Each Gigabox® has an “MX 400” compressor, which includes a 350 kw gas engine that provides 2,800 m3 flow per hour. Aside from the compressor, the ColdBox® and the storage battery of 3,000 liters optimize the buses fueling capacity. While the Coldbox® cools the CNG before sending it to the vehicle, thus allowing the supply of a larger amount of gas to the cutting pressure, the storage battery absorbs demand peaks.
Among the refueled vehicles, there are thirty articulated buses of 18 meters long, 30,000 kg weight and with capacity for 160 passengers. These buses fill up 100 m3 of CNG allowing the completion, without intermediate refills, of the trip along 13 stations that have a daily ridership of up to 120,000 users.
