Minimax Protects Deep-freeze Warehous of Coppenrath & Wiese

Sustainability in fire protection: Minimax has equipped Coppenrath & Wiese's deep-freeze warehouse in Osnabrück with a special oxygen reduction system: Minimax OXEO ECOPREVENT FC/VG.

The award-winning system generates nitrogen by means of a connected fuel cell. This solution is particularly economical: During power generation, the fuel cell produces clean, nitrogen-rich exhaust air as a by-product, which can be used for oxygen reduction. With this environmentally friendly solution, a return on investment can even be achieved, since the significant energy costs of the nitrogen generator that would otherwise be required are eliminated.

The Coppenrath & Wiese deep-freeze warehouse based in Osnabrück comprises 97,540 m3 in three protected areas. The temperature is around -22 °C. By introducing nitrogen, the oxygen concentration is reduced from 21% by volume (normal) to approx. 15% by volume and can still be accessed by verified personnel.

Saving up to 650 tons of CO2 annually
The fuel cell consistently delivers just under 100 kW of electricity (equivalent to 876,000 kWh/year) and just under 100 kW of thermal power, which the company uses to cover part of its energy load (electricity and heat). Whereas 132 kW was consumed with the old system, 86 kW of electricity is now generated on balance.
