Consisting of small, medium and large sized circulation pumps, the MAGNA3 series includes communication equipment, permanent magnet designed electronic speed control and compact stator motor technology.

MAGNA3 automatically analyzes the heating system, finds the ideal setting and constantly adjusts its performance to changes in demand. Thus, ideal comfort is achieved and energy consumption is minimized. In addition, MAGNA3 pumps are highly compatible, reliable and quiet, long-lasting and maintenance-free. It has infrared (IR) communication feature and can be monitored and controlled from the outside with additional modules.
