Intermittent sealing solutions, the inflatable seals consist of a customized section and a valve.

Used to effectively free the seal when insulation is not needed, they are able to withstand over 300,000 inflation and deflation cycles, resulting not only as a back up solution for intermittent application, but a effective long life  solution.

Profiles

The profile (or section) of the inflatable seals are custom designed according to the size of the seats in which the seals must be housed and according to the space they must “cover” during the activation phase.

The inflation and deflation, which correspond respectively to the activation and deactivation phases, take place through the vulcanized valve directly in the profile. The types of seals that can be designed are almost infinite according to the innumerable combinations of profile / profile development / design and possible valve position.

The technology developed by the R&D technicians has also led to the creation of inflatable seals resistant up to 10 bar of operating pressure, thanks to special internal reinforcements.

Compliance with Regulation EN45545: 2015

Over 40 years of experience in the railway sector have allowed ATP to study and test a special joint, capable of withstanding over 300 thousands of inflation and deflation cycles. In particular, this gasket, tested and installed on trains currently in circulation, complies with EN45545: 2015, Requirements R22-23, HL1, HL2, HL3, relating to the behavior to fire and to smoke emissions.

A solution Appliable in other Sectors

From consolidated experience in the railway sector and thanks to the development of inflatable seals with or without internal reinforcement, ATP is applying this solution also in other sectors including the food, pharmaceutical and naval sectors.
