Theese filling stations are specially designed for bus depots and there are two different variants of bus stations for buses; fast filling and slow filling.
Via bus ramps, up to several hundred buses can be connected at the same time, to be slowly refueled during the night and ready for operation the next morning. The fast-filling dispensers fill a bus tank with biogas within a few minutes, in a similar way to passenger car filling stations.
The slow-filling bus ramps have the advantage that they do not have to be monitored when refueling, since the process is handled automatically during the night. The driver does not have to wait for the bus to be filled and many buses can be refueled at the same time, when they are parked anyway.
Sometimes the need arises to fill a gas tank immediately and then a fast filling station is needed as a complement.
The most efficient bus depot uses both types of tank systems, which means that you are equipped for all situations and needs that arise.
