Case study: Deep-freeze high-bay warehouse of KLM

Fire Prevention from WAGNER Protects Fully Automated Deep-Freeze High-Bay Warehouse in a Class of its Own

When commissioned in May 2013, KLM’s deep-freeze high-bay warehouse was the largest of its kind in Germany. Located at the Rheine site in Westphalia, it offers over 8,500 m2 of storage space for 68,400 pallets – all protected against the outbreak of fire by a WAGNER oxygen reduction system with VPSA technology.

Active Fire Prevention for Ice Cream and Frozen Food

About the project

At the time of its commissioning, the fully automated deep-freeze warehouse entered the history books as ‘Germany’s largest refrigerator’. By expanding its existing warehouse, KLM was able to increase its total capacity to 90,000 spaces. The fire prevention solution, based on WAGNER’s OxyReduct® oxygen reduction system, guarantees uninterrupted safety. The VdS-approved solution is also both cost and energy efficient.

About the customer

KLM, a subsidiary of the logistics service provider NewCold, has offered full-service logistics for over 30 years. The head office in Rheine handles 7,000 pallets per day.

Protection objectives

  • Operations
    Interruptions to the logistics chain and other business processes as a result of fire must be prevented.
  • Asset protection
    The frozen goods stored must be protected against smoke, soot and any possible consequential fire damage due to extinguishing measures.
  • Personnel protection
    KLM employees must be safe from fire at all times.
  • Environmental protection
    The formation of hazardous materials due to fires and extinguishing agent residues must be prevented.

Risk analysis

  • Techn. defects
    Defects in refrigeration systems, overheating of conveyor motors or possible cable fires are a fire risk
  • Dry atmosphere
    The humidity in a cold store is very low. This makes it very easy for a fire to spread.
  • Packages
    The fire load of packaging materials such as paper, cardboard and films is very high.
  • Construction
    A fire can spread quickly in the narrow and high shelves. Burning, falling parts are another danger.

Precautionary Fire Prevention

The nitrogen needed to reduce the oxygen level is directly obtained from the ambient air in a particularly energy-efficient and environmentally friendly manner using generators with VPSA technology. WAGNER has installed three VPSA systems at KLM, each with a supply volume of 240 m3/h; one of these serves as a 50% redundancy system to meet the emergency concept requirements established in the building permit.


Customer benefits

  • Efficiency
    The state-of-the-art VPSA technology is energy-saving and thus climate-friendly.
  • Installation & Service
    WAGNER has a dense network of branches throughout Germany; the system itself is easy to maintain.
  • Safety
    The fire protection solution from WAGNER has VdS recognition and thus offers certified safety.
