HDPE tanks for storage and dosing of liquid chemicals

What is a chemical storage tank?

Chemical compounds can be highly corrosive and damaging to storage tanks. That is why our rotomoulded tanks are manufactured with 100% virgin high-density polyethylene (HDPE), a material that offers exceptional resistance to corrosion.

Our chemical storage tanks also provide superior protection against ultraviolet (UV) rays, ensuring they stand the test of time in the face of harsh weather.

Tank volumes range from 20 to 20,000 L, depending on the model selected.

As they are made of polyethylene, their smooth walls facilitate the complete cleaning of liquids. Models with a full opening are available to make it even easier. 

Where are our chemical storage tanks used?

HDPE tanks storing liquid fertiliser on a farm

We design our chemical storage tanks to be used exclusively with liquids that have a density < 1.3 (depending on the model). Within these parameters, there is no need for structural reinforcement.

On request, our team may consider structural reinforcements for tanks that store liquids with a higher density.

We manufacture models for both liquid storage and dosing depending on the application to be carried out.

These characteristics make our tanks ideal for the following sectors:

  • agri-food industry
  • agriculture and livestock
  • chemical product management
  • liquid fertiliser dosing
