Grundfos Alpha2 15/60 Domestic Circulator Bare Pump - High Efficiency A Rated
The Grundfos ALPHA2 L is an advanced energy efficient domestic circulator that meets EuP legislative requirements. This makes it an ideal choice for a variety of domestic circulation heating systems.
The ALPHA2 L achieves the highest possible energy savings in comparison to older technology fixed speed pumps. The reduction in power consumption has been achieved by using the latest permanent magnet motor technology and this power consumption can be as low as 5 watts. The variable speed modulating modes allows the pump to match its performance to the system requirements, helping to reduce noise when thermostatic valves are closing down. The ALPHA2 L models are simple to install in new or existing systems, and are 130mm between ports.
Features and benefits:
Control of Heating Systems:
The heat requirements of a building vary greatly and today thermostatic radiator valves efficiently control the system output. This can lead to excessive pump pressure and valve noise. ALPHA2 L can not only adapt to these variable conditions but reduce electrical energy consumption.
Fixed Speed Pump Mode:
With a fixed speed pump, as the radiator TRV’s close, the system resistance increases causing an increase in pump pressure which can lead to TRV noise.
Pressure Controlled Mode:
As the TRV’s close the pump pressure is controlled according to the selected mode. At the reduced pressure the TRV’s then re-adjust to maintain the required output. The pump pressure reduces radiator valve noise and power consumption.
