Industrial Tanks

The know-how and the experience allow Pisano Engineering to position itself as an important player in the thermodynamic and mechanical design up to the realization of shell and tube heat exchangers in its workshops.

Industrial Tanks for Storage and Processing

Pisano Engineering designs and builds custom-made industrial tanks for the chemical, petrochemical, pharmaceutical, food and renewable energy industries. In our workshops in Sannazzaro de’ Burgondi (PV), we manufacture storage and process tanks from
100 liters up to 200,000 liters, certified according to the PED Directive 2014/68/EU and complying with the most stringent international standards.

What Are Industrial Tanks

Industrial vessels are containers designed for the safe storage and handling of liquids, gases and solids in the process industry. These vessels represent critical components for plant business continuity, ensuring:

  • Safe storage of raw materials and finished products
  • Maintenance of fluid quality characteristics
  • Optimal process inventory management
  • Integration with handling and control systems

Our years of experience enable us to offer customized solutions for every containment and industrial process need.
