The BAUER GRU® MB5 is the perfect match-up to the GRU biogas recovery compressor system since the GRU MB5 utilizes the outlet pressure generated by 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: 73 - 363 psig ( 5 - 25 bar)
  • Horsepower range: 50-350 HP (37-260 kw)
  • Biogas Flow Rate: 321 - 2300 scfm (545.4 - 3907.6  nm3/hr)
  • Final pressure: 300-1100 PSIG (21 - 76 BAR)

STANDARD SCOPE OF SUPPLY

  • Heavy-duty rotary screw booster compressor at the heart of the system
  • Variable speed control of compressor to modulate the flow of biogas based on the incoming supply of gas (VF drive located
  • remote from skid as defined by Class 1, Div 2 code requirements per NEC NFPA70)
  • Heavy-duty TEFC electric motor
  • Stainless steel construction of piping and major P&ID components
  • PLC control of all major system components
  • BAUER CONNECT® remote telemetry IoT with Modbus TCP/IP or Profinet connection capability
  • Fully integrated system built on a heavy-duty steel skid designed for plug and play installation
