  • Percentage of Fiberglass from 55 to 60%, for a high mechanical resistance.
  • High resistance to external corrosive agents.
  • Easy cleaning, high durability, maintenance is not necessary and easy to repair in the event of a break.
  • GRP is resistant to both high and low temperatures, avoiding condensation. It is also a good electrical insulator.
  • The calculation and design is done in accordance to the product to be contained, the working temperature and the concentration of it.
  • Lightweight and easy transportable equipment.
  • Pumped and conical bottoms.
