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
– 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 ?
Please check the speed control of your application first ( is it PWM or 0-10V , LONGWELL’s all series of Centrifugal fans support 0-10V or PWM and RS485 internet Protocol ) for more details please contact us for professional engineer service
Q4. Life span of this kind of Centrifugal fans ?
Longwell EC external rotor motor surpasses efficiency class IE4, magnets with no rare earths, maintenance-free ball bearings (sealed) with long-term lubrication, theoretical nominal service life of at least 40,000 hours of operation, installation with horizontal and vertical motor shaft; soft start, integrated current limitation. Integrated electronics, quiet commutation logic;
100 % speed controllable; control signal 0-10 V DC / PWM; tach output.
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 ?
Yes ,sure .
