CNG installation

What is CNG? 

Compressed Natural Gas (CNG) is stored by a compressor compresses gas to a higher pressure (approx. 250 bar(g)). The gas then takes up less space and can be stored in larger quantities. The filling of motor vehicles is also done under this high pressure. This means that a considerable amount of gas can be refuelled in a short time.

CNG installation inspection

A CNG installation must be legally approved (in accordance with the Environmental Management Act > PGS 25 and the Pressure Equipment Commodities Act Decree). ECH carries out various inspections: conformity assessment, inspection before commissioning and periodic inspections. Our specialist can also perform a test based on the regulations of the PGS 25. You can also have an explosion safety document prepared by a certified senior safety expert.

What does the inspection entail?

• ATEX zoning;
• Safety break coupling hose;
• Both internal and external condition;
• Earthing report;
• Emergency stop operation;
• Security of the installation. 

When is a periodic inspection needed?

After the statutory period (four years) has expired, the installations needs to be inspected again. Both the inspection before commissioning and the periodic inspection can be combined with the inspection according to the PGS 25. 

The inspectors of ECH are aware of technical details and applicable regulations concerning the Environmental Management Act, External Safety and the Publication Series on Hazardous Substances (PGS). ECH has been designated by the Ministry of Social Affairs and Employment as a Certification and Inspection Body (NL-CBI). ECH is also accredited by the Dutch Accreditation Council based on the ISO-IEC 17020 (RvA I128) standard.
