About CNG GC Filling Stations

CNG (compressed natural gas) filling stations are compact, efficient and highly reliable facilities designed for filling up passenger vehicles, utility vehicles and buses driven by natural gas and bio-methane.

Description of the Filling Technology

First, the natural gas is passed through a drying appliance where moisture is removed with a molecular screen and purified through filtration equipment. Then the gas is compressed to 25 to 30 MPa according to the type of compressor. Under this pressure gas is delivered to supply bottles or directly into the filling equipment (stand). Using a filling hose the gas may be delivered to the pressure tank of a vehicle. The filling process automatically stops after reaching a pressure of 20 to 21 MPa. The filling hose is then disconnected from the vehicle’s tank and all is ready for the next filling.

All CNG GC filling stations comply with regulation TPG 304 02. The operator of the filling station must be certified by an organization of the state professional supervision, Technical Inspection, for filling pressurized gas bottles (including pressure stations) according to Regulation of the Czech Labour Safety Institute and Czech Mining Institute No. 21/1979 Coll., as amended.

Corporate Filling Stations

CNG GC 20-55

The GC 20 – 55 filling station series is suitable for premises of medium-sized and large companies with a number of utility and passenger vehicles from approx. 10 to 30.

CNG Type Station – Structure

The high-tech container is built as a self-contained structure with a steel frame reinforced by porous concrete. The container has a single space which contains the distribution mechanism. The container is equipped with a roof in the filling area and a control-touch panel for filling vehicles.

To fill vehicles, a filling hose equipped with an NGV1 end piece leads straight from the container of the filling station. For maximum safety, the area with the technology is monitored by a gas leak detector and the entire technology meets all the requirements for a safe and ecological operation. The filling station may be connected to a service centre for the option of immediate diagnostics of the technology.

Public Filling Stations

CNG GC 85-150

CNG Type Station – Structure

The high-tech container is designed as a self-contained steel structure with heat and noise insulation. The standard colour is selected by the customer. The container is divided into a mechanical-technological part and a part for the electrical switchboard, which is gas-proof and separated. The mechanical-technological part includes two entrances to maximize accessibility. There is another entrance leading to the switchboard. The container is installed on prepared foundation strips and it can be structurally prepared with increased fire resistance to 45 minutes, or for installation in seismologically unfavourable areas. The container includes all the technology of the CNG filling station.

For maximum safety, the area with the technology is monitored with a gas leak detector with acoustic signalization. The entire technology corresponds with the strictest requirements for a safe and ecological operation.

The control panel with a touch display is installed on the switchboard and it allows monitoring of all the important parameters, including the status and failure history. The filling station is commonly connected to a service centre for immediate diagnostics of the technology.
