Dot Certified CNG Tanks
Safety Comes First when it comes to CNG Tanks! Compressed natural gas is very safe due to two important factors: the physical properties of natural gas itself and the CNG fuel system that is designed and built according to stringent quality standards. The physical properties of CNG make CNG safer to use than gasoline. For instance, CNG has a limited range of flammability compared to gasoline which can catch fire and burn easily. In order for CNG to burn, CNG needs between 5 to 15% of air in the fuel mixture or else the CNG will simply not be able to burn.
CNG Cylinders in the USA today are rated at 3,600 psi working pressure and have a life span from the date of manufacturer of 20 years. All CNG tanks and cylinders offered by CNG United are DOT certified and can also meet certification requirements in other Countries.
