Sapphire Technologies Overview

FreeSpin In-Line turboexpander (FIT)

  1. Conversion of wasted pressure energy into clean electric power
  2. High-pressure gas enters FIT
  3. Kinetic energy is converted to rotational energy in the wheel
  4. The wheel spins a PM generator creating voltage in a stator
  5. Current is transmitted from the stator to a variable speed drive (VSD) via power cabling
  • Active magnetic bearings levitate rotor during operation
    • No friction
    • Low life cycle cost with 20-yr design life
  • Expanded (cooled) gas exits wheel and flows-through generator section
    • No additional cooling required
  • Hermetically sealed, no-leak housing
    • Flange-connected into pipeline
    • No penetrations for lubrication or cooling
