FillSafe Fuelling Hoses

NanoSUN’s advanced FillSafe Fuelling Hoses are engineered to safely and easily refuel hydrogen tanks from hydrogen cylinders.

The hoses use a simple decant method to channel hydrogen into customers tanks. The fill efficiency is dependent on the pressure in the filling cylinder.

The FillSafe Hoses are capable of refuelling up to a maximum working pressure of 300 bar. Lower pressure variations are also available. 

Low cost
