How A CNG Station Works



  • 1. Gas Meter
    Your local gas utility will supply a meter for the CNG station to measure the amount of gas you use. It is important to work closely with the utility to determine the pressures and flow rates that are available at your site, and if any service upgrades will be needed.
  • 2. Gas Dryer
    In the dryer, gas flows through filters and a desiccant bed to remove moisture and contaminants. Only clean, dry gas flows to the compressors.
  • 3. CNG Compressors
    The compressors are the workhorses of every CNG station and they must withstand the rigors of heavy-duty daily use over many years. To meet this demand, Trillium installs reliable Ariel compressors, as they have an unmatched record of service, long life, and superior factory support. Compressors are housed in sound-attenuated enclosures that minimize noise.
  • 4. High Pressure Storage
    From the compressors, Trillium's advanced control system will manage the flow of gas and determine whether to send it to storage or to bypass storage sending the gas directly to the dispensers.
  • 5. CNG Fuel Dispenser
    Fuel can be dispensed through a Fast-Fill or Time-Fill system. Fast fill systems provide fill times that are similar to gasoline and diesel fuel dispensing, and often include fuel management and credit card payment systems. Time-fill systems refuel vehicles overnight while they are not in service.
