Unique fire and explosion protection concepts

Maximum safety with minimum restrictions

Scheuch LIGNO is the only provider of explosion protection concepts with flame ranges of less than 3 metres. The certified safety concepts guarantee legal compliance and availability for the operator.

Conventional fire and explosion protection measures require large safety clearances, which are often not available in practice. Scheuch LIGNO has therefore developed and tested customer-specific solutions according to the installation location in question. Scheuch LIGNO can provide explosion protection concepts with a flame range of less than three metres if necessary. This makes it possible to adapt a filter erection to particular requirements, even when space is extremely limited. The certified, ATEX-compliant design is complemented by a report describing the limited impact on the rest of the hazard zone. Vehicle routes, walkways, storage areas and site boundaries are permitted within the vicinity of the filtration plant. The filter casings and separation distances have been tested in accordance with fire protection class EW90. A distance of one metre between the filter and the building is sufficient. This ensures maximum safety with minimum restrictions. A further benefit is a reduction to your insurance premium.


Extinguishing by removing oxygen using DeDust PRO

Less expense, more safety

The future of fire extinguishing rests on the principle of oxygen removal. The trend-setting technology from Scheuch LIGNO dispenses with the use of customary fire extinguishing equipment and opens the door to an extremely high savings potential. The innovative fire protection system for the ligno DeDust PRO deduster marks the beginning of a new chapter in fire protection for Scheuch LIGNO. In use for the first time, this state-of-the-art technology is producing results that are effective, safe and long-lasting. The technology’s key feature, however, is its cost-effectiveness, as owners save the ongoing maintenance and testing costs associated with extinguishing equipment by extinguishing fires through oxygen removal.

How it works

The extinguishing principle is based on the removal of oxygen which is necessary for the combustion reaction. Closures classified according to EW120 in terms of fire protection are installed for this purpose in the suction device at all inlets and outlets. These close automatically when the device is at a standstill or when the emergency-stop function is activated by gravitational force or a spring-return actuator, and extinguish the fire by removing oxygen. Combustion is brought to an end within an extremely short space of time at a oxygen concentration of 14 per cent due to the small volume of the device. In the event of a fire, the device can be supplied with extinguishing agent from outside due to the additional installation of a dry sprinkler line. This binds the dust in the device, covers it in water in the collection container and soaks it through. The device can be opened without any danger of fire or explosion and the dust collection container can be removed and emptied. H3 and GS certification marks are both proof of this application’s operational safety – this applies to all devices as of nominal width 250.

Advantages at a glance
  • No recurring maintenance and testing costs for extinguishing agents

  • No danger of erroneous operation: switching off in the case of fire is sufficient

  • Safer at a standstill, as all of the device’s openings are sealed

  • In the event of a fire, the device can be supplied with extinguishing agent from the outside

  • The device can be opened without any danger of fire or explosion
