Manifold Termojet in thermal insulation 2+1 down M22D125(200)

Distribution manifold K22N.125(200) — a Termojet unit with thermal insulation in a 2+1 configuration with bottom outlets for heating systems where the heating fluid must be distributed to several consumers with different parameters. Rated for 72 kW at ΔT=10 °C and 145 kW at ΔT=20 °C — the typical output of a private-house boiler room.

The manifold operates as a double header: the supply line and return line are combined in a single body; heating fluid from the boiler (connection 1¼″) is distributed to circuits with 1″ outlets to which pump groups are attached. The centre-to-centre distance between stubs is 125 mm, the industry standard, so Termojet pump groups fit without adapters. A connection for auxiliary equipment G ½″ is provided — for example, for a pressure gauge or sensor.

Bottom outlets are chosen when the circuit pipework runs below the manifold or when it is more convenient to hang the pump groups beneath the header — a typical solution for boiler rooms with a wall-mounted boiler above the manifold. Scenarios: underfloor heating + radiators, radiators + DHW boiler, and also low-temperature systems with a heat pump — see equipment on the Termojet heat pump page. Connect the underfloor heating circuit via the NG-46 L pump group with thermostatic valve 25–55 °C.

Advantages of the Termojet manifold:

• 125 mm standard — direct compatibility with Termojet 1″ pump groups;
• thermal insulation — minimum heat losses in the boiler room;
• wall-mounting brackets included in the delivery set;
• Ukrainian manufacture: affordable price, availability, manufacturer's warranty.

Technical specifications: number of outlets — 2+1 (bottom), 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 connections — 1″, centre-to-centre distance — 125 mm.

The same configuration with top outlets — manifold K22V.125(200); all versions are available in the Termojet distribution manifold catalogue.

Frequently asked questions

What does the 2+1 formula mean?
Two main outlets with 125 mm centre-to-centre spacing for pump groups, plus one additional outlet — for example, for an indirect heating boiler.

When should you choose bottom outlets?
When circuit distribution runs below the manifold or there is little space above it — pump groups are compactly arranged beneath the header.
