The experts at Cemo have used a mix of materials to develop the DT Mobil PRO hybrid, an extremely robust and environmentally friendly mobile refueling solution for diesel. The tank has a capacity of 980 liters. With three millimetre steel walls, the outer skin is very stable and offers excellent mechanical protection for the contents.
The PE inner tank used, on the other hand, significantly reduces the weight, is insensitive to corrosion and produces significantly lessCO2 during production compared to a steel inner tank. A hybrid tank made of steel and plastic constructed in this way therefore saves energy and raw materials during production and subsequent transportation. The PE inserts do not have to be replaced after five years, but only after eight years. During the many years of use, diesel pest often develops, also encouraged by the bio content in the fuel. The bacteria and fungi form sludge or slime that clogs the fuel filter. Steel tanks can then only be cleaned to a limited extent and a permanent use of biocides is then necessary. The replaced PE insert, on the other hand, is absolutely clean and the serviced tank is as good as new.
Some figures: A hybrid filling station with a PE inner tank saves 32.2 percentCO2 during production (in figures 320 kgCO2), i.e. around a third. The hybrid tank also weighs significantly less: the steel outer shell weighs 257 kg, but the PE insert weighs only 60 kg, whereas a steel insert weighs 200 kg.
The total weight of the hybrid tank is therefore approx. 27 percent less than the pure steel version. Calculated over eight years with an average of 5000 km per year, transportation in the lighter PE version saves around 26.6 percent emissions or 935 kg ofCO2. That is the equivalent of around 355.5 liters of diesel.
