Manifold Termojet in thermal insulation 2 up + 1 down Mini M31U125(80)

Manifold K31V.125(80) Mini — a compact Termojet distribution unit with thermal insulation featuring combined outlets: 2 upward + 1 downward. Boiler and circuit connections — 1″, capacity up to 25 kW at ΔT=10 °C and up to 50 kW at ΔT=20 °C, maximum flow rate Gmax 5.1 m³/h. The difference from the K22V Mini model lies in the position of the third outlet: it is directed downward, providing greater flexibility in pipe routing.

Structurally — a dual manifold of minimum dimensions: supply and return lines in a single body, two outlets upward and one outlet downward. Center-to-center spacing — 125 mm, the Termojet pump group standard — mounting without adapters. Wall-mounting brackets are included. The thermal insulation jacket reduces heat losses of the unit in the boiler room.

Typical scenarios: underfloor heating and radiator heating upward + DHW boiler or third zone downward; boiler rooms in built-in spaces where pipe routes run in different directions. Combined outlets allow three circuits to be piped compactly without extra elbows and tees. Termojet pump groups are installed on the outlets according to the circuit type: NG-46 with thermostatic valve (underfloor heating) or NG-47 direct (radiators, DHW). If hydraulic separation is required for three pump circuits, consider the KHS22N.125(150) Mini with built-in hydraulic separator.

Advantages of K31V Mini from Termojet:

• combined outlets 2 upward + 1 downward — pipe routing in two directions without extra fittings;
• Gmax 5.1 m³/h — higher flow capacity compared to K22V Mini (2.1 m³/h);
• 125 mm standard and thermal insulation included — fully ready for installation;
• Ukrainian manufacture, competitive price, official manufacturer's warranty.

Technical specifications: outlets — 2 upward + 1 downward, boiler and circuit connections — 1″, maximum capacity 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C, maximum flow rate Gmax 5.1 m³/h, center-to-center spacing — 125 mm. Full model range — in the Termojet manifold catalog.

Frequently Asked Questions

How does K31V Mini differ from K22V Mini?
In the position of the third outlet: in K31V it is directed downward, in K22V — upward. K31V has a higher flow rate: Gmax 5.1 m³/h versus 2.1 m³/h, so K31V is suitable for systems with larger pumps and higher heat carrier flow rates.

Is a hydraulic separator needed for three circuits of this manifold?
Yes, if each circuit has its own pump — hydraulic separation is recommended. A convenient alternative is the KHS22N.125(150) Mini with a built-in hydraulic separator in a single body.
