5.1 EC- Technik
EC technology is based on the optimum utilisation of the motors which are controlled by the integrated electro-
nic. The electronic avoids slippage losses and ensures that the motor is constantly adjusted to optimal operation. In
addition, the control electronics ensure that the proportion of effectively used energy is much higher compared to AC
motors. EC fans stand out thanks to their effi cient use of energy and their outstanding adjustability. The speed of the
fans can be freely adjusted to meet ventilation requirements. The fans also operate very effi ciently. This means that
they use far less energy than AC drives, whilst providing the same air performance. Furthermore, EC motors can save
energy both in partial and full-load operation. They lose less of their effi ciency in partial-load operation than asyn-
chronous motors of the same power.
5.2 Characteristics
The MUB CAV/VAV with the integrated controller offers you the possibility for a constant airflow (factory setting) or
constant pressure ventilation. The following operating modes are possible to adjust with the controller (for further
information for adjustment of the controller, please take the attached operating manual of the controller):
•
CAV --> Constant Air Volume
•
VAV --> Variable Air Volume
•
