B & G ecocirc e3 with ECM Technology (Electronically Commutated Motor)
Bell and Gossett’s ecocirc pumps were introduced over the last few weeks. We promised to explain how the ECM technology provides more efficiency than standard induction motors. Let’s talk about the difference between a standard induction motor vs. a permanent magnet motor. With an induction motor, stator windings are arranged around the rotor so that when they’re energized, they create a rotating magnetic field.
Let us take some time to answer YOUR questions…
We received a great deal of questions from last week’s Monday Morning Minutes on the Bell and Gossett Ecocirc domestic water inline pump. Two of the most asked questions were; Why is more reliable? And How does it save energy? The ECOCIRC is more reliable because there are less moving parts. Here is a brief description.
NEW PRODUCT: Energy Efficient Ecocirc 19-14 Auto & Vario Heat Circulators
We are very pleased to announce the addition of the new ecocirc 19-14 heating circulators to our line of energy efficient products. As with the rest of the ecocirc line, this new offering also utilizes Electronically Commutated/Permanent Magnet motors, which by design are more efficient than permanent split capacitor induction motors. This technology also offers more flexibility than standard motors allowing us to add features via software logic rather than hardware that would otherwise add cost.
