- High-efficiency circulator ALPHA SOLAR
High-efficiency circulator ALPHA SOLAR for use in solar thermal systems with variable or constant volume flow. However, high-efficiency pumps with electronically commutated motors (ECM), such as the ALPHA SOLAR, must not be regulated via an external speed controller that changes or varies the supply voltage.
The speed can be regulated via a pulse width modulated signal (PWM signal) supplied by the solar system control to optimize solar energy yield and system temperature. This also significantly reduces the power consumption of the pump.
If no PWM signal is available, the ALPHA SOLAR can be set to one of 4 constant speeds. The pump is then only switched on and off by the controller.
