“EC Fan Technology is a fairly new technology that has hit the HVAC market full force! These fans replace the common bulky Variable Frequency Drive (VFD) with an integrated controller on the motor.” ~ Brennan Landry, Design Engineer, Custom Air Products & Services, Inc.
The “electronically commutated” fan or EC Fan has a brushless direct current motor with permanent magnets feed off of alternating current then rectifies the current to direct current.
These motors have a high efficiency rating and works great in applications where a VFD would have been used.
Other popular features of the EC fans are the use of Modbus and BACnet controls, ease of plug and play installation and the low noise levels makes this fan/motor selection a wise choice.
Installing EC Fans into our equipment allows us to reach a higher Energy Efficiency Ratio (EER) on our custom CAPS units.
