PRONAL Flexible Tanks
PRONAL - SOFT WALL PLASTIC TANKS AND POOLS 
Flexible storage tanks are the perfect solution for storing (temporarily or permanently) and/or transporting all types of liquids, including: drinking water, hydrocarbons, chemical solutions, food products, industrial waste, or sludge. Also known as flexible bladders or flexible covers, they are made from either elastomer or plastomer, depending on their application. The tanks are reinforced with extra-strong textile reinforcement effectively making them highly tear-resistant.
Flexible storage tanks can be rapidly deployed, are easy to install, and are maintenance-free. Pronal flexible storage tanks represent an ideal and economical solution for a wide range of activities: military, agricultural, construction, energy, industry, nuclear, fire-prevention, …
Our range of tanks can also transport any type of liquid when mounted on truck flat-beds, by suspension under helicopter, by towing behind a vehicle … Some versions can be dropped from the air from a height of several tens of meters.
Our flexible tanks are used worldwide and have a multitude of potential uses and users.

Flexible fuel tanks represent the best logistical solution for storing hydrocarbons. Their modest volume when “emptied and folded” is only equal to about 1% of their nominal storage capacity meaning that they can be simply and rapidly transported, no matter where they are to be installed.
The strength of these tanks coupled with the rapidity of their installation (less than 4h for a 300 m3 tank) means that they have become the preferred fuel storage system for organizations working in remote areas.
These flexible tanks can be used to establish both primary or secondary fuel depots. They provide continuity in the petrol supply chain by facilitating a range of operations:
- The storage of jet fuel for refueling aircraft or other vehicles,
- Providing power plants with diesel,
- Supplying mining vehicles with fuel,
- Supplying fuel for base-camp generators …

The open flexible tanks – Opentanks also known as “onion tanks”, type self-supporting tanks, are circular and comprise an inflatable or foam float.
Compared to closed flexible tanks, they allow quickly storing raw or drinking water poured into the opening at the top. They are also quick and easy to clean, to effectively eliminate any pollution of the stored liquid (sludge, leaves, etc.).
These open flexible tanks are generally designed to store raw water dedicated to civil defence or humanitarian needs. This onion tank can however be used for storing industrial effluents or polluted waters.
