Oil storage tanks

Dielectric oil storage tanks are ideal for temporary storage requirements during power transformer commissioning operations. These flexible tanks can also be used to store oil during on-site maintenance phases or as part of the recycling or treatment of dielectric oil.

This real “flexible oil tank” holds 1 to 300 m3. The accessories are optimized to allow quick and easy connection to the used oil regeneration units. Combined with Pronal oil retention systems, this flexible storage solution ensures operations that are absolutely safe and risk-free for the environment.
