Manifold Termojet in thermal insulation 3+1 down M32D150(300)

Manifold K32N.150(300) — a powerful Termojet unit with thermal insulation, boiler connection 2″ and configuration 3+1 with downward outlets. Flow capacity up to 175 kW at ΔT=10 °C and up to 350 kW at ΔT=20 °C at maximum flow rate Gmax 17.5 m³/h — a solution for industrial boiler rooms, boiler cascades, and large commercial facilities.

Structurally, the manifold is a double-comb of increased size: supply and return lines in one housing, the heat-transfer fluid from a powerful heat generator (2″ connection) is distributed to three circuit outlets 1¼″ plus one additional. Centre-to-centre spacing between nozzles — 150 mm, designed for pump groups and equipment of increased size. Outlets are directed downward — optimal for boiler rooms where circuit pipe routes run below the manifold level, or where the boiler is located in the upper part of the boiler room.

Applications: industrial boiler rooms and commercial facility boiler rooms (hotels, shopping centres, industrial buildings), boiler cascades from 150 kW, systems with powerful solid-fuel boilers and buffer tanks. For hydraulic separation of a system of this capacity, a hydraulic separator GS-28 2″ up to 250 kW is installed before the manifold — its connection size matches the boiler connection. For systems with powerful heat pumps — see Termojet heat pumps.

Advantages of K32N.150 from Termojet:

• boiler connection 2″ and Gmax 17.5 m³/h — power reserve of 350 kW without flow restrictions;
• downward outlets 1¼″ — convenient routing of powerful circuits in industrial boiler rooms;
• thermal insulation jacket and wall mounting brackets included in the delivery set;
• steel housing, own production in Ukraine, official manufacturer's warranty.

Technical specifications: number of outlets — 3+1 (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

Why does this manifold have 1¼″ outlets instead of 1″?
The increased outlet size corresponds to powerful circuits and pump groups of the 1¼″ series — for example, NG-51.150 up to 85 kW per circuit. For typical residential systems with 1″ pump groups, choose K-series manifolds with 125 mm centre-to-centre spacing.

What is the capacity per circuit with 3+1?
The maximum manifold capacity — 350 kW at ΔT=20 °C — is distributed among the connected circuits depending on their pumps and flow rates. One circuit can receive up to 85 kW when using a 1¼″ pump group.
