Biogas Compressor Solutions



The BAUER GRU™ HP Gas Booster utilizes rotary screw compressor technology and has been specifically designed for biomethane injection into the pipeline grid for applications where higher pressures (up to 600 PSIG) are required. The BAUER GRU™ HP rotary screw booster is also suitable for large gas turbine power generators that require higher gas inlet injection pressures.

All BAUER GRU™ Booster units are equipped with variable frequency speed control which allows the compressor to adjust to the incoming flow of gas. Utilizing a rotary screw booster compressor is advantageous over reciprocating piston compressors due to the higher reliability and lower cost of ownership of rotary screw compressors especially in continuous duty applications.



The BAUER GRU™ HP is the perfect match-up to the GRU™ biogas recovery compressor system since the GRU™ HP utilizes the outlet pressure generated by the GRU™ Biogas Recovery Compressor to boost the pressure of the biogas up to pipeline pressure or pressure required by the gas turbine generator system.

  • Inlet pressure range: 80-230 PSIG (5.5-15.8 BAR)
  • Horsepower range: 150-350 HP (112-260 kW)
  • Biogas Flow Rate: 1350-3300 SCFM (2293-5606 M3/HR)
  • Final pressure: 400-600 PSIG (27.5-41.3 BAR)
