Oxnard, Calif.-based CNG Cylinders International is promoting the industry’s largest Type III compressed natural gas fuel cylinders at Booth 3762.

CNGci’s carbon fiber on aluminum tanks are available in diameters of up to 25 inches. The 100-inch-long version of the new 25-inch diameter tank has an internal volume of 631 liters, equating to 55 diesel gallon equivalents.

CNGci makes the point that because its liners are aluminum, they better conduct the heat generated when fast-filling, allowing more gas to be put in the cylinder before maximum pressure is reached.

The difference can be as much as 37% more actual fuel in the tank in a fast-fill situation.

CNGci manufactures the large forged seamless AL6061 aluminum liners for its CNG fuel cylinders in Oxnard, and does its own filament winding there as well.

In addition to the Type III tanks, CNGci distributes Type I steel cylinders manufactured by Vitkovice in the Czech Republic, and Type II wire mesh-wound tanks from Virginia’s WireTough Cylinders, Inc.
