tubra®-PGM / PGR S
Heating circuit groups DN 20
The compact pump groups for mixed and unmixed heating circuits
up to 45 kW heat output.
- large power range up to 45 kW
- progressive mixing characteristic for large flow rate range with optimum control quality (DN 20 kvs = 0 – 4.5 m³/h)
- integrated temperature sensors – position in flow and return
- smooth running ball valves with floating ball
- integrated fitting piece for heat meter or tubra®-mag-jet magnetite separator
- thermal insulation compliant with GEG
- suitable for cooling applications > 14°C due to transparent foil in front of the thermometer openings
tubra® variants DN 20 groups
The compact heating group is available with different pumps.
- Pumps: Grundfos UPM3, Wilo Para and without pump
- Mixer: with and without 3-way mixer
- Actuator:
- 230V 3-point
- 24V, 0-10V
- 230V with constant value control
tubra®-Trio-mat +
tubra®-PGM S
The compact pipe group for one mixed and one unmixed heating circuit with only one pump group.
- direct connection to a heat generator with integrated pump
- compact modular design
- completely pre-assembled for connection to the heating circuit
- lower operating costs, as there is no need for a pump in the unmixed heating circuit
- combination with system separation ensures minimum flow rate
