Manifold Termojet in thermal insulation 2+1 down M22D150(300)

Distribution manifold K22N.150(300) — a Termojet unit with thermal insulation for high-capacity boiler rooms: configuration 2+1 with downward outlets, boiler connection 2″ and maximum flow rate Gmax 17.5 m³/h. Capacity — up to 175 kW at ΔT=10 °C and up to 350 kW at ΔT=20 °C. This solution is designed for large residential buildings and commercial facilities where two powerful circuits are sufficient but maximum system throughput is required.

Manifold design: supply and return lines in a single housing with a 2″ boiler connection, heat carrier distribution to 1¼″ circuits. Centre-to-centre spacing of circuit connection ports — 150 mm, requiring oversized pump groups. Additional G ½″ outlet included for connecting auxiliary equipment. Downward outlets — the optimal solution for bottom pipework distribution or limited space above the manifold.

Applications: boiler rooms of large residential buildings and small industrial facilities where two powerful circuits are fed from a single heat source — for example, a large radiator circuit and an underfloor heating system in a multi-storey building. A hydraulic separator GS-28 2″ must be installed before the manifold for hydraulic separation. For heating large buildings with a heat pump, see Termojet heat pumps.

Advantages of the Termojet manifold:

• 2″ boiler connection — maximum capacity up to 350 kW;
• 1¼″ circuit outlets, 150 mm centre-to-centre — for powerful pump groups;
• thermal insulation and wall-mounting brackets included;
• steel housing, manufactured in Ukraine, manufacturer's warranty.

Technical specifications: number of outlets — 2+1, maximum capacity 175 kW at ΔT=10 °C and 350 kW at ΔT=20 °C, maximum flow rate Gmax 17.5 m³/h, boiler connection — 2″, circuit connection — 1¼″, centre-to-centre spacing — 150 mm.

Series 150 models for 3–5 circuits — in the Termojet distribution manifold catalogue.

Frequently asked questions

How does the 150 series differ from the 125 series?
Centre-to-centre outlet spacing of 150 mm versus 125 mm and 1¼″ circuit connection instead of 1″. The 150 series is designed for higher heat carrier flow rates and higher circuit capacities — from 50 kW per circuit and above.

Which hydraulic separator should be installed before this manifold?
GS-28 2″ — its connection size matches the boiler connection of this manifold, and it handles the full flow rate Gmax 17.5 m³/h.
