Manifold Termojet in thermal insulation 4+1 up M42U125(200)

Distribution manifold K42V.125(200) — a Termojet unit with thermal insulation for distributing heat-transfer fluid to four main circuits plus one additional outlet, all outlets facing upward. Flow capacity up to 72 kW at ΔT=10 °C and up to 145 kW at ΔT=20 °C, maximum flow rate Gmax 7.2 m³/h — designed for medium- to large-scale residential boiler rooms.

The boiler-room manifold is structurally a twin-header: supply line and return line in one body; heat-transfer fluid from the heat generator (boiler connection 1¼″) is evenly distributed to four circuit outlets 1″. Centre-to-centre distance between ports — 125 mm, the industry standard — Termojet pump groups mount directly without adapters. Each outlet carries its own pump group at its own temperature level: with a mixer for underfloor heating, straight for radiators or DHW. Additional equipment connection female thread ½″ provided.

Top outlets are convenient when pump groups and pipework run above the manifold — the typical layout of boiler rooms with elevated equipment mounting. Application areas: a house with four or more circuits (multi-zone underfloor heating, radiators, DHW, pool or ventilation), medium-capacity commercial facilities. For hydraulic separation in the boiler room, a hydraulic separator GS-26 1¼″ is installed before the manifold — its connection size matches the boiler connection. NG-46 pump groups with thermostatic valve or straight pump groups are installed on the outlets. If the system is supplied by a heat pump — see Termojet heat pumps.

Advantages of the Termojet K42V manifold:

• four main circuits + additional outlet in one body — compact piping without unnecessary tees;
• 125 mm standard — full compatibility with Termojet 1″ pump groups without adapters;
• thermal insulation jacket and wall-mounting brackets included in the delivery set;
• Ukrainian manufacture: competitive price, stock availability, manufacturer's warranty.

Technical specifications: number of outlets — 4+1 (top), 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″, centre-to-centre distance — 125 mm. Other configurations — in the Termojet distribution manifold catalogue.

Frequently asked questions

What does the 4+1 configuration mean?
Four main outlets with 125 mm centre-to-centre spacing for pump groups plus one additional outlet — for example, for an indirect-fired water heater without a separate pump group.

Is a hydraulic separator needed with this manifold?
If pump groups with separate pumps are connected to the manifold — a hydraulic separator is required: it will make the circuits independent and protect the boiler. The alternative is a KGS-series manifold with a built-in hydraulic separator.
