EDC Engine-Driven Compressor

EDC Engine-Driven Compressor

This unique engine-driven compressor (EDC) provides pressurized and conditioned cabin air under varying conditions for a specific class of aircraft. The complete EDC was developed and manufactured by Concepts NREC to offer significant advantages over main-engine bleed systems and has been used for several years as a retrofit upgrade for certain turboprop aircraft, enabling them to fly higher and carry a larger payload. The EDC consists of a single-stage centrifugal compressor driven through an integral gearbox and is equipped with variable inlet guide vanes that can modulate both pressure and flow at the same time. The EDC is currently used on turboprop aircraft by taking power off the accessory gearbox, but could also be driven by an electric or hydraulic motor.
