Manifold Termojet in thermal insulation 3+1 down M32D125(200)

Distribution manifold K32N.125(200) — a Termojet unit with thermal insulation for distributing heat-transfer fluid from the boiler to several consumers with different parameters. Configuration 3+1 with bottom outlets is designed for three main circuits with pump groups and one additional outlet; flow capacity up to 72 kW at ΔT=10 °C (145 kW at ΔT=20 °C).

Structurally this is a twin-header manifold: supply line and return line in one body. Heat-transfer fluid from the heat generator enters the manifold through a 1¼″ connection and is distributed to circuits with 1″ outlets to which pump groups are attached. Centre-to-centre distance between circuit ports — 125 mm, the industry standard, so Termojet groups mount directly. Additional equipment connection G ½″ provided — for a pressure gauge or sensor.

Bottom outlets are chosen when the circuit pipework runs below the manifold or when pump groups are more conveniently positioned beneath the header. Typical applications: residential boiler room with underfloor heating, radiators and DHW boiler; multi-circuit low-temperature systems including those with a heat pump — see Termojet heat pumps. If the pipework runs upward, choose the K32V.125 manifold with top outlets; for two circuits the K22N.125 manifold (2+1, bottom) is sufficient.

Advantages of the Termojet manifold:

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

Technical specifications: number of outlets — 3+1 (bottom), 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.

Frequently asked questions

What does the 3+1 configuration mean?
Three main outlets with 125 mm centre-to-centre spacing for pump groups plus one additional outlet for another consumer — for example, an indirect-fired water heater.

Is a hydraulic separator needed in addition to the manifold?
If there are two or more pumped circuits — yes: a hydraulic separator installed before the manifold will make the circuits hydraulically independent and stabilise boiler operation.
