FAQ

Q1.Why the Ec centrifugal fan is much efficiency than Ac centrifugal fan ?

- Longwell EC fans always operate in the correct direction ;

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 ?

Yes , Longwell can provide some speed regulator solutions according customer's reguirements such as .The RM-ECi controller is for use with the full range of ebm-papst EC fans. Powered by the 10VDC output fromthe motor, it provides infinitely variable, manual speed control between 0% and 100%Can control multiple fans running at the same speed

- 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 ?
