Q1.Why the Ec centrifugal fan is much efficiency than Ac centrifugal fan ?
Operate on either 50Hz or 60Hz;
Operate on a wide voltage range(200-277Vsingle Phase&380-480 Vthree phase );
Operates much cooler-longer life ;
Less heat for a refrigeration system to handle (increased refrigeration COP),30 % average energy saving compared to AC technology;
Q2. Does Longwell provide any speed control options for EC FANS ?
– Stepless control knob for infinitely variable speed setting
– Cable entries 4xM16 or M20
– 4mm mounting holes
Q3. how we connect fan unit to our application ,is there a wiring diagram ?
Q4. Life span of this kind of Centrifugal fans ?
100 % speed controllable; control signal 0-10 V DC / PWM; tach output.
Q5. Are there any other AC DC EC centrifugal fans options or solutions for selection ?
