Circulation unit, Fixed temperature
GFF200
- Constant temperature control thanks to the thermostatic valve
- Adjustable flow temperature settings
- 180mm pump ready – be free to use favorite pump manufacturer
- Easy to install with adjustable wall bracket
The ESBE series GFF200 is a circulation mixing unit which is intended for heating circulations where the constant temperature control are required. Equipped with two shut-off valves with thermometers, check valve and high class isolation shell. The GFF200 is delivered with the 3-way thermostatic valve, which provides constant temperature regulation of the heating system and adjustable temperature setting.
The ESBE Circulation Unit GFF200 is ready to work with 180mm pumps. The smart adjustable insulation shell makes it sure that any kind of pump will be isolated in a right way.
