Manifold Termojet in thermal insulation 2 up + 1 down M31UD125(100)

Distribution manifold K31VN.125(100) — a compact single-beam Termojet unit in thermal insulation with outlets 2 up + 1 down. It distributes the heat carrier from the boiler to multiple consumers with different parameters and handles 72 kW at ΔT=10 °C and 145 kW at ΔT=20 °C.

Design feature — one beam instead of two: the supply and return lines of the boiler connect to a common body, and an internal baffle separates the supply and return flows. This makes the unit more compact than the classic double manifold without loss of functionality. The centre-to-centre distance of the circuit connection ports is 125 mm, the standard for Termojet pump groups; wall-mounting brackets are included in the delivery set.

Application scenarios: boiler rooms of private houses with two or three circuits — underfloor heating, radiators, DHW boiler — where compact pipework matters; low-temperature systems with a heat pump — see equipment on the Termojet heat pumps page. Connect the underfloor heating circuit via the NG-46 L pump group with thermostatic valve 25–55 °C.

Advantages of the Termojet single-beam manifold:

• compact body — less wall space than a double manifold;
• outlets on two sides (2 up + 1 down) — flexible positioning of pump groups;
• 125 mm standard — Termojet 1″ groups mount without adapters;
• thermal insulation and brackets included, Ukrainian manufacture, warranty.

Technical specifications: number of outlets — 2+1, capacity 72 kW at ΔT=10 °C and 145 kW at ΔT=20 °C, maximum flow rate Gmax 7.2 m³/h, boiler connection — 1¼″, heating circuit connection — 1″, centre-to-centre distance — 125 mm.

Classic double-beam versions — for example, manifold K22VN.125 with combined outlets — and other configurations are available in the Termojet distribution manifold catalogue.

Frequently asked questions

How does a single-beam manifold differ from a conventional one?
Supply and return are combined in one body with an internal baffle — the unit is more compact and easier to install than a double manifold made of two beams.

Is the manifold compatible with 125 mm pump groups?
Yes, the centre-to-centre distance of the outlets is 125 mm: NG-46, NG-47, and other Termojet 1″ groups install without adapters.
