Turboexpanders are needed for cooling gas through its expansion. When in turboexpander the energy of compressed gas is converted into mechanical rotational energy of the turbine wheel.

GazSurf can offer turboexpanders of various configurations: 

  • expander-compressors allow utilizing the energy obtained from gas expansion in the expander section to rotate the compressor shaft.
  • expander-generators convert mechanical energy into electricity.
  • hydrodynamic brake-equipped expanders compensate for the energy obtained from gas expansion by rotating a brake wheel in liquid.
