EXP Separators, also described as bladders, can be used to offset variations in the volume or oil or any other fluid associated with changes in temperature or volume, thereby eliminating any risk of damage to equipment.

These devices can be used to separate air and oil on the interior of hydraulic tanks.

PRONAL compensators can also ensure the perfect leak-tightness of tanks, with the provision of a fully-deformable membrane for the protection of hydraulic fluids from any exterior contamination and the separation of fluids from their ambient environment. These devices can also be used as hydraulic dampers.

Thanks to its robustness and the option for tailor-made construction, the EXP constitutes a high-performance inflatable hydraulic compensator.

PRONAL EXP inflatable bladders provide a solution for the offsetting of variations in the volume of fluid in tanks in the nuclear or offshore sector, the separation or equalization of two fluids, whether liquid or gaseous, the sealing of a hydraulic circuit or the pressurization of a hydraulic circuit in submersed hydroelectric plants.
