Energy efcient & environmentally friendly fans The products in this leaet are equipped with EC-motors. ECtechnology is intelligent technology, using integral electronic control to ensure that the motor always runs at optimal load. What can EC achieve? EC-fans are favoured for their economical use of energy and simplication of control. EC-fans are driven by energy-saving motors with electronic control (commutation unit) ensuring optimal operating efciency. According to their design principle, these are synchronous motors, which run without slip and therefore no slippage losses occur. An...
