Fuel Filtration
Fuel filter construction kit Blue.maxx
The flexible Fuel filter concept also for alternative fuels
Due to the complex technology of today's combustion engines, the integration of a modern fuel filter system is essential. This is because a large number of very fine particles as well as water droplets must be reliably filtrated. In the future, alternative fuels and their blends will be increasingly used in commercial vehicles and off-highway applications, alongside alternative concepts such as electric drives, hydrogen engines and fuel cells.
Hengst has developed special test methods to optimally adapt the Fuel filter system to alternative fuels.
One example of the products developed in this way is the innovative Blue.maxx fuel filter system. It is based on Hengst's comprehensive development know-how. The system is suitable for all fuels that are used today and will be used worldwide in the future - whether fossil, biogenic or synthetic. In order to meet the diverse requirements of modern engine technology in the commercial vehicle and off-highway sector, Hengst has designed the fuel filter system on a modular basis. It can be quickly and easily adapted to different applications as an original equipment or retrofit solution.
