What is EC Technology ?
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds.
The motor runs on a DC voltage, but with a single phase 230VAC or three phase 400VAC supply. The motor
incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to
make room for an electronic PCB board which includes power transformation AC to DC, as well as the controls.
Benefits
Energy savings : Minimum power consumption & better efficiency than AC equivalent
Control : 100% speed controllable, not frequency dependant. Can be set up for constant airflow or pressure
applications, 0-10VDC or PWM control signal.
Low motor temperature : For longer lifetime than AC equivalent
Simplicity : Electronic & power transformation are completely integrated within the motor

Benefits of EC Fans
The benefits of EC fans can be measured by comparing 2 backward curved centrifugal motorised impellers (from
manufacturer Rosenberg), one in AC and the other in EC.

Point b : Speed reduced to 75% of volume on point a (1287m/h at 280Pa). Typically the case in an application where a night time set
back system is in place (Point a : full ventilation when building is occupied during the day).
Point c : In the case of a filtered application, Position against a clean filter (point a : Dirty filter) Please note that all the data on the AC
fans exclude any power used and heat loss generated by the speed controller or inverter control, which tends to increase as the speed of
the fan is driven down.

Speed
The VGCD7 200 (curve 1) offers a higher rotational speed than the AC equivalent (Curve 2), which is limited to 50Hz asynchronous
speed (2645rpm). Consequently, the maximum pressure of the EC is 67% higher than the AC, and the maximum airflow 34%
higher than the AC.

Fitted with backward curved motorised impellers
Diameter 315 to 630mm
Airflows up to 15,500m/h
Side panels are removable so the discharge is
possible in any direction.
