TEKADOOR uses different types of fans depending on the type of unit. Apart from our industrial door air curtains TIC (axial fans) and the recirculating air curtain PREVENT (tangential fans), our other door air curtains use radial fans which can intake air in both directions.
The advantage of this type of fan is that it is relatively quiet and has smaller dimensions. All the fans used by Tekadoor do not just comply with the Directive ErP2015 (minimum efficiency requirements for fans within the EU), but actually exceed this standard. Most of our door air curtains are already equipped with fans using proven GreenTech EC technology from ebm-papst. Here the efficiency is > 90% under partial load operation. This is approx. 30-35% higher than for conventional AC fans. This does not just increase the efficiency, but also reduces the operating costs. Furthermore, EC fans have other advantages: including soft start-up (giving a longer lifetime), they are quieter and have blocking protection, overheating protection for the electronics, and a motor protection function – even at 60 Hz, etc.
