    1. What’s so special about an EC fan?

     

    1.1 EC fans are generally recognised as being the latest thing in energy efficient air movement technology, but what is an EC fan and what makes it so special?

     

    1.2 Although OFAN, the market leader in EC technology, is a China company, EC has nothing to do with the European Community! In this case, EC stands for Electronically Commutated which basically means it is a fan with a brushless DC motor

     

    2. Control options


    To control the motor accurately and efficiently the integrated electronics have to continuously monitor the motor speed and adjust the control input. By making this circuitry available to external sources it’s possible to provide simple speed control options. Dependent on the motor type, any sensor which can provide a 0-10V/PWM or 4-20mA input can be directly connected to provide closed loop control for temperature, pressure or whatever parameter you choose to measure. No need to worry about DC supplies for the sensors either, this is provided by another connection on the motor. In fact, simply connect a potentiometer and you have infinitely variable speed control. No triacs, no frequency inverters and no whining noises! An EC motor under speed control is virtually silent.

     

    3. How does this affect energy efficiency?


    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.

     

    4. AC vs. EC


    The available range of AC input EC fans is expanding all of the time. There are axial and centrifugal fans, forward curved and backward curved, single inlet and double inlet, single phase and three phase and they are often directly interchangeable with their AC equivalents. EC offers the OEM more than just energy-efficiency. It is an opportunity to bring new technology and functionality to their products. With ever-increasing demand for energy efficient systems, when it comes to fan based products, there’s no reason for manufacturers not to have any in their portfolio.

     

    5. OFAN EC products offer you:

     

    Having successfully integrated our advanced electronics into the motor, we realised that it would be a waste to only use it for turning the motor. Our large motors have full programmable networking capability for integration with BMS systems or can be individually programmed with a PDA connected via Bluetooth.

    Constant volume or constant pressure functionality is easily achieved with the connection of one simple sensor or, in some cases, without any external sensors at all. Silent, infinitely adjustable speed control can be as simple as connecting a potentiometer to the motor. Commissioning becomes simplicity itself

     

    6.FAQ

     

    1. Are you a factory or trading company?

    We are a factory which specialized in produce external rotor motor about 10 years. We accept OEM or ODM

    2. How do I know which model I should choose

    Please tell us the fans pressure and airflow and size of fans’ diameter you need. We will study and suggest you the right model.
