FANS AND MOTORS MERGEN units are equipped with directly driven plug fans with EC motor, direct current motors with electronic modulation (EC), high efficiency, thermal protection and integrated speed control. The EC technology guarantees low consumption by controlling its operating point between 10 and 100%. EC motors provide a low noise level which results in better acoustic comfort.
