ALPHA2 is the latest and most innovative member of the Grundfos family of high-quality circulators.
With ALPHA2, you can stop worrying about complicated pump settings. Simply install the pump and leave it in the factory setting, AUTOADAPT. ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand.
Applications
GRUNDFOS ALPHA2 is designed for circulating liquids in heating systems. Pumps with stainless steel pump housing can also be used in domestic hot-water systems.
GRUNDFOS ALPHA2 is suitable for:
- systems with constant or variable flows where it is desirable to optimise the pump duty point
- systems with variable flow-pipe temperature
- systems where night setback is an issue and desired.
Features and benefits:
- Compact design with control box well integrated in the pump head
- AUTOADAPT control mode as default setting, suitable for most applications
- Integrated differential-pressure control (proportional- and constant pressure control)
- A display showing the actual power consumption (P1) in Watt
- Low noise
- High starting torque
- Automatic Night SetBack
- Motor based on permanent-magnet/compact-stator technology
- Integrated frequency converter
- Self-venting pump housing
Applications
Circulation of hot or cold water in:
- Heating systems
- Domestic hot water systems
- Cooling and air-conditioning systems
