Hydraulics Industry
In the hydraulics sector, PRONAL provides components whose principal role is to protect hydraulic circuits:-
- The range of elastomer compensators ensures the separation of two mediums (liquid and/or gaseous) and protects oil from external aggression such as dust, humidity ... they are generally mounted inside oil tanks,
- Arrester-separators are used by tank and pressure vessels manufacturers as well as by accumulator manufacturers to neutralise the effects of excessive pressure,
In the electricity sector, PRONAL supplies flexible separators to compensate for fluctuations in the volume of oil contained in instrument transformers or power transformers resulting from variations in temperature.

Glass Industry
PRONAL is involved in the series production of flexible gripper bags for use in the hollow glassware industry and for handling all types of bottles, thus optimising palletisation and de-palletisation.
Flexible vacuum bags are used in the heat-treatment of laminated glass by OEMs who supply automobile windscreens.
The development of safety glass in the construction and sectors other than the automotive sector, persuaded Pronal to develop quick-lock flexible bags.
These bags have the advantage of receiving very thick and curved glass.
