ECMs and Humidifiers – Are You Up To (Fan) Speed?

Starting July 3rd, the US Department of Energy is requiring a maximum fan energy rating (FER) for furnace fans in order to reduce energy consumption and CO2 emissions. To comply with these regulations, equipment manufacturers are moving to electronically commutated motors (ECMs) as the sole motor type used in furnace production.

This is the perfect time to show how well ECMs and bypass humidifiers perform together.  To answer any questions on the subject, we’ve put together this short presentation about the different furnace motor technologies that exist and which of our humidifier models we recommend for installation with each type.

Check it out and let us know in the comments if there’s anything new you learned, or if you have any more questions. Also, take a look at our Humidifier Regional Application Guide for quick reference. It includes the updated recommendation chart seen at the end of the presentation.
