Pump group Termojet with actuator-controller A-413 1" FT in EPP BLACK thermal insulation without pump PG-48EPPA

Pump group NG-48A with controller actuator — a Termojet 1″ female thread unit with a three-way mixing valve and the A-413 servo actuator-controller in EPP BLACK thermal insulation. The group automatically controls the heat-carrier temperature in the circuit, and a separate boiler room automation system is not required for this: the controller is already included.

Operating principle: the A-413 electric actuator (230 V supply, 3-point ON/OFF control) turns the three-way mixing valve and meters the mixing of the cooled return line into the supply. The actuator torque is 6 Nm, full 90° travel — 120 seconds, protection class IP42, CE and RoHS certificates. Unlike a thermostatic valve with a fixed mechanical setting, the servo actuator provides controlled, smooth regulation of the circuit temperature.

Application scenarios: underfloor heating, radiator circuits with a variable temperature curve, the piping of solid-fuel and gas boilers — anywhere automatic control of the supply temperature is needed. The group is especially suitable in low-temperature systems with a heat pump, where the accuracy of the supply temperature directly affects efficiency — see Termojet heat pumps. If a mirrored layout is required, there is a left version — pump group NG-48A L with controller actuator.

Advantages of the NG-48A from Termojet:

• A-413 servo actuator-controller included — automatic control at no additional cost;
• EPP BLACK thermal insulation with seats for the fittings — minimal heat loss;
• unit assembled and tested at the factory — quick installation;
• Ukrainian manufacture, manufacturer's warranty, available in stock.

Technical specifications: connection 1″ female thread, maximum flow rate Qmax 6.3 m³/h, operating pressure up to 6 bar, height 353 mm, width 261 mm. Circulation pump fitting length — 130 mm; the pump is purchased separately — we recommend the Termojet APE 25-60 pump (130 mm). Simpler models with a thermostatic valve — in the catalog of Termojet pump groups.

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

Frequently asked questions

How does the NG-48A differ from a group with a thermostatic valve?
The thermostatic valve has a fixed mechanical setting, while the A-413 servo actuator controls the valve electrically — the circuit temperature is regulated automatically, without manual readjustment.

Are the actuator and valve included?
Yes, the three-way mixing valve with the A-413 controller actuator (230 V, 6 Nm, IP42) is already installed; only the 130 mm circulation pump is purchased separately.
