Flexible tanks of the “onion” type can be effectively deployed in emergency situations. In comparison with closed flexible tanks, open-topped onion tanks offer the advantages of rapid filling from the top and full interior cleaning.
Applications for the PRONAL open-topped flexible tank include the storage of fire extinguishing water, use as a decantation basin, or as a buffer storage facility for chemical effluents prior to treatment.
Lightweight and flexible, these tanks are easily transported from one site to another.
Open-topped flexible tanks range in capacity from 1m3 to 20m3, with an option for tailor-made manufacture.
