Case Study: DIAMANT Zucker High-Bay Warehouse

Active Fire Prevention in High-Bay Warehouse – a Container Solution

Sweets are omnipresent in the factories of the sugar manufacturer Pfeifer & Langen. With several locations in the EU, the company, founded in Cologne in 1870, is one of the largest sugar manufacturers in Europe. For one of the production sites in Poland a newly built high-bay warehouse will go into operation in the middle of this year - with suitable fire protection from WAGNER Poland.

Sweetener from Beet and Cane Receives Fire Protection with Oxygen Reduction

About the project

Pfeifer & Langen Polska S.A. has built a new high-bay warehouse at its production site in Sroda Wielkopolska near Poznań in 2019. Sugar specialties such as cinnamon sugar or syrup are stored here. Up to 24,000 pallet spaces are planned in the 35 meter high and 140,000 cubic meter warehouse. It is directly connected to the sugar factory via a lock. Storage and retrieval of the goods as well as their commissioning are fully automated.

About the customer

Pfeifer & Langen has been manufacturing sweet products from beet and cane for the food industry and end consumer for 150 years and sells them under the name DIAMANT Zucker. The company employs about 2.400 employees all over Europe.

Protection goals

Risk analysis

  • Electrical components
    There is a high degree of automation in the warehouse and production halls and thus a high proportion of electrical components.
  • High fire load
    The packing density of the goods is high and the packing material is cardboard. In addition, the sugar is stored on pallets for further processing.
  • Chimney effect
    With a storage height of about 35 meters and due to narrow construction the chimney effect in the warehouse is favored in case of fire.

Solution in Container – Fire Prevention System is Placed Outside the Warehouse

Four OxyReduct® V-Line systems together with early fire detection form the basis of the fire protection solution. The V-Line systems produce nitrogen from the ambient air and introduce it into the previously defined protected area. In this way, the oxygen concentration is reduced below the specific ignition limit of the materials stored there. In this protective atmosphere, a fire cannot develop any further, nor can it spread any further. This solution also includes a system for early fire detection with aspirating smoke detectors. The TITANUS® aspiration points permanently take samples from the ambient air. The finest pyrolysis particles are thus detected as early as possible. The special feature of the solution at Pfeifer & Langen is that a large part of the fire protection technology such as nitrogen generators and switch cabinets was installed in a container next to the high-bay warehouse. "An external operating room is thus ideal for maintenance, as it is easily accessible. In addition, construction costs could be saved because no separate technical room had to be built in the warehouse for the fire protection system," says Ireneusz Bruski, Managing Director of WAGNER Poland, explaining the reasons for the container solution.

Customer Testimonial

Andrzej Biedulski, Project Manager at Pfeifer & Langen Polska S.A.

The most important thing in this case is to protect the stored sugar. A foam- or water-based solution was therefore ruled out for us from the outset.
