Manifold Termojet in thermal insulation 3 up + 2 down M51UD125(100)

Manifold K51VN.125(100) — a single-beam Termojet distribution unit in thermal insulation for boiler rooms where wall space is limited. Five outlets — 3 up + 2 down — allow up to five heat consumers with different parameters to be connected, while the single-beam design makes the unit noticeably more compact than a classic double manifold.

Operating principle: the boiler supply and return lines connect to a single beam inside which a baffle is installed — it directs the flows so that each circuit receives heat carrier from the supply and returns the cooled carrier to the return. The centre-to-centre distance of the circuit connection ports is 125 mm, the industry standard, so Termojet 1″ pump groups mount directly without adapters.

Application areas: boiler rooms of private houses with multiple circuits — underfloor heating, radiators, DHW boiler, ventilation; retrofits where a new manifold must fit into a tight space. The underfloor heating circuit is connected via the NG-46 pump group with thermostatic valve 25–55 °C, and hydraulic independence of multiple pump circuits is ensured by the hydraulic separator GS-26 1¼″. The compact single-beam layout is also convenient for pipework of low-temperature systems with a heat pump — see Termojet heat pumps.

Advantages of the Termojet single-beam manifold:

• one beam instead of two — minimum unit depth and height;
• five outlets in two directions — flexible arrangement of pump groups;
• thermal insulation and wall-mounting brackets included in the delivery set;
• Ukrainian manufacture: competitive price, availability, manufacturer warranty.

Technical specifications: number of outlets — 3 up + 2 down, maximum 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 models are available in the Termojet distribution manifold catalogue.

Frequently asked questions

How does a single-beam manifold differ from a double-beam one?
Supply and return are separated inside a single beam using a baffle — the unit is more compact while the heat distribution function remains the same.

Is the manifold compatible with 125 mm pump groups?
Yes, the centre-to-centre distance of the ports is 125 mm: Termojet 1″ groups, including NG-46 with a thermostatic valve, mount directly.
