2 2 I EC-fans Energy efficient & environmentally friendly fans The products in this leaflet 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 simplification of control. EC-fans are driven by energy-saving motors with electronic control (commutation unit) ensuring optimal operating efficiency. According to their design principle, these are synchronous motors, which run without slip and therefore no slippage losses occur. An excellent solution for demand responsive ventilation systems. Another pro-environmental aspect relevant to air supply and air conditioning equipment in particular is noise level. Here too, the advantage is with EC-motors, which run silently in controlled operating conditions. EC-motors have longer service life due to lower winding tempe ratures resulting in lower wear and tare. EC-motors with integrated electronic control can easily be varied in speed to match airflow demand. For the same air volume, they consume distinctly less energy than AC motors. EC-motors have high energy-saving potential not only at full load, but especially at part-load, where the loss of efficiency is very much lower than with an asynchronous motor of equivalent output. Advantages with EC motors: Up to 9 % higher efficiency than conventional systems Long service life due to small heat losses in the motor Easy to control with -1V DC or PWM signal Low sound level throughout the entire fan performance All control and protection electronics are integrated in the motor, easy connection Ventilation on demand easy to adjust ventilation rate to actual need. The following is included when selecting an EC motor: Overheat protection Overload protection Protection against locked rotor Control electronics Softstart, starts slowly and gradually increases to full speed over a predefin ed time. EC-Vent control Energy efficient ventilation is about designing a system in a smart way, using a fan that has a high efficiency and adjusting the ventilation rate to the actual need, instead of always operating at full capacity, while maintaining good indoor air quality. Today Systemair probably has the widest range of EC fans on the ventilation market, and are happy to introduce a control system that will make it easy for the contractor, installer and end user to achieve Demand Control Ventilation (DCV). The system contains a central control and a room controller that are connected with SELV. (Safety Extra Low Voltage). Built in transformer EC-Vent room unit 24V supply to dampers Built in humidity and temperature sensor in the room controller Ability to connect CO 2 sensor, presence sensor, humidity sensor etc. Possibility to create a week schedule. By using energy efficient EC-fans with intelligent control, your system will meet the ventilation requirements of both new building and refurbishment projects.
