Storage of certain concentrated chemicals can be extremely challenging, because of concerns such as chemical attack, high specific gravity, UV attack and oxidation.  If you store your chemicals in our tanks, these become non-issues!  Our tanks are extremely well-suited to concentrated chemicals such as:

  • Sulfuric Acid up to 98%
  • Sodium Hypochlorite (Bleach) up to 19%
  • Hydrochloric Acid up to 36%
  • Nitric
  • Ferric Sulfate
  • Hydrogen Peroxide
  • Variety of others

Note: Level of concentration is dependent on storage temperature
