In the turbo expanders ЕСО family, the shaft power is absorbed by oil brake with fixed power/speed curves.
Low flow, low pressure expanders are mostly used for relatively small N2/O2 generators. The turbo expander ЕСО use reliable forced feed oil lubricated bearings and brake (much more reliable than air brake with air bearings).
These expanders can accept up to 70 % of oxygen in the process gas.
