Circulation unit

GBA100

The ESBE series GBA100 is a circulation mixing unit which is intended for heating circulations where a flow temperature control and an efficient use of energy are required. Equipped with two shut-off valves with thermometers, check valve, high class insulation shell and high efficiency circulation pump.

The GBA100 is delivered with a bivalent rotary mixing valve and actuator. The Circulation Mixing Unit ensures efficient use of energy thanks to the bivalent rotary mixing valve, as well as the working possibility with most controllers available on the market.
  • Efficient use of energy thanks to the bivalent valve
  • Ready to use with most controllers available on the market
  • High class insulation shell
  • One size fits all – auto adapt

Dimensioning, Pump Capacity diagram
Example: Start with the heating demand of heating circuit (e.g. 25 kW) and move horizontally to the right in the diagram to the Δt = 15°C (temperature difference between flow and return of the heating circuit). Next go up and find working point and read the available pressure of the pump on the left – ∆p = 45 kPa.
