Carrier is offering an electronically commutated motor (ECM) direct-drive fan option for the Aero® 39M commercial air handler product line. According to company officials, adding the new ECM fan option enables customers to further improve the system’s energy efficiency. Onboard electronics determine the position of the rotor, which then provides an electronic pulse to actuate the motor windings.
Cleaver-Brooks has launched the ClearFire®-CE (CFC-E) condensing boiler. The company says the boiler can achieve up to 99% efficiency due to its enhanced AluFer® firetube heat exchanger and dual temperature returns. When utilized, dual temperature returns increase condensing in a hot water boiler, raising efficiency by 6% or more compared to a traditional single-return design, according to officials.
