​Fast-Fill Compressed Natural Gas Dispenser

​Fast-Fill Compressed Natural Gas Dispenser - Parker Velcon - Process controlsTo reduce their environmental footprint and decrease fuel costs, many fleet operators are turning to natural gas (NG) as an alternative to gasoline or diesel. Natural gas provides comparable amounts of power and acceleration while producing lower levels of emissions and particulates, often at a significantly lower cost. A heavy duty vehicle powered by natural gas, such as a refuse truck or passenger bus, produces up to 15% fewer emissions of greenhouse gases and harmful particulates than a standard diesel model.

Compressed natural gas (CNG) challenges

  • Developing CNG refueling infrastructure
  • Natural gas vehicles can cost up to 40% more than equivalent gas vehicles
  • Longer refueling time
  • Greater weight of fuel tank
  • Currently only on a limited number of vehicles

CNG advantages

  • Natural gas is plentiful in North America and relatively inexpensive, particularly in light of the fact that gasoline and diesel fuel have jumped in price by more than 30% since winter of 2015
  • NG produces 30% fewer greenhouse gas emissions than gas or diesel
  • NG is safer, with a low chance of flammability
  • Supply of NG is expected to exceed demand, keeping prices depressed
  • Government push to alternative fuels through environmental regulations, tax credits, and incentives
  • Using existing natural gas lines makes vehicle refueling at home easy
  • NG engine availability is increasing
  • NG vehicles offer longer vehicle life with less long-term expense for the consumer

Dispenser makes a natural gas fillup seamless

When it comes to filling the tank, the transition to a vehicle powered by natural gas feels seamless to a driver refueling with a Parker Compressed Natural Gas (CNG) dispenser. The unit is capable of quickly refilling the empty fuel tank of a small passenger car or heavy duty truck, refuse vehicle or passenger bus. It displays traditional metrics such as the fuel quantity and cost, in addition to natural gas specific measures of flow rate and pressure, offering a familiar and convenient user experience. Web enabled communication allows for cloud-based monitoring, fleet management and predictive maintenance.

Designed with safety as a top priority, the Parker CNG dispenser uses a series of protective sensors, breakaway couplings and hose, 25 disconnects to eliminate the risk of mechanical or user malfunctions. The system is held to the highest standard of quality to prevent leakage, minimize downtime and provide consistent and reliable service. With Parker Tracking System (PTS), we can track calibration cycles, spares and periodic maintenance, making it a superior ownership experience.
