CNG STATION SETUP & SAFETY

The local gas utility supplies a meter set assembly (MSA) to regulate and measure the amount of gas being used. It is important to work closely with the utility to determine the pressures and flow rates that are available at each site, and to determine if any service upgrades will be needed.

Inlet gas with high moisture content will require “drying” in order to make it suitable for fueling vehicles. The dryer removes residual water vapor with desiccants that are regenerated for reuse.

Compressors are the workhorses of the CNG station and must withstand the rigors of heavy-duty daily use over many years. Trillium utilizes CNG compressors with an unmatched record of service, long life and superior factory support.

Compressors keep on-site storage vessels full allowing for short fill times which are usually between 3-5 minutes, depending on the amount of storage at a station and the requirements of the vehicle.

CNG can be dispensed through a fast-fill or time-fill system. Fast fill systems provide fill times similar to gasoline and diesel fuel dispensing, and often include fuel management and credit card systems for payment. Time fill dispensers may take hours to provide a “full” fill.

Trillium employs various hose and dispenser features to ensure safety while fueling. Breakaway devices at each dispenser hose will cut off the gas supply if a customer were to drive off with a hose still attached. Gas flow will also be interrupted if the dispenser is damaged through impact.

Trillium’s proprietary and proven smart controls optimize fueling, balance equipment loads and minimize the number of compressor starts to decrease wear on equipment.

System controls monitor equipment performance and automatically shut down a station in the event of unsafe fueling conditions. If needed, Emergency Shutdown (ESD) buttons are located in several places on-site and will cause a station to shut down entirely when pushed.
