After completion of the development of an impulse-type, axial-flow expander, the design of a reaction-type, radial-expander turbine was undertaken. Particular emphasis was placed on turbine efficiency and reliability. Angularly adjustable nozzles control the flow. Two sizes were developed covering a range from 5 to 150 cfm exhaust volume Peak efficiencies reached are as high as 92 percent. Consequently 87 percent are being guaranteed. Load absorbers are radial-flow compressors. Compressor efficiencies as high as 89 percent have been measured. A unique cartridge design permits exchange of rotor, bearing and seals in a few hours.
