The ALPHA1 L, with its compact design, easy installation, and wide range of types, is suitable for most systems where an older, energy-inefficient pump needs to be replaced with a new one. The pump's settings are easy and quick to configure. In addition to standard control modes, the ALPHA1 L also allows performance regulation via a PWM signal.
This is a technically and functionally improved replacement for the ALPHA2 L pumps.
