Manifold Termojet in thermal insulation 3+1 down MHS32D125(200)

Manifold with hydraulic separator KGS32N.125(200) — a compact boiler-room piping assembly from Termojet: a distribution manifold with 3+1 circuits with bottom outlets and a built-in hydraulic separator GS-26 in a single body. Four consumers, hydraulic isolation of the boiler and heat-carrier purification — all in one unit instead of three separate ones.

How it works: the hydraulic-separator section creates a low-pressure-loss zone, so the boiler pump and the circuit pumps operate independently — without mutual interference or flow-rate fluctuations. The manifold section then distributes flow to the circuits with a centre-to-centre distance of 125 mm, matching Termojet pump groups. The built-in air separator vents gases to the air vent (connection: female thread ½″), and the dirt trap settles sludge that is drained via a ½″ valve — less noise, corrosion and pump wear.

The typical 3+1 scenario — a house with three main circuits: underfloor heating, radiators, DHW boiler, plus an extra outlet for a fourth consumer. The floor heating circuit is connected via the NG-46 pump group with thermostatic valve 25–55 °C. Thanks to full hydraulic separation, the unit is also ideal for heat-pump piping with multiple circuits — see Termojet heat pumps. If you only have two circuits, the smaller model is sufficient — KGS22N.125(200).

Advantages of KGS from Termojet:

• manifold + hydraulic separator + air and sludge separation in one body;
• saves space, pipes and fittings compared to separate units;
• thermal insulation and wall-mounting brackets included in the delivery set;
• Ukrainian manufacture: competitive price, availability, manufacturer's warranty.

Technical specifications: number of outlets — 3+1 (bottom), maximum output 60 kW at ΔT=10 °C and 95 kW at ΔT=20 °C, maximum flow rate Gmax 6,35 m³/h, boiler connection — 1¼″, heating circuit connections — 1″, centre-to-centre distance — 125 mm.

Frequently asked questions

How many consumers can be connected to the KGS32N?
Four: three main outlets at 125 mm centres for pump groups, plus one additional outlet — up to 60 kW total at ΔT=10 °C.

When should I choose a KGS instead of a separate hydraulic separator and manifold?
When the boiler-room configuration is standard and space is limited: the KGS is cheaper and faster to install than two separate units with the piping between them.
