DynaSEALR X-series Overview Guide


Dynasafe Protection Systems AB is certified according to ISO 9001:2008



DynaSEALR D7 is a gas-tight chamber mounted on a frame and with integrated drilling equipment, enabling safe and easy handling during evacuation of gas-bottles with specified content (not oxygen or acetylene).

The drilling equipment is positioned outside the system to ensure that the internal chamber environment can be kept inert if required. The drilling is performed from above to puncture the gas-bottle through its cylindrical wall and release the gas in the bottle.


Drilling and puncturing of the gas-bottles is performed in a controlled and precise manner with adjustable feed speed to minimize heat generation. Two independent drilling units can be used, and two observation windows with the facility of fluoroscopy enables the user to see what happens inside the chamber at the drilling spot.


Any remaining liquefied gas in the bottle can be boiled away by increased temperature (to about 60 ºC) and/or suppression.

The chamber is easily decoupled, moved and maneuvered. It is manually opened by rotation of a locking ring, and horizontal pushing of the cover. The bottle is placed on the exposed loading frame, and the procedure is reversed to close the chamber. 

The chamber may also be used for transport of gas-bottles, when necessary approvals are obtained and after sealing of openings in-house.
