Manifold Termojet in thermal insulation 5+1 down M52D125(200)

The K52N.125(200) manifold is a Termojet insulated unit for multi-circuit boiler rooms: the 5+1 configuration with downward outlets allows up to six heat consumers with different parameters to be connected from a single source. Flow capacity — up to 72 kW at ΔT=10 °C and up to 145 kW at ΔT=20 °C.

The operating principle is that of a twin manifold: the supply and return lines are housed in a single body, and the heat-transfer fluid from the boiler (1¼″ connection) is distributed to circuits via 1″ outlets. The centre-to-centre spacing of the ports is 125 mm, so Termojet pump groups mount directly. A G ½″ auxiliary connection is provided for a pressure gauge, sensor, or air vent.

Downward outlets are chosen when the circuit pipework runs below the manifold or when there is little space above the header — typical for boiler rooms with a top-mounted boiler. Use cases: a large house with underfloor heating in several zones, radiators, and a domestic hot-water cylinder; small commercial premises with ventilation circuits. Floor zones are connected via the NG-46 pump group with thermostatic valve. With five or six pump circuits, a GS-26 hydraulic separator 1¼″ before the manifold is mandatory. For multi-zone heat-pump systems, this header is a convenient distribution centre — see Termojet heat pumps.

Advantages of the Termojet manifold:

• six outlets in one body — compact pipework for a multi-circuit boiler room;
• 125 mm standard — compatibility with pump groups without adapters;
• thermal insulation and wall-mounting brackets included;
• manufactured in Ukraine — competitive price, stock availability, manufacturer's warranty.

Technical specifications: number of outlets — 5+1 (downward), maximum capacity 72 kW at ΔT=10 °C and 145 kW at ΔT=20 °C, maximum flow rate Gmax 7,2 m³/h, boiler connection — 1¼″, heating circuit connection — 1″.

Frequently asked questions

How many consumers can be connected?
Up to six: five main outlets with 125 mm centres for pump groups, plus one auxiliary outlet.

Who should choose downward outlets?
Boiler rooms where the pipework runs below the manifold, or where it is more convenient to position the pump groups beneath the header.
