Ventilation system designers can combine a VLT® HVAC Drive with the most efficient fan and permanent magnet motor, using Danfoss Drives’ EC+ concept. The combination of components allows users to achieve the full potential of a highly efficient fan.
overall system efficiency
To achieve the highest performance and system efficiency when building an HVAC system, the individual components – drive, motor, and fan – need to be flexible and broadly compatible with each other.
For instance, if a high-efficiency motor that is only compatible with lower efficiency fans is selected, the overall system efficiency would suffer and would not reflect the highest performance – and investment – in the individual components. The EC+ concept allows the ventilation system designers to combine a VLT® HVAC Drive with the most efficient fan and high-efficiency permanent magnet or synchronous reluctance motor for best energy efficiency.
Advantages
The key to the EC+ is intelligent interaction of the system components. Only the optimal interaction of the system components – fan, motor, electronics, diffuser – makes the full potential of a highly efficient fan realizable.
Advantages of the EC+ concept:
- Free choice of motor technology: PM, asynchronous, or synchronous reluctance with the same AC drive
- Device installation and operation remain unchanged
- Manufacturer independence in the choice of all components
- Superior system efficiency thanks to a combination of individual components with optimum efficiency
- Retrofitting of existing systems is possible
- Wide range of rated powers for standard, PM, and synchronous reluctance motors
