Variable Speed Blower: these motors redefines comfort and efficiency by incorporating GE ECM^TM Blower Motor Technology in our equipment. These systems feature: more even temperatures, better indoor air quality, precise humidity control, quieter operation and lower utility bills.

Features and Benefits of the ECM 2.3

• Ultra-high efficiency
  ECM 2.3 efficiencies are as high as 82%. At full load the ECM 2.3 is 20% more efficient than a standard induction motor. At low speed the ECM is over 30% more efficient than a standard induction motor. On constant fan speed, the ECM consumes 60-80 Watts as compared to 400 watts for the induction motor. What's more, its permanent magnet, DC design allows it to maintain its efficiency over its wide speed range.
• Self regulating constant airflow
  Unlike a conventional blower motor, which is designed to operate at one speed, the GE ECM variable -speed motor can run in a wide range of speeds. That's important because blowers need to adjust speed to deliver the airflow needed by the system. GE's patented constant airflow technology can be programmed to deliver constant airflow into a wide range of external static pressures in an air distribution system. This is all accomplished without the use of external sensors. Some benefits of constant airflow: precise air flow for multi stage equipment, improved air distribution throughout the static pressure range, improved indoor air quality with the use of high efficiency air filters and low speed constant fan operation which not only saves money but lessens the temperature stratification that can be common in multilevel homes.
• Low Audible noise
  The most frequent praise given ECM powered systems by customers is how quiet they are. The GE patented resilient rotor construction effectively eliminates noise transmitted through the shaft. The ECM's ability to be programmed to slowly ramp up to speed eliminates the abrupt change in sound found when an induction motor HVAC system cycles on and off. Hydro-Temp comfort systems are designed to take advantage of the ECM's low speed efficiency at first and second stage operation and continuous fan speeds, further reducing audible noise.
