High Pressure Composite Cylinder :

  • Product :

    AutoDynamics is one of the pioneers in the area of design and manufacture of high pressure composite cylinder and cylinder modules for automotive and non automotive applications. These high pressure composite cylinders are use for storage of various fuels like LPG, CNG, Hydrogen, etc.

    Technology :

    The product is made of a liner base tank in plastic / steel or alternate material through a patented technology (Patent Appln. No. 2640/MUM/2011). This is layered with composite material of glass, carbon fibre, basalt or aramid fibres based on the end use application and the pressure requirements.

    Benefits :

    Compared to steel storage tanks, you get a weight savings of above 30%. Multiple storage tanks can be made into a module and can be made in different sizes to suit the end use.

    Applications :

    In Automotive, it is used for storage of CNG fuel. The CNG pressure goes to around 200 bar and is used in combination with petrol. In buses, a set of 4 cylinders is used as a module on the roof of the bus.

    Brief for High Pressure Cylinder :

    • Fuel : CNG / LPG
    • Cylinder for Passenger Cars, Light Commercial Vehicles and Buses
    • Flexible Cylinder Size

    Benefits for High Pressure Cylinder :

    • High Pressure CNG Storage Cylinder for 200bar
