Manifold Termojet in thermal insulation 3+1 down M32D125(240)

Manifold K32N.125(240) — a Termojet unit with thermal insulation configured as 3+1 with downward outlets for high-capacity heating systems. The boiler connection 1½″ and maximum flow rate Gmax 9.1 m³/h provide a capacity of up to 105 kW at ΔT=10 °C and up to 210 kW at ΔT=20 °C — for mid-capacity residential and commercial buildings.

Manifold design: supply and return lines in a single housing; heat carrier from the boiler (1½″) is distributed to three main circuits plus one additional outlet G ½″. The centre-to-centre spacing of circuit connection ports is 125 mm, so Termojet 1″ pump groups mount directly. Downward outlets are the optimal choice for boiler rooms where circuit pipework runs below the manifold mounting level, or where pump groups are more conveniently positioned beneath the manifold.

Applications: high-capacity boiler rooms in residential and commercial buildings — three circuits for different purposes simultaneously: underfloor heating, radiators, and a DHW boiler or ventilation. For hydraulic separation before the manifold, a hydraulic separator GS-27 1½″ is installed — its connection size matches the boiler connection of this manifold. Termojet pump groups with a standard 125 mm spacing are mounted on the outlets.

Advantages of the Termojet manifold:

• 1½″ boiler connection — increased capacity up to 210 kW;
• 125 mm standard — compatibility with pump groups without adapters;
• downward outlets — convenient connection with bottom pipe routing;
• thermal insulation and brackets included, manufactured by Termojet, warranty.

Technical specifications: number of outlets — 3+1, maximum capacity 105 kW at ΔT=10 °C and 210 kW at ΔT=20 °C, maximum flow rate Gmax 9.1 m³/h, boiler connection — 1½″, circuit connection — 1″, centre-to-centre spacing — 125 mm.

The K32V.125 version with upward outlets and the 150 mm manifold series for higher capacity are available in the Termojet manifold catalogue.

Frequently asked questions

Is this manifold suitable for high-capacity boilers above 100 kW?
Up to 105 kW at ΔT=10 °C and up to 210 kW at ΔT=20 °C — yes. For higher capacities, switch to the 150 mm manifold series with a 2″ boiler connection.

What does "+1" mean in the 3+1 formula?
Three main 1″ outlets with a 125 mm centre-to-centre spacing for pump groups, plus one additional G ½″ outlet for connecting a pressure gauge, sensor, or small consumer.
