Open Top Tanks

Open-top tanks are typically process-oriented tanks that are used for blending or containment. These tanks make an ideal solution for applications that require mixing or blending as they provide ease of access to dose bulk dry materials.

They are also used extensively for aquaculture due to smooth inside surfaces and the AS/NZS:4020 compliant polyethylene being safe and non-toxic to aquatic life.

  • Capacities from 450 to 25000 litres
  • Smooth inside surfaces prevent damage to contents
  • Full drainage sumps available.
