Product Description

ALPHA SOLAR is a high efficiency circulator with an IEE index ≤ 0.20, ensuring optimal energy consumption, offering flexible solutions for solar thermal systems.

It is designed to work with or without an external PWM (Pulse Width Modulation) speed control signal via cable connection.

Without external regulation, ALPHA SOLAR allows you to select 4 fixed speeds to choose from.

With external regulation, ALPHA SOLAR offers the possibility of varying the flow rate, and thus increasing energy efficiency, through a low voltage PWM signal, controlled by a solar regulator.

If replacing an old generation 230 V solar pump, regulated by phase sections or block modulation, it will be necessary to install a converter between the solar regulator and the ALPHA SOLAR pump to generate a PWM output signal. The impeller is made of corrosion-resistant material.
