Oil Storage Tank

The oil storage tank is the ideal solution for temporary or permanent storage of dielectric oil. PRONAL flexible tanks are made from technical fabrics coated with elastomer, which are particularly suitable for oil storage. These fabrics are also resistant to extreme weather conditions. 

This tank is mainly used for: 

  • On-site maintenance operations 
  • Commissioning operations on transformers 
  • Rapid expansion of storage facilities 
  • Storage awaiting recycling/treatment

This oil storage tank ranges from 1 to 300 m3. Its accessories are adapted to the most commonly used oil regeneration units. The connection is easy and quick to set up. 

Indeed, this flexible tank allows a real saving of time; its installation is fast and simple and requires no building permit (depending on the size of the tank).  

Lightweight and easily transportable, they can be used to store several hundred cubic meters in a few hours. 

This oil tank can be associated with PRONAL retention systems. Thus, it will ensure totally safe operations without any risk for the environment. 

Moreover, for transport needs on remote sites, we offer oil storage tanks dedicated to transport in containers (LCI) or on trays (Dynamic).
