Variable Speed Blower: Hydro-Temp redefines comfort and efficiency by incorporating Genteq ECMTM Blower Motor Technology in our equipment. The variable speed blower coupled with the Hydro-Temp microprocessor feature: even temperatures throughout the space, better indoor air quality, precise humidity control, quieter operation and lower utility bills.

 

The Hydro-Temp microprocessor sends the variable speed blower motor a
pulse width  signal to control the blower speed.  The Hydro-Temp
microprocessor can be field programmed to deliver 3 blower speeds in heat,
3 blower speeds in cool plus a fan circulation mode.  Other unique features
of the Hydro-Temp microprocessor include slowing down the blower while in
heating to achieve a desired discharge air temperature and if space humidity
is high slowing down the blower in cooling to increase the latent cooling of the
system, if the space humidity starts getting too low the blower can speed up to increase the sensible cooling.

 

Features and Benefits of the ECM

 

* Ultra-high efficiency

 ECM 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.
