Circulation unit, Bivalent function

GBA100

  • 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

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.
