Manifold Termojet in thermal insulation 2+1 up+down M22UD150(300)

Distribution manifold K22VN.150(300) — a Termojet unit with thermal insulation for high-capacity boiler rooms: boiler connection 2″, circuits 1¼″, capacity up to 175 kW at ΔT=10 °C and up to 350 kW at ΔT=20 °C. The 2+1 configuration with combined upward and downward outlets provides compact pipework distribution even in limited wall space.

Operating principle: supply and return lines are combined in a single housing; heat carrier from the heat generator is distributed to consumers with different parameters, and oversized pump groups are attached to the outlets. Centre-to-centre spacing of circuit connection ports — 150 mm, for powerful 1¼″ groups such as NG-51.150. The combined outlets allow circuits to be distributed across two tiers, reducing pipe run lengths.

Applications: commercial and industrial facilities, large buildings with powerful radiator branches, boiler cascades, systems with buffer tanks. Hydraulic independence of the boiler circuit in systems of this scale is ensured by the hydraulic separator GS-28 2″ with the same connection size. For large-area facilities on a heat pump cascade, this manifold is the foundation of flow distribution: see Termojet heat pumps.

Advantages of the Termojet manifold:

• 2″ boiler connection — capacity reserve up to 350 kW;
• upward and downward outlets — flexible arrangement of pump groups across two tiers;
• thermal insulation and wall-mounting brackets included in the delivery scope;
• steel housing manufactured in Ukraine, manufacturer's warranty.

Technical specifications: number of outlets — 2+1 (upward + downward), 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″, heating circuit connection — 1¼″, centre-to-centre spacing — 150 mm.

Frequently asked questions

For which systems is this manifold designed?
For boiler rooms up to 175 kW at ΔT=10 °C (350 kW at ΔT=20 °C) with a flow rate up to 17.5 m³/h — commercial facilities, cascades, powerful private residences.

Which pump groups should be installed?
1¼″ groups for 150 mm centre-to-centre spacing — for example, the straight NG-51.150 with a capacity of up to 85 kW per circuit.
