Retention tanksRetention tanks


Retentions act as a double bottom for flexible tanks and reservoirs. Should there be any problem when connecting up or using a flexible tank, any loss of fuel and oil is kept within the retention to avoid any impact on the environment. Several tanks can be installed in the same retention tank, depending on dimensions. Machinery for treating all kinds of oil and fluids and transformers or hydraulic systems undergoing maintenance can also be installed within the retention tank to isolate them from their environment.

These retentions are provided with a galvanized steel metal frame composed of identical tubes and junctions to make assembly easier. They can come with a rain water drainage and filtration kit to keep them empty and clean. This kit can also be used to filter out the hydrocarbons from the rainwater in the retention tank.
