Technical performance and chemical compatibility

Texte Gauche
  • Chemical resistance: the chemical inertness of HDPE (high density polyethylene) and PP (polypropylene) guarantees the reliable storage of corrosive and dangerous chemicals. Following rinsing, a vessel may, for example, store caustic soda followed by hydrochloric acid. They are extremely versatile.

  • Resistance to UV.

  • Mechanical resistance: the roll-extrusion process can produce linings with variable thickness along the vertical plane. Thicknesses are specified according to the products being stored. The lining thus produced is both free of internal stress, mechanically homogeneous, isotropic and balanced (no tension-compression). The thickness of the wall can reach up to 120 mm.

  • Increased safety due to an optional double envelope: the very design of the retention tank guarantees 100% reliable storage. No leakage possible.

Texte Droite
  • Versatility of tanks: each tank can be given a different function through the use of peripheral equipment such as service access and walkways, gas scrubbers, heaters... Many types of equipment and accessories are available, allowing customers to create a complete storage environment.

  • Guaranteed traceability of materials used.

  • Significant thermal insulation.

  • Recyclability of material: EELIX tanks are 100% recyclable, even after 30 years of use. The materials used are perfectly suited to a circular economy

Configuring your tank

Materials selection

According to product being stored (see compatibility table) and storage temperature.

Opposite: HDPE (-45° to +45°C – black) and PP (-10° to +90°C – beige).

Series selection

The tanks are compliant with EN 12573-2 based on the nature of the product being stored with respect to concentration, density and corrosion factor (A2K).

  • CHEMICAL series: density ≤ 1.4
  • HEAVY series: density ≥ 1.4
  • OXIDISING series: bleach and hydrogen peroxide
  • SPECIAL series: concentrated sulfuric acid or nitric acid

Retention

With retention for increased safety or without retention.

Selection of dimension

  • From 2,000 L to 100,000 L
  • 8 internal diameters from Ø 1,200 mm to 3,400 mm
  • Cylindrical heights are indicative; any intermediate height can be produced by request.
  • Download the dimension table.

Selection of accessories

  • Main accessories
    • Service access and walkways
    • Gas scrubbers

    • Heaters

    • Agitators

       

  • Additional accessories: manholes, taps, filling tubes, belts and straps, safety bungs, rain clip, valves, level measurement, mounting brackets
