Manifold Termojet in thermal insulation 4+1 down M42D150(300)

Distribution manifold K42N.150(300) — a Termojet unit with thermal insulation for high-capacity boiler rooms with a 4+1 downward outlet configuration. The 2″ boiler connection and maximum flow rate Gmax 17,5 m³/h provide throughput capacity of up to 175 kW at ΔT=10 °C and up to 350 kW at ΔT=20 °C — four powerful independent circuits from a single unit.

Header construction: supply and return lines in a single body; the heat carrier from the boiler (2″) is distributed to four main circuits (1¼″) plus one additional G ½″ outlet. Centre-to-centre spacing of the circuit connection stubs — 150 mm, so increased-size 1¼″ pump groups are used. Downward outlets are the optimal solution for boiler rooms where the pump groups or pipe runs are below the manifold mounting level.

Application areas: large boiler rooms in residential and commercial buildings with four different-temperature circuits: underfloor heating zones, radiator heating, DHW, ventilation or pool heating. For hydraulic separation in a system of this capacity, the hydraulic separator GS-28 2″ is mandatory — its connection size matches the manifold's boiler connection. If the building is heated by a heat pump, see Termojet heat pumps.

Advantages of K42N.150 from Termojet:

• four powerful 1¼″ circuits from a 2″ boiler connection — ample throughput capacity;
• 150 mm centre-to-centre spacing and downward outlets — for powerful increased-size pump groups;
• thermal insulation and wall-mounting brackets included in the delivery scope;
• steel body, own manufacture in Ukraine, manufacturer's warranty.

Technical specifications: number of outlets — 4+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 connections — 1¼″, centre-to-centre spacing — 150 mm.

Model K42VN.150 with combined up+down outlets and other configurations are available in the Termojet distribution manifold catalogue.

Frequently asked questions

What is the difference between K42N and K42VN?
K42N has all outlets directed downward, K42VN — in two directions (up and down). Choose depending on the boiler room layout and the direction of the pipe runs.

Which pump groups are suitable for this manifold?
Increased-size pump groups with a 1¼″ connection and a design centre-to-centre spacing of 150 mm.
