Bell & Gossett introduced the new ecocirc® 19-16, a variable speed ECM circulator with onboard intelligence that automatically adjusts pump performance to ensure the highest efficiency over a wide operating range. Designed to be set once and forgotten, the ecocirc® 19-16’s built-in intelligence supplies the motor with the precise frequency and voltage for optimum performance. The permanent magnet in the motor means there is no power wasted to magnetize the rotor and ensures the motor delivers superior starting torque and energy efficiency compared to standard induction motor circulators, said company officials. Key features include true variable speed, sensorless operation, pump and motor protection, anti-block technology, and more.
