Sprinting Cheetah!

Our newest design highlight in 2023 – an integral gear unit with maximized compactness and minimized weight. Transmitted power 2 x 1200 kW @ 65000 rpm compressor speed.

Impeller thrust forces are transferred to the low-speed shaft bearings via solid thrust collars.

A planetary gear stage with flexible pins reduces the bull gear diameter by 70%. The gear unit runs successfully since September 2023 in a prototype power-to-gas energy storage system in Northern Europe.
