Boiler module IVAR.TV3-300 DN 40 with 3-way mixing valve, without circulation pump

Product detailed description

The IVAR.TV3-300 DN 40 boiler module (code IVA49043610) prepares and distributes heating water, mixing it through a 3-way valve. It is designed for radiator, underfloor and wall heating in systems whose heat source supplies a strongly fluctuating flow temperature – typically with a solid-fuel boiler. It operates in closed hot-water heating and cooling systems.

Module equipment

• 3-way mixing valve, Kv 25
• space for a single or twin circulation pump (pump not included)
• flow and return pipes with DN 40 flanges for connection to the horizontal distribution manifold
• four wafer-type butterfly valves, check valve and pressure ports
• two fill/drain valves on the primary side
• two 0–120 °C thermometers and sensor pockets Ø 6 mm
• Trocellen C080 thermal insulation, 30 mm thick (λ 0.034 W/m·K)

Output and dimensions

The module handles up to 150 kW at ΔT 20 K and up to 38 kW at ΔT 5 K, at a flow rate of up to 6460 l/h. Maximum operating pressure is 10 bar, temperature +100 °C. The Fe EN 10217-1 steel body is epoxy powder coated, the connection centre distance is 300 mm and the dimensions are 940 × 660 × 477 mm.

Actuator and installation

The actuator is ordered separately: IVAR.SERVOPOHON TV3 230 V with 3-point control (IVA20317350) or 24 V with 0–10 V control (IVA20317351). The module mounts directly on the IVAR.HC-DN 40 manifold or via IVAR.CONNECTA reduction sets, fixings are included. The valve is on the right from the factory; turning the valve and return pipe as described in the manual gives the left-hand version. Do not use mineral-oil lubricants on the EPDM seals. Installation of the module and fitting and wiring of the pump should be left to a qualified installer. Flush the system before start-up.

Technical data

Frequently asked questions

When should I choose the mixing module IVAR.TV3-300 DN 40?
When the water temperature in the circuit needs to be controlled – for example with underfloor or wall heating, or with a heat source of fluctuating temperature such as a solid-fuel boiler. For direct distribution without mixing, the unmixed IVAR.S-300 module is used.

Is the valve actuator included?
No, the IVAR.SERVOPOHON TV3 actuator is ordered separately – as a 230 V version with 3-point control (IVA20317350) or a 24 V version with 0–10 V control (IVA20317351).

Is the circulation pump part of the module?
No, version IVA49043610 is supplied without a pump and is prepared for a single or twin circulation pump. The version with the DAB.EVOPLUS B 120/250.40 M pump has the code IVA49043610DAB.

Which manifold does the module connect to?
To the IVAR.HC-DN 40 horizontal distribution manifold, either directly or via IVAR.CONNECTA reduction sets. Fixings including gaskets are included.
