Pump group Termojet with mixer 1" FT in EPP BLACK thermal insulation without pump PG-48EPPL

Pump group with mixer NG-48 L in EPP BLACK casing — a Termojet unit with a three-way valve and 220 V electric actuator for circuits where heating medium temperature is controlled by the boiler room automation. The EPP BLACK version differs from the standard one by higher-quality thermal insulation and a pump mounting length of 180 mm. Circuit capacity — up to 40 kW at ΔT=20 °C.

Operating principle: the boiler room controller drives the actuator, which opens or closes the return line of the three-way valve, precisely metering the mixing of cooled heating medium. This implements weather-compensated control, protection of underfloor heating from overheating, and efficient circuit loading in various boiler operating modes. Valves with 0–120 °C thermometers on supply and return, built-in check valve and EPP BLACK thermal insulation casing — complete factory equipment.

Applications: underfloor heating with boiler room automation, low-temperature radiator heating with weather-compensated control, heat pump circuits where precise supply temperature is critical for COP. Selecting equipment for low-temperature heating — see Termojet heat pumps. For multiple circuits, choose the manifold K32N.125 3+1 with bottom outlets.

Advantages of NG-48 L from Termojet:

• EPP BLACK casing — improved thermal insulation and resistance to mechanical damage;
• 220 V actuator included, ready for automation connection;
• 180 mm pump mounting — wider choice of circulation pump models;
• own manufacturing in Ukraine, warranty and stock availability.

Technical parameters: maximum capacity 20 kW at ΔT=10 °C and 40 kW at ΔT=20 °C, Kvs 6.3 m³/h, connection to manifold and circuit — 1″ female thread, working pressure up to 6 bar, height 395 mm, width 250 mm, volume 0.34 l. Pump mounting length — 180 mm; pump not included, we recommend the Termojet APE 25-60 circulation pump (180 mm). For connection to a manifold with 1¼″ outlets, use adapter KP125/150.

The NG-48 version with standard insulation for 130 mm pump and other models — in the Termojet pump group catalogue.

Frequently asked questions

What is the difference between NG-48 and NG-48 L?
The difference is in the insulation material (EPP BLACK vs. standard casing) and pump mounting length: 180 mm in the L version vs. 130 mm in the base version. Functionally — identical.

Is the group compatible with Termojet automation?
Yes, the 220 V electric actuator connects to Termojet PROFI PLUS and Termojet LIGHT series controllers with the appropriate outputs for the mixing valve.
