6,200 Gallon / 28,000L Dunder Tank

SKU PTRNDU6200 Categories , ,

Dunder has a higher specific gravity score than water. Therefore Dunder storage tanks have to be specifically made to securely store Dunder. Nu-Tank Dunder storage tanks are made to store liquids with a specific gravity of up to 1.2. This is more then what is required to safely store your Dunder.


  • Specific Gravity of 1.2
  • Fully self supporting roof (no internal poles or frames)
  • Manufactured from proven Australian standard materials (tested in the field for over 25 years)
  • Manufactured in computerised ovens (not open flame)
  • Ribbed side walls (extra strength)
  • Thicker walls at base (supports pressure)
  • Poly fused & welded fittings (stops fitting split)



*Inclusions may change without notice, check with sales prior to ordering
¹Standard sizing of Butterfly Valve and Stub Flange 3″, 4″ and 6″, other sizes available on request

At Nu-Tank we don’t take short cuts, not with the materials we use in the manufacture of our tanks, nor in the manufacturing process securing your liquid investment.


Our Polyethylene Water Tanks pass what we call the 6 Point checklist (a checklist you should use before buying any water tank). They come with a fully self supported roof with absolutely no internal poles or frames. Thicker walls at the base of the tank, where the greatest pressure is. Ribbed side walls for extra strength (just like the human body). Poly fused and welded fittings, making the fitting one single piece with the tank, leaving nowhere for fitting split to occur. Manufactured in computerised ovens for an even baking process and most importantly of all made using proven materials that are food grade, BPA and heavy metal free.

A Nu-Tank is strong and reliable just the way they should be.

* BPA and Heavy Metal Free pertains to the polyethylene components only.
