The most economical fuel for
buses and minibuses

Economic Success Factor
Steel composite (Type II), or full composite (Type IV) cylinders are recommended for the multi-cylinder fuel tank units for natural gas powered municipal buses or minibuses. Steel composite cylinders are available in a standard volume range of 60l - 165l. A combination of different sized cylinders can be used to achieve the required total volume.

The following example shows a possible unit configuration:

Tank unit with 7 cylinders
Total volume 1.055 l
5 cylinders each of 165 l plus
2 cylinders each of 115 l
The cylinders only weigh some 653 kg (without frame).

Such units are used for municipal buses and are mounted under a hood on the roof.

Due to the low weight, tank units of full composite cylinders are suited for larger storage volumes and thus longer ranges. Full composite tank units consist, according to service requirements, of 5 to 9 cylinders each with 190 l capacity, thus the total volume of these units is between 950 l to 1.710 l, whereby the weight of a 190 l cylinder is only about 52 kg.

Both steel composite and full composite cylinders are equipped with melting fuses at each end, thus offering double safety should the fuses need to be activated. These cylinders have a service pressure of 200 bar.

MCS can, of course, supply ready to install tank units including frame and piping along with all high pressure accessories.
