Rotating machines

Electric compressors

Electrically driven turbochargers and compressors offer versatile and hermetically sealed operation across a broad temperature spectrum, ranging from cryogenic to high-temperature applications. They demonstrate exceptional performance as standalone systems or when seamlessly integrated into vacuum or high-pressure machines, owing to their ultra-low friction and high reliability.

Air supply for fuel cell systems

Compressors for fuel cells are crucial in ensuring the optimal performance of fuel cell systems. These electrically powered turbochargers and compressors play a vital role in delivering compressed air to the fuel cell stack, where oxygen is extracted from the incoming air for the cathode reaction. The quantity and purity of the air supplied are paramount for the efficiency and reliability of fuel cell systems, as contaminants can be detrimental to the performance of fuel cells. Factors like compressor weight, response time, and operational noise levels are carefully considered to ensure seamless integration into fuel cell systems for transportation applications.
