PBS Turboexpanders are primarily designed for the expansion of gases such as hydrogen, helium, nitrogen, argon, air, etc., in a gas liquefier.

  • Easy regulation
  • High efficiency
  • Rotor placement on gas-dynamic bearings
  • Long-term and trouble-free operation
The extracted gas heat energy is transformed into the mechanical energy of the shaft in the turbine through the turbine wheel. This mechanical energy is then transformed into thermal energy via an integrated turbine brake, which is then drained out of the turbine by means of a coolant.

PBS expansion turbines have a unified design that makes it possible to quickly respond to customer requirements for various input and output parameters of the expanding gas.

The main advantage of PBS expansion turbines is the very easy and precise speed control with the turbine brake, as well as their long-term trouble-free and maintenance-free operation thanks to the placement of the rotor on gas-dynamic bearings.
