High efficiency electronic circulator for solar thermal systems


DESIGN
Taco ES2 SOLAR is a wet rotor high efficiency circulator, driven by a permanent magnets synchronous motor (PM motor) controlled by an on board inverter. The motor is protected against overload thanks to a thermal protection and an automatic electronic release function of the rotor. No external protection is required. Operated by selector technology. LED user interface.

APPLICATION
Renewable energy solar thermal systems, biomass boilers and hot water heating systems of any kind.

PRODUCT FEATURES AND BENEFITS
• Very high degrees of efficiency due to Taco permanent magnets motor
