Circulation unit, Constant temperature
GFA200, GFA300
- Thermostatic constant temperature control
- Desired mixing temperature set between 20°C and 55°C
- Available in 3 sizes: DN20, DN25, DN32
- 3 different high efficiency circulation pumps
- High class insulation shell
- Pretested and ready to use
- Compact design
The ESBE series GFA200 and GFA300 are circulation units equipped with thermostatic mixing valves. They are designed for heating circuits where a constant temperature control is required. Equipped with two shut-off valves with thermometers, check valve, high class insulation shell and high efficiency circulation pump.
The GFAx00 is delivered with a 3-way thermostatic mixing valve for constant temperature control of the heating circuit. The thermostatic mixing valve has adjustable temperature setting in the range of 20°C – 55°C.
The series GFA200, with very compact dimensions, are available in DN25 and DN32 and are equipped with either a Wilo or Grundfos pump.
The series GFA300 are available in DN20 and are equipped with a Wilo pump.
