Manifold Termojet in thermal insulation 3 up + 1 down Mini M41U125(80)

Manifold K41V.125(80) Mini — a compact Termojet unit with thermal insulation featuring combined outlet arrangement: 3 upward + 1 downward. Designed for systems up to 25 kW at ΔT=10 °C and up to 50 kW at ΔT=20 °C — the typical capacity of a residential boiler room. The model was previously produced under article number SK-491.125.

Operating principle: the supply and return lines are combined in a single manifold; the heat carrier from the boiler enters through a 1″ connection and is distributed to four circuits with 1″ outlets. The center-to-center spacing of the ports is 125 mm, the standard for Termojet pump groups, so they mount directly. Wall-mounting brackets are included, and the thermal insulation jacket reduces heat losses of the unit.

Combined outlets are the key feature of this model: three consumers connect from the top, and the fourth from the bottom, which is convenient when one pipe run (for example, to a DHW boiler or a basement circuit) passes below the manifold. Scenarios: underfloor heating, radiators, DHW plus an additional circuit. The manifold is also suitable for low-temperature systems with a heat pump — see Termojet heat pumps. If all pipe runs go upward, choose the manifold K32V.125 for 3+1 circuits upward; the full-size model with two-tier distribution is K22VN.125 with outlets upward and downward.

Advantages of the Termojet Mini manifold:

• combined outlets in two directions — flexible distribution without extra elbows and pipe runs;
• compact body — space savings in a small boiler room;
• 125 mm standard, thermal insulation and brackets included;
• Ukrainian manufacture: competitive price, availability, manufacturer's warranty.

Technical specifications: outlets — 3 upward + 1 downward, maximum capacity 25 kW at ΔT=10 °C and 50 kW at ΔT=20 °C, maximum flow rate 5.1 m³/h, boiler connection — 1″, circuit connections — 1″, center-to-center spacing — 125 mm.

Frequently Asked Questions

Why is a downward outlet needed?
For a consumer whose pipe run passes below the manifold — for example, a DHW boiler in the basement. This reduces pipe length and the number of fittings.

Are Termojet 125 mm pump groups compatible?
Yes, the center-to-center spacing of all outlets is 125 mm: 1″ pump groups mount directly, without adapters.
