Celeroton AG

The Swiss high-tech company Celeroton AG is the leading manufacturer of ultra-high-speed electrical drive systems and turbo compressors with speeds up to 1 million rpm.

Faster, smaller, lighter and more efficient: Celeroton‘s turbo compressors, converters and permanent-magnet motors are designed for the highest energy efficiency at the lowest volume and weight. Their innovation lies in the interdisciplinary know-how in the areas of aerodynamics, gas and magnetic bearings, mechanics, electromagnetics, electronics, control systems and software that allows for outstanding solutions in terms of compact size, efficiency and control performance.

Application areas of the turbo compressors include air supply systems for fuel cells, air conditioning and heat pumps, high-tech blowers, respirators and oxygen concentrators, and decentralized pneumatics. The motors and converters are applied in the medical and dental industry, in spindles for micromachining, and to drive rotating mirrors and prisms in optical systems, lasers and scanners.

The company was founded in 2008 as a spin-off company of the Swiss Federal Institute of Technology in Zurich (ETHZ).

Contribution to INN-BALANCE:

The specific goal and objective of Celeroton in the INNBALANCE project is the design, realisation and testing of a turbo compressor with gas bearings for the air supply of the fuel cell, based on its high speed motors and radial turbo compressor technology with lowest ratio of volume and weight versus pressure and mass flow, and with thermodynamic and electromagnetic optimization for highest total efficiency. The targeted efficiency is 85% with a power density of 0.5kW/kg and a power range of 10-12 kW. In addition, Celeroton will design and realise a customised electronics to drive the turbo compressor.
