Bipropellant Tanks

Portfolio of space qualified bipropellant tanks for satellite and spacecraft propulsion systems.


Selection of titanium surface tension propellant tanks ranging from 198 litres to 1450 litres. The capacity of parallel section tanks may be adapted by varying the length of the cylindrical section.

 

A brief overview is available for surface tension tanks, together with an insight into our propellant tank manufacturing facilities.
