Advantages

The combination of a fuel cell system from QuattroGeneration with an Oxeo Prevent oxygen reduction system does not simply enable dependable fire protection of a cold store. Operating costs can be significantly reduced via the energy-, heat- and cold production of the fuel cell system and the costs of the nitrogen generator which would otherwise be necessary can be completely saved. The overall system is therefore an extremely efficient solution for the various requirements of a cold store.

  • Fires cannot occur at all
  • No damage from heavy smoke production or extinguishing side effects
  • Technical systems and processes remain available
  • Reduction of operating costs via maximum efficiency
  • Safety and redundancy in the energy supply
  • High level of flexibility thank to the modular nature of the system

Function

Basic principle of Oxeo Prevent

Oxeo oxygen reduction systems are the ideal solution, since the conditions for their use — no permanent presence of people in the storage facility, a well-sealed building shell and very low infiltration of fresh air caused by bringing in and removing goods — are also required to maintain the desired temperature level. The operating principle is simple: the air oxygen content is continuously lowered through the controlled supply of nitrogen in the protection area so that a “fireproof” atmosphere occurs. Thus the outbreak of open fires can be prevented.

Combination with a fuel cell

Conventional Oxeo Prevent oxygen reduction systems generate the nitrogen necessary for this purpose via a nitrogen generator immediately on site. Significantly more economic is the combination of a fuel cell system from our partners Fuji Ntelligence. The QuattroGeneration system generates power, heat and air conditioning coolness and (as a by-product) oxygen-depleted air. This can be used permanently for the Oxeo Prevent system and makes a nitrogen generator superfluous.

Application

Refrigerated storage

Protection zone

Refrigerated storage is widespread especially in the food industry and in the related, downstream commercial operations. The goods and products are stored for purpose at temperatures of up to -40 °C. The necessary heat insulation often consists of non-flammable or flammable insulation materials with varying fire performance, often in the form of sandwich elements. Rack storage is predominant in refrigerated storage facilities

Risks

  • Dry air promotes the rapid spread of fire
  • Additional fire loads when using flammable insulation material
  • Extinguishing water without antifreeze additives will freeze over very quickly.

Fire Protection

Oxeo Prevent fire prevention systems are the ideal solution for refrigerated storage facilities, since the conditions for their use — no permanent presence of people in the storage facility, a well-sealed building shell and very low infiltration of fresh air caused by bringing in and removing goods — are also required to maintain the desired temperature level. Moreover, they offer perfect protection for the storage of foodstuff that is sensitive to smoke and temperatures. Oxeo Prevent fire prevention systems are mostly used in combination with HELIOS AMX5000 aspirating smoke detectors with a highly sensitive setting to ensure earliest fire detection. Heated aspirating outlets ensure their proper operation in refrigerated areas. Though Oxeo Prevent can only prevent a smoldering fire from turning into an open fire, the fire and the cause of fire would remain permanently undetected in the absence of an earliest fire detection system. Alternatively, sprinkler systems can be installed in such conditions — here ideally fitted with ESFR sprinklers. If there is a sufficiently spaced, frost-free intermediate area above the ceiling available, we recommend pendent Viking ESFR dry sprinklers. Combined with a Minimax PipeGuard Antifreeze system, sprinkler systems can be used in refrigerated storage facilities at a temperature of up to -40 °C.
