CNG Cylinders International Announces New Large Capacity Type III Cylinders

CNG Cylinders International has recently come out with a new product to fill a very important niche. They have just brought a Type III (aluminum wound with carbon fiber) cylinder that holds 25.5 GGE or 22.6 DGE.

This lightweight CNG tank is 22.5″  in diameter and 61″ in length (without valve and PRD.) It weighs in at a svelte 250 lbs empty.

CNG Cylinders International president Sigfried Rivalta announced that an even larger tank will be available within a couple of months. A 22.5″ x 80″. This tank will hold 34.2 GGE.

While liquified natural gas (LNG) is really the only way to get the volumes of fuel onboard necessary to keep an over the road truck supplied, there are plenty of shorter haul trucks which could still benefit from the cheaper and more user friendly CNG fueling model. These products will work very well for heavy trucks that make those shorter hauls. They could also be useful on medium to large sized agricultural equipment.

These tanks should compare very favorably in price with Lincoln and Quantum Type IV products.

The selection and mounting of CNG cylinders, or tanks, are among the most critical aspects of any CNG conversion. The array of options can be dizzying to a novice, and improper placement can significantly reduce the usefulness of a vehicle. Not only that, but improper tank installation can be dangerous. In this piece we will discuss the types of tanks and some mounting locations. I will also describe the planned installation on our F250 Powerstroke conversion.

There are four types of CNG cylinders: Types I, II, III, and IV. They are all going to be about the same size for a given gas volume. The main difference is composition and weight.

Type I tanks are made of steel. They are similar in construction to the cylinders used for welding gasses. They are the generally the cheapest option, but they are also the heaviest. A 10.9 gge (gasoline gallon equivalent) cylinder may come in a variety of lengths and diameters, but they’re all going to weigh about 320-350 lbs.
