Essential Characteristics

• closed system
• drastically reduced shrapnel dispersion
• significant reduction of the explosion pressure
• elimination of the explosion flame
• compact storage
• simple manageability and usage
• easy handling
• In the future
• shielding of remote detonators
• removable lateral surfaces

4
Exemplary fields of application

• transport and logistics (airports, train stations
  etc.)
• energy sector (power stations, power lines etc.)
• tourist facilities
• venues (sport, congresses, conventions etc.)
• shopping centres, pedestrian areas
• industry (chemical plants, oil/petroleum depots
  etc.)
• health and sanitation (hospitals, purification
  plants etc.)
• communication installations
• police stations, political establishments,
  security forces

Detonation without Protection Device
8
Shrapnel effect without Protection Device
Result significant shrapnel damage
9
Detonation with Protection Device
10
Shrapnel effect with Protection Device
Result no visible shrapnel damage
11
Explosion Pressure Reduction
Readings provided by Federal Institute for
Materials Research and Testing (BAM)
Reduction down to 45 of the pressure without
Protection Device.

Variants Fixed Construction
13
Variants Foldable Construction
In folded state the Protection Device fits into
the trunk of a passenger car.

Other SystemsGround Bomb Killer

• open at the top
• expensive (gt 20.000 )
• low reduction of shrapnel dispersion
• shielding of remote detonators not possible
• poor manageability
• German Police classification not effective

15
Other SystemsBomb Blankets

• simple blanket made of Aramid
• very low reduction of shrapnel dispersion
• poor manageability
• contact with object not avoidable
• German Police classification not effective

16
Our System

• completely closed system
• high reduction of shrapnel dispersion
• significant reduction of the explosion pressure
• elimination of the explosion flame
• simple manageability, compact storageablity
• shielding of remote detonators possible
• no contact with object
• German Police classification meets all
  requirements
