In addition to the required air flow, energy efficiency and noise emissions are crucial for fans in ventilation and air conditioning systems. To achieve design improvements, the overall fan system comprising impeller, motor, housing and control electronics must be optimised.
Using its expertise in aerodynamics, motor technology and electronics, ebm-papst has developed a new series of EC axial fans with diameters from 400 to 910 mm. With single- and three-phase designs, these fans cover the power range from 250 W to 1,3 kW with noise emissions that are up to 3 dB(A) lower than previously – with increased air performance.
At the foundation of the new generation of fans are two new EC motors that achieve a higher power density thanks to their improved heat dissipation and use of the latest materials. The new generation’s modularity in terms of motors and electronics allows selection of the best combination for a given operating point and power supply requirement. The high efficiency of the GreenTech EC fans is an added benefit.
The air performance can be regulated as needed via the 0 – 10 V / PWM interface or the serial RS-485 MODBUS interface. The interface also features a 10 V output for connecting sensors (e.g. pressure or temperature sensors) and a floating alarm relay output as standard. An optional module is available with an expanded interface with the familiar functionality from ebm-papst’s EC technology such as a PID controller, a 20 V output or digital inputs for extended parameter sets.
These fans satisfy the requirements for the IP54 protection rating and the relevant international standards for industrial and household use (e.g. for heat pumps according to the 60335-1 household standard). Typical applications are any air-cooled heat exchangers such as condensers or chillers. This new generation exceeds the ErP 2015 environmental design requirements.
