Systemair DVN 355EC - Centrifugal roof fan, 120°C continuous, vertical discharge

EC-motors, high level of efficiency Motor outside the air stream 100% speed controllable Integrated motor protection Pre-assembeled isolator is standard Max temperature of transported air 120°C Suitable for coastal applications Vertical exhaust Low sound level Potentiometer included for ease commissioning EC technology is intelligent technology; using integral electronic control which eliminates the slip losses in the motor and ensures that the motor always runs at optimal load and guarantees that the proportion of energy utilized effectively is many times higher and the energy usage considerably lower compared with AC motors. EC fans are notable for their economical use of energy and excellent ease of control. They can be varied in speed to match the airflow demand, and operate at high efficiency levels. For the same air volume, they consume distinctly less energy than AC fan drives. Another special feature of EC fans is their energy-saving potential not only at full load, but especially at part-load. Whe...
