    • Fire protection curtains

      Fire protection curtains

      In case of fire, fire protection curtains close wall and ceiling openings. Their construction (roll-down or folding technique) and the use of different fabrics provide for a wide range of applications as well as different protection goals, classifications and time classes. The casing and guide rails of the highly flexible systems blend almost invisibly into the building and allow plenty of scope for sophisticated architecture and open room concepts.

    • Conveyor system closures

      Conveyor system closures

      Various production and logistics processes call for the most diverse types of conveyor systems. If these conveyor lines pass through fire-retardant or fire-resistant walls or ceilings, the openings required for this purpose must be provided with fire protection closures to prevent the spread of fire through the conveyor system or the goods conveyed. In the event of fire, conveyor system closures (CSC for short) must close these openings immediately and automatically. Fire resistance classified according to DIN EN 13501-2 is just as important as the smooth clearance of the closing areas in the event of a fire.

    • Smoke curtains

      Smoke curtains

      A smoke apron is a part of a smoke control system which also includes other components such as natural smoke and heat exhaust ventilators (EN 12101-2) and mechanical smoke and heat exhaust ventilators (EN 12101-3). Smoke aprons restrict the movement of combustion gases within a building in case of fire.

    • Smoke protection curtains

      Smoke protection curtains

      Once closed, smoke protection curtains (SPC) restrict the passage of smoke during the phase of fire formation, so that in the event of a fire, there is enough time to rescue people and animals from the room behind the curtain and to recover material assets without the need for respiratory equipment.

    • Tube sealings

      Tube sealings

      The solution for issues with fire protection dampers in ventilation and air conditioning systems in conveyor processes. Stöbich offers fire protection for pneumatic conveyor lines the closing elements of which are not exposed to the flow of conveyed material. This way, the closing element cannot be damaged or contaminated by abrasive conveyed goods.

    • Control units

      Control units

      Each automatic fire protection system needs a control unit. They are critical to safety, because a failure of this function means that the entire investment into a fire protection sealing has been in vain. Control units coordinate both fire detection and interaction with other control units, such as higher-level building control systems or clearing of the closing area of conveyor system closures.

System: StrainBox | Model: XL

StrainBox XL

Product description

The StrainBox XL makes it possible to transport critical and defective lithium-ion batteries in an ADR-compliant manner and to store them safely. The size and construction have been specially designed for the storage and transport of batteries and modules, such as those installed in battery electric vehicles.

All packaging in the StrainBox series has an integrated filter system that filters out toxic gases to a large extent. Dust and particles that are harmful to health are retained and the escape of solids, liquids and flames is prevented.

Due to the integrated thermal management, there is no critical temperature increase of the outer walls. If the batteries inside should accident, contamination around the packaging is prevented.

To protect people and property, the StrainBox XL also has the typical safety features that only products from Stöbich Brandschutz GmbH offer. These include the filter system, the mechanically resistant design and the integrated thermal management.

StrainBox XL

StrainBox XL
The StrainBox XL is available with valid approval as hazardous goods packaging. The capacity of this 3000 variant has been reduced to less than 3 m³ for this purpose. The space remains almost completely usable in large parts due to clever partitioning. At the same time, the legal requirements are met. All versions are also available with an electric hydraulic unit. The M variants contain a control unit with cable-connected remote control for this purpose.

Hydraulic cylinder with hydraulic unit
Electric hydraulic power unit (optional)
Locking system
Gas pressure springs
Reinforced frame with transport openings
It is possible to adapt the dimensions to customer requirements after prior consultation.
