Manifold Termojet in thermal insulation 4+1 up+down M42UD150(300)

Manifold K42VN.150(300) — a Termojet unit with thermal insulation for powerful boiler rooms: configuration 4+1 with combined upward and downward outlets, flow capacity up to 175 kW at ΔT=10 °C and up to 350 kW at ΔT=20 °C. This is a solution for facilities where four or more consumers are supplied from a single heat source.

The boiler room manifold operates as a double comb: supply and return lines in one housing, the heat-carrier from the boiler (2″ connection) is distributed to circuits with 1¼″ outlets. The combined arrangement of upward and downward outlets allows compact arrangement of pump groups in two tiers and reduces pipe route lengths. Centre-to-centre spacing of circuit connection nozzles — 150 mm, for increased-size pump groups.

Applications: boiler rooms of commercial and industrial facilities, multi-circuit systems of large buildings, boiler cascades, systems with buffer tanks. Powerful direct pump groups are installed on the circuits — for example, pump group NG-51.150 1¼″ up to 85 kW. Hydraulic independence of the boiler circuit in systems of this capacity is ensured by a hydraulic separator GS-28 2″ with the same connection size.

Advantages of the Termojet manifold:

• 4+1 outlets in two directions — compact pipework even in a confined boiler room;
• boiler connection 2″ — flow capacity reserve up to 350 kW;
• thermal insulation and wall mounting brackets included in the delivery set;
• steel housing, own production in Ukraine, manufacturer's warranty.

Technical specifications: number of outlets — 4+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.

Smaller 2+1 and 3+1 configurations in the 125 mm standard — in the Termojet manifold catalogue.

Frequently Asked Questions

Which pump groups should be installed on this manifold?
Increased-size 1¼″ pump groups for 150 mm centre-to-centre spacing — for example, the direct NG-51.150 with capacity up to 85 kW per circuit.

Is a hydraulic separator needed for such a system?
Yes, hydraulic separation is required for five pump circuits: the hydraulic separator GS-28 2″ will make the circuits independent and stabilise the operation of the boiler or cascade.
