CNG Filling Stations

At our CNG filling station, we provide facility that provides Compressed Natural Gas (CNG) fuel to vehicles that run on this alternative, cleaner-burning fuel source.
CNG Filling stations function similarly to conventional petrol or diesel stations but dispense natural gas that has been compressed to a high pressure (typically 200-250 kg/cm² or around 3,000-3,600 psi) to maximize on-board storage capacity in the vehicle's fuel tank.

Key Functions
Refueling Vehicles: The primary purpose is to offer a convenient and efficient way for public and commercial vehicles (cars, buses, trucks, etc.) to refuel with CNG.
Compression & Storage: Natural gas is delivered to the station (via pipeline or truck), treated (filtered and dried), and then compressed by powerful on-site compressors. It is then stored in high-pressure vessels or storage tanks before being dispensed.
Metering and Dispensing: The stored CNG is transferred to the vehicle's tank through a specialized dispenser, which accurately meters the amount of gas transferred and uses safety features like automatic shutoff.
  Metering is done in units of KGs and shutoff depends on the pumping presure.
Fill Speed: Our stations are fast-fill, where gas is stored in a cascade of tanks at high pressure. This allows for quick refueling, similar in time to filling a conventional liquid fuel vehicle (typically 2-5 minutes) for a full tank.

Advantages
Environmental: It is a cleaner-burning "green fuel" that produces significantly fewer harmful emissions (like carbon monoxide, nitrogen oxides, and particulate matter) compared to gasoline or diesel.
Economical: CNG is often more affordable than conventional liquid fuels, leading to lower operating costs for vehicle owners.
Safety: Methane (the main component of natural gas) is lighter than air, so in the event of a leak, it disperses quickly into the atmosphere, reducing the risk of fire or ground contamination.
Engine Longevity: The clean combustion of CNG results in less carbon residue and fewer by-products, which can extend the life of engine parts and reduce maintenance costs.

Components
Gas Meter Set Assembly (MSA): This is where the natural gas enters the station from the local utility pipeline. The MSA regulates the initial pressure and measures the amount of gas consumed by the station.
Gas Dryer/Dehydration Unit: Natural gas from pipelines often contains moisture. This component removes water vapor using desiccants to prevent damage to the equipment and vehicle engines, and to inhibit the formation of crystalline hydrates in the pipelines.
Filters: Filters are installed at various points in the system to remove impurities and solid particulates, which prevents maintenance issues and keeps the vehicle's fuel injector lines clear.
Compressor: This is the "workhorse" of the station. It takes the low-to-medium pressure natural gas and compresses it to a very high pressure (typically 200-250 bar or 3,000-3,600 psi) required for storage and vehicle fueling.
Storage Vessels/Cascades: The highly compressed gas is stored in a series of high-pressure tanks or cylinders, often arranged in "banks" (high, medium, and low pressure). This storage system ensures that gas is readily available for quick fueling and reduces the frequency of the compressor starting and stopping.
Priority/Sequence Control Panel: This intelligent system manages the flow of gas from the compressor to the different storage banks and then to the dispensers. It ensures efficient use of the stored gas and optimal fill times.
CNG Dispensers: These are the pumps that customers use to fill their vehicles. They are equipped with specialized hoses, nozzles (different sizes for light or heavy-duty vehicles), mass flow meters to accurately measure the gas dispensed, pressure gauges, and safety features like break-away couplings and emergency stop buttons.
Control Systems (PLC/Automatic Control System): A central control system, often using Programmable Logic Controllers (PLC), monitors and automates the entire process. It manages parameters, controls valve operations, and shuts down the system in the event of an emergency (e.g., fire detection or overpressure).
Safety and Ancillary Systems: This includes a range of safety equipment such as fire extinguishers, gas leak detectors and alarms, safety signage, grounding systems, and an emergency shutdown (ESD) system that can immediately isolate the station in a critical event

Services Offered
Note: Services offered at each station may change depending on it location, see our service matrix to know, filling station specific services.

While their primary function is to provide Compressed Natural Gas (CNG) for vehicles, we offer additional fuels and services.
pump for tire inflation (Free): Free air pump service for customers to check and adjust tire pressure (Both Air and Nitrogen)
Lubricants and engine oil (Paid): Lubricants and engine oil suitable and specific to CNG vehicles.
CNG kit repairs and services (Paid): During the day (9 AM to 6 PM) filling stations are provided with specialized mechanics, available for CNG kit repair and maintenance. These may include checking for leaks and fittings or engine diagnostics.
  During other timings (6 PM to 9 AM), these services are vailable only on the appointment basis and are not guranteed.
CNG cylinder testing (Paid): During the day (9 AM to 6 PM) filling stations perform periodic testing of CNG cylinders to ensure safety and compliance with regulations on request of the customer.
Car washing (Paid): Some selected urban filling stations, have an on-site car wash.
Restrooms (Free): Some filling stations, especially those on highways or operated by major companies, provide restroom facilities for customers.
Waiting areas (Free): Some filling stations offer a waiting area for customers, especially for those not located in Urban Areas.
  Few of the waiting areas are attached with mini convenient store and a small bakery, where selected food items, areated drinks, water (paid and free), soft drinks and tea/coffe are available on paid basis.
  In all waiting areas feeding room for feeding-mothers are availble.
