Pump group Termojet with actuator-controller A-413 1" FT in thermal insulation without pump PG-48A (28)

Pump group NG-48A with drive-controller A-413 — a Termojet unit with mixing assembly for circuits requiring automatic heat carrier temperature control without boiler room automation. The built-in actuator-controller independently manages the three-way valve; the XPE thermal insulation casing reduces heat losses. Right-side supply line connection.

Operating principle: the three-way mixing valve blends cooled return water into the supply, and drive-controller A-413 rotates it — 230 V power supply, 3-point ON/OFF control, torque 6 Nm, full 90° stroke in 120 seconds, protection class IP42, CE and RoHS certified. Thanks to the built-in controller, the group independently maintains the set circuit temperature — no separate automation unit needs to be purchased. Unlike groups with a thermostatic valve, the temperature is set directly on the controller and changes smoothly across the entire operating range — without replacing the thermostatic head or manual seasonal adjustment.

Applications: underfloor heating, radiator circuits with reduced temperature, piping for solid-fuel and gas boilers requiring smooth automatic supply temperature adjustment. The group also performs well in low-temperature systems with a heat pump — see Termojet heat pumps. For a mirror-image boiler room layout, the pump group NG-48A L with drive-controller (left-hand version) is available.

Advantages of NG-48A from Termojet:

• automatic temperature control "out of the box" — no separate boiler room automation required;
• drive-controller A-413 with CE and RoHS certification;
• XPE thermal insulation casing — minimal heat losses from the unit;
• Ukrainian manufacture, competitive price and manufacturer's warranty.

Technical specifications: connection 1″ female thread, maximum flow rate Qmax 6.3 m³/h, working pressure up to 6 bar, dimensions 353×261 mm. Circulation pump installation length — 130 mm; pump not included — the energy-saving Termojet APE 25-60 pump (130 mm) is suitable.

Groups with thermostatic valve and straight models — in the Termojet pump groups catalogue.

The group is equipped with drive-controller Termojet A-413 with integrated temperature sensor — it automatically controls the three-way mixing valve according to the set programme, maintaining a stable supply temperature.

Frequently Asked Questions

Is separate automation required to control the group?
No. The drive-controller A-413 is built into the group: it independently rotates the three-way valve and maintains the set heat carrier temperature in the circuit.

What pump is suitable for NG-48A?
A circulation pump with a 130 mm installation length — for example, the energy-saving Termojet APE 25-60 (130 mm). The pump is purchased separately.
