Box sealing system DS 90 / 120 mm

The new box sealing system DS 90 / 120 mm covers an additional range of applications in building fire protection. The increased diameter makes it possible to use a larger number of cables and electrical installation conduits and also greater diameters. With this system, it is also possible to mix the installation of conduits and cables. In addition, full population, as with the DS 90 / 74 mm, allows use of the system in all fields of building technology. Because no additional materials are used, non-destructive retrofitting is also possible. The tried-and-tested screw fixing permits clean, safe and secure installation.

Secure, visible, certified fire sealings
Seals wall feed-throughs
Automatic sealing of the joints and gaps between cables - no filling and smoothing
Non-destructive retrofitting
Also for mixed population of bundles of cables and conduits

Examples of use

Can also be used as a reserve sealing.

Full population with sheathed cables up to Ø 29 mm.

Mixing of cables and conduits.

Horizontal alignment is possible with a distance of 50 mm.

Technical information DS 90 / 120 mm

Lamellae arranged on the inside of the sealing cylinder ensure fast closing if a fire breaks out.

The sealing element with integrated cooling ribs guarantees clean cable and conduit routing.

Easy insertion of the sealing cylinder into the installation opening.

Automatic room separation - no gaps or filling of joints.

Population of box sealing system DS 90 / 120 mm

Mixed population of sheathed cables and conduits.

Can also be used as a reserve sealing.

Full population with sheathed cables up to Ø 29 mm and conduits up to M63.

Installation conduits can be fitted as reserve conduits.

Installation

The box sealing system DS 90 / 120 consists of two parts which easily fit together.

Cut installation opening with a cutter Ø 120 mm (e.g. Art. No. 1084-20).

Press the sealing cylinder into the installation opening.

Fix sealing cylinder by tightening the screws (same procedure as with cavity wall boxes).

Feed sheathed cables and conduits through the sealing cylinder.

Close conduit ends smoke-tight (e.g. with KAISER sealing plugs).

Fit the two-part sealing element round the bundle, close it and connect it to the sealing cylinder by means of the bayonet fitting.

The sealing and the necessary room separation can also be used as a reserve sealing.

Horizontal alignment of the sealings is possible with a clearance of 50 mm.

Non-destructive retrofitting of single cables and conduits

Loosen the sealing element by turning it a quarter of a turn and open it.

Open the sealing element and remove it.

Insert the new cables and conduits.

Fit the sealing element and secure with a 1/4 turn to the right.

Installation of box sealing system DS 90 / 120 mm in masonry

Cut installation opening - depending on wall thickness - with a core drill 150 mm.

Using plaster, mortar or fast cement, press the sealing cylinder into the installation opening and feed the cables or conduits through.

The sealing collar ensures tight room separation, even when openings are not clean, and prevents plaster, mortar or fast cement from being pressed out.

Place the sealing element on the sealing cylinder and secure it with a 1/4-turn (bayonet fitting).

The table shows examples of cables which can be used on the basis of the maximum permitted diameter. The main factor is the minimum stated standard diameter acc. to DIN VDE 0250-204.
