Manifold Termojet in thermal insulation 3 up + 1 down M41UD125(100)

Manifold K41VN.125(100) — a new-design Termojet distribution unit in XPE thermal insulation with a non-standard configuration: 3 outlets up + 1 down. This layout allows three main circuits with upward routing and one circuit with downward routing to be connected from a single unit. Capacity — up to 25 kW at ΔT=10 °C and up to 50 kW at ΔT=20 °C.

Design: double manifold — supply and return lines in a single body. Boiler and consumer connection — 1″, centre-to-centre distance of ports — 125 mm, the standard for Termojet 1″ pump groups. The asymmetric outlet arrangement (3+1) allows the manifold to fit optimally in boiler rooms where most circuits run upward but one runs downward or sideways. XPE insulation protects against heat losses.

Application areas: boiler rooms of private houses with four circuits — for example, three underfloor heating zones and one radiator or boiler circuit in different routing directions. Suitable for systems up to 25/50 kW. Termojet pump groups are mounted on the outlets; if the system has multiple pumps, install a hydraulic separator GS-25 1″ before the manifold — its connection size matches the boiler connection of this manifold.

Advantages of the K41VN from Termojet:

• non-standard combination 3 up + 1 down — precise match to the routing configuration;
• 125 mm standard — full compatibility with Termojet pump groups;
• XPE insulation and 3-year warranty;
• new design (new model) — improved connection quality and reliability.

Technical specifications: type — 3 outlets up + 1 down, boiler connection — 1″, consumer connection — 1″, centre-to-centre distance — 125 mm, capacity 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C, XPE insulation, 3-year warranty.

Other configurations with outlets up, down, or up+down are available in the Termojet distribution manifold catalogue.

Frequently asked questions

How does the new design differ from the old SK-492.125?
Improved connection design and XPE insulation instead of the older material. The part number and mounting dimensions are compatible — it replaces without changing the pipework.

Are Termojet 1″ pump groups suitable for this manifold?
Yes, the 125 mm centre-to-centre distance is the standard for NG-46, NG-47, NG-48, and other Termojet 1″ pump group models.
