Liquid Fertiliser System. Stronger. Safer.
Freedom Tanks are the number one supplier and installer of tanks for the Flexi-N system. And little wonder. It was Freedom Tanks’ design and engineering expertise that helped bring the Flexi-N system from concept to reality. Flexi-N fertiliser has a density 1.3 times greater than water and applies extreme pressure to tanks. For added safety, Freedom Tanks designed and proved a specialised range of products to withstand densities 1.5 times greater than water.

Seamless one-piece design for extra strength.
