Hydraulic tank compensator

Hydraulic compensator
Generally mounted inside hydraulic tanks and operating with no energy source, these products compensate the variations in volume of oil or any other fluid caused by changes in temperature or volume, whilst avoiding all risk of accident for the equipment.

PRONAL compensators also ensure that tanks are completely leakproof and protect any hydraulic fluids from external pollution by means of a totally flexible membrane which isolates them from the ambient [...]

Anti-pollution inflatable plug

Anti-pollution stopper

Pronal anti-pollution stoppers have been designed to remain permanently fitted in water and sewer pipes so as to quickly stop the pipeline when accidental contamination occurs.

To do this, simply trigger stopper inflation using a remote-operated system.

Once inflated, it will prevent any toxic fluid spill or spreading of firefighting water in the pipeline.

Heat treatment installation

The BALEAR boom channel goes astray, stops and retains oil pollutions even by hydrocarbons.

They are made by elastomer or plastomer material according to the applications and are reinforced by a high resistance textile frame.
Consequently, the BALEAR anti-pollution boom is a necessary equipment during oil pollution events.

The BALEAR anti-pollution booms are present in different application areas ; calm port or open sea, and are permanent or for interventions.
