Fan manufacturer ebm‑papst shows how the future can be shaped in harmony with the values of our time. The company wants to use its core competencies in aerodynamics, electric motors and electronics to not only support megatrends such as climate neutrality and digitalization, but to actively drive them forward. It is from this perspective that the product range and expertise within the company are being further developed.

ebm‑papst is expanding its product portfolio to include turbo compressors for different air and gas mixtures. These turbo compressors are used in heat pumps, self-contained drinking water systems and gas supply systems for fuel cells, for example. All components, from the drive motor to the compressor impeller and the newly developed oil-free high-speed bearings, are coordinated to suit the specific application.

High performance in a small installation space
Designed as a platform solution, individual compressors with outputs from 1 to 45 kW can be quickly assembled and different refrigerants, air and other gas mixtures can be compressed without oil. Thanks to their high speeds, the turbo compressors are very compact compared to conventional solutions, operate vibration-free and do not require any lubricating oil. This is of interest wherever gas purity is required. The gas bearing, which is not subject to contact or friction during operation, not only achieves a long service life but also has impressively low noise levels.

Tailor-made compressor platform
The new compressor platform enables a wide range of different applications to be operated economically. By combining different impeller sizes and blade geometries, it enables optimum aerodynamic adaptation to the application. This means that, depending on requirements, the impellers can be matched to the required mass flow or pressure ratio and the working gases used, such as air or R290.

First prototypes already in use
The P1 (1 kW) and P2 (2.8 kW) platforms are already available as prototypes and are also in use in customer applications. Series production processes were already considered in the concept phase, which will contribute to a competitive cost structure in future series production. With the help of the technical center currently under construction at the main site in Mulfingen, the first small series will start as early as the beginning of 2024. Series production, which is planned from 2026, is aiming for volumes significantly higher than one hundred thousand units per year and platform size.
