Similar Ebm-Past Ec Centrifugal Fans Fresh Air System Pa66 250mm 280mm

1. The parameters listed in this catalogue were tested under standard condition.(gas density is 1.2KG/m3, temperature is 20℃)

2. The gas transported by the fan should be non-corrosive, non-flammable, non-explosive and non-sticky.

3. Operating conditions: the ambient temperature range should be:-40℃---+60℃, the relative humidity should be less than 90%, the altitude should be less than 1000 meters.

4. The centrifugal fans are divided into levoratation and dextrorotation.

5. You can select the DYF series centrifugal fan model accordingly so that we can customize the corresponding cabinet air-conditioning blowers based on your needs.

6． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation

7． Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs

1. How does this affect energy efficiency?

1. Doubling the speed of a motor increases its power input by a factor of 8 so it’s very wasteful to run a fan faster than is required. If you can tailor the fan speed to match the demand, the potential for energy saving is huge. Even when compared to on/off operation, EC speed modulation is much more efficient.

2. EC fans can also contribute to increasing the overall efficiency of an application. In a cooling system for example, keeping the refrigerant pressure constant rather than having it rise and fall as fans switch on and off has been found to reduce the load on the compressor resulting in even greater energy saving.
