Boiler assembly - MIX 3 - mixed, with bypass valve

The boiler assembly - MIX 3 - mixed with discharge valve category includes pre-assembled boiler modules designed for integration into heating and hot water systems. Each set includes a horizontal distribution manifold, supply and return piping, a circulation pump, a 3-way mixing valve, a discharge valve, and thermal insulation. These assemblies are suitable for use in residential and commercial heating systems where precise temperature control and hydraulic balancing are required.

Typical applications include central heating systems, apartment buildings, and industrial installations where a compact and pre-configured boiler solution is needed. The assemblies are designed for operation at a maximum temperature of +120°C and a flow rate of up to 3000 l/h.

How to choose

• Confirm the nominal diameter (DN 32) matches the system piping and manifold connections.
• Select the appropriate pump model (e.g., DAB.EVOSTA 2 or 3 series) based on flow and pressure requirements.
• Choose between 230V or 24V variants depending on the electrical system and control compatibility.
• Ensure the brass materials (CW617N, CB753S) are compatible with the system’s chemical and thermal conditions.
• Verify the internal/external thread type (5/4" F × 5/4" M) aligns with the boiler or heat exchanger inlet/outlet.

Frequently asked questions

Can the MIX 3 assembly be used with a modulating boiler?
Yes, the 3-way mixing valve and servo drive (IVAR.ACTUATORS 05 or 24S) allow for proportional temperature control, making it compatible with modulating boilers.

What is the maximum allowable working pressure?
The assembly is rated for PN 10, suitable for standard domestic and low-pressure industrial heating systems.
