New Armstrong high efficiency circulators with ECM motor technology

Armstrong has released two new COMPASS R high efficiency models with ECM motor technology for up to 80% energy savings. Featuring an air-cooled ECM motor and advanced Design Envelope variable speed technology, the new COMPASS R20-35 and R40-45 circulators can replace many competing models with bolt-for-bolt connection capability, the company noted. The new COMPASS R models cover a wide performance range and are energy efficient upgrades for two and three-piece and wet rotor circulators.
