaks. The system should be flushed and treated with an inhibitor such as GEL.LONG LIFE 100 before commissioning to prevent internal corrosion and blockages. The pressure relief valve and expansion vessel should also be checked periodically to ensure safe operation. No specific service intervals are provided in the brief, but it is recommended to follow the manufacturer’s guidelines for maintenance procedures.Frequently asked questions

Can the UNIMIX be used with a different pump model?
While the unit is designed for use with the DAB.EVOSTA2 40-70/130 pump, other compatible models may be used provided they meet the system’s flow and pressure requirements. Always consult the manufacturer’s specifications before making changes.

Is the pump included in the standard package?
No, the pump is not included in the standard package. It must be ordered separately or controlled via an external thermostat such as the IVAR.AC 614 E.

Can the unit be mounted on a wall?
Yes, the unit can be mounted on a wall using the appropriate cabinet option (N for wall-mounted). This is specified at the time of order by adding the suffix N to the product code.

What is the purpose of the bypass in the UNIMIX?
The bypass allows for flow regulation in the system, ensuring that the pump continues to operate efficiently even when some circuits are closed or under maintenance. It helps prevent overheating and maintains system balance.
