Standard Circulator with High-Efficiency Motor
and EC Technology. The standard circulator is equipped with
a self-protected, high-efficiency motor, using
EC technology for electronic performance regulation
and external regulation via a
PWM1-PWM2 signal.
Features of the GPA Series High-Efficiency Circulators:
The GPA series high-efficiency circulators can
be used in a variety of fields, such as heating,
air conditioning, solar, and geothermal systems.
