Fire Prevention Protects Automated Deep-Freeze Storage Area in North America
When the deep-freeze high-bay warehouse of Preferred Freezer Services in Richland, Washington State, was commissioned in 2015, it was the largest of its kind in the world. And it is the first building in the USA where the fire prevention is achieved through active fire prevention, i.e. with an OxyReduct® oxygen reduction system from WAGNER.
Fire Prevention Safeguards the Frozen Foods Supply on the West Coast
About the project
Three protected areas with 1.05 mill. m3 volume, 35 m high rack systems, 117,000 pallet bays and around 900,000 tons of deep-frozen foods brought into and removed from the warehouse per year. Preferred Freezer Services’ deep-freeze high-bay warehouse is unique in several respects. Even its cladded rack structure is unusual for the USA: in a country with no lack of space, high rack storage facilities are fairly rare, and deep-freeze ones even more so. Sprinkler systems quickly reach their limits with high rack systems, however, which is why the fire prevention technology from WAGNER was chosen.
About the customer
Preferred Freezer Services, founded in 1989 with a single deep-freeze storage area, has developed into a leading global provider in the field of cold storage, warehousing, distribution and logistics and currently operates 39 deep-freeze storage areas in the USA.
The height of 35 meters and the dense arrangement of the shelves promote rapid vertical fire spread in the event of an emergency.
Active Fire Prevention Safeguards Fault-Free Processes
An OxyReduct® with PSA technology, individually adapted to the structural conditions, reduces the oxygen concentration in the protected area through the controlled addition of nitrogen, thus creating a protective atmosphere. The remaining oxygen level is below the specific ignition threshold for the stored goods, in this case chips, including packaging materials.
