Monopropellant Hydrazine Propellant Tanks

Portfolio of space qualified hydrazine propellant tanks for operation in blow-down or pressure regulated modes.


Selection of titanium hydrazine tanks ranging from 58 litre to 177 litre capacity. The 58 litre model is a bladder tank, the others being surface tension tanks.

 

A brief overview is available for both types of hydrazine tank, together with an insight into our propellant tank manufacturing facilities.
