Electric auxiliary units


Due to the synergy of our e-mobility and our motor division, we created an application orientated product series of electric auxiliary units for battery powered electric utility vehicles and electric busses, the compAUX-series. During the development, we focused on optimizing these products regarding noise, energy efficiency, size, weight and costs. This way we managed to set a new standard in economic efficiency, production and technology.

Thanks to the application orientated development, our auxiliary units, which are especially designed for battery powered electric vehicles using inverter driven PM synchronous motors, fulfil a variety of customer wishes. Compared to other available products on the market, which are mostly powered by asynchronous motors, our units are up to 3-times smaller, 6-times lighter and are more energy efficient.

It doesn’t matter, if our auxiliaries are installed in an electric bus or electric truck, using our electric air compressors or electric power steering pump, you will not only save valuable space and weight but also money due to our optional individual demand based control and maintenance concept.

If we did raise your interest, we would be more than happy to give you more information about the compAUX-series air- or watercooled compressors and power steering pumps. So please don’t hesitate to contact us and to benefit from our expertise and products for the future electric transportation sector.

But we’re not standing still and are continuously improving and extending our product portfolio. Currently we’re developing a new, stronger electric air compressor, based on the same compressor screw technology that we use for our current products. It will provide a flowrate of 450 l/min at 12-13 bar to be used with electric busses and trucks that have a higher than standard air demand. Furthermore, were designing low voltage 24-48 V watercooled motors to be used in conjunction with our current low noise power steering pump and air compressor.
