BBR compressor

A favorite at fueling stations and in CNG transportation networks around the world, the BBR compressor is an ideal solution for reliable and energy-efficient CNG refueling and biomethane grid injection that makes no compromises on safety. The compressor is equipped with a zero-leakage pressured crankcase, direct drive and thoroughly referenced and tested technology

  1. 1
    Long-life mini lube design

    • Metered drop lubrication of cylinders through separate lubricator divider system reduces ring wear

    • Restricted piston speeds for longer ring and valve life

    • Synthetic rings also lessen friction and wear

  2. 2
    Efficient cooling

    • Air-cooled machines for trouble-free operation; avoids stoppages due to scaling, pump and cooling tower failures

    • Low discharge temperatures thanks to proper staging and large, efficient intercoolers

  3. 3
    Pressurized crankcase

    • Pressurized crankcase up to 35 bar(g) results in zero gas loss to atmosphere

    • Gas savings of up to 3 % versus unsealed compressors at first startup.

    • Compressor pays for itself within a few months of operation

  4. 4
    Smooth direct drive

    • No lateral loads on crankshaft and bearings, requiring less maintenance

    • No transmission losses unlike belt driven compressor ensures better operational efficiency

    • Reduced hassle of belt replacement and belt tensioning during operation

    • Avoids belt-related servicing; belts typically must be replaced every six months

    • Up to 1 800-rpm compressor running speed for direct coupling to gas or electric motor

  5. 5
    Control systems and other safety features

    • Comes with  Electrical & mechanical safeties to ensure safe & reliable operation

    • Control systems monitor critical points

    • Meets all major international codes and standards

    • Fully performance and safety tested with natural gas at designed capacity prior to installation

    • Extensive track record of safe operation extending over millions of hours of runtime

    • Optional independent third-party design verification of all pressure vessels, welding procedures and hydrostatic pressure tests

  6. 6
    Electric motor & soft starter technology

    • Reduces electrical shock loads resulting in longer operational life

    • Compressor will be unloaded in closed loop circuit in combination with blowdown vessel and ensure no-load start of compressor reducing starting currents requirements and increased the reliability

  7. 7
    Gauges Panel

    • Gauge panel provides information which helps to monitor compressor parameters during running conditions

    • BBV helps hassle free and quick calibration without venting out the gas from complete system

Customer benefits

  • Energy savings – Lower power costs and operating expenses pay off initial investment within a few months of operation
  • High reliability – Low piston speeds and interstate temperatures maintain internal parts
  • Safety – References all international standards and designed for zoned area application using explosion proof motors and suitable instruments
  • Pressurized crankcase – Up to 35 bar(g) crankcase pressure results in zero gas loss and offers gas savings of 2–6% versus unsealed compressors
