ENERGY AND COST SAVING POTENTIAL WHILE EMPLOYING AN EC DRIVEN RUCK AIRMOVEMENT FAN

ruck Air Movement develops highly efficient solutions for ventilation applications. Together with an outstanding aero-efficiency, the use of brushless DC motors ensures the highest overall efficiencies, which show their strength especially in the partial load range.

EC motors are permanent magnet motors in which the unit is electronically commutated. This commutation electronics uses a rectifier to convert the AC mains voltage to DC voltage and then applied controlled to the motor windings. Low winding temperatures and low losses ensure a long lifetime and high efficiencies for EC motors.

In ventilation units, compared to conventional AC motors, the EC motors generally require less power for the same flow rates. A special savings potential is achieved by the EC fans when used in partial load. Here the efficiency loss is much lower in case of EC fans compared to AC fans with similar capacity. With this technology, a more efficient, silent and continuous speed control is possible.
