What You Will Learn

Active fire prevention with oxygen reduction systems represents a formidable alternative to sprinklers in fully automated deep freeze warehouses.

NewCold, a global 3PL leader in the development and operation of automated cold storage for food processors, made sure both the warehouses they built in the US had the same protection of their European properties. In a business where improved cubic storage capacity is key, nothing but low-oxygen fire prevention would do.

This 150,000-sf high bay warehouse does the job of a traditional 600,000 sf warehouse, by reducing the footprint by nearly 75 % for warehouse space alone. Through automated processes, manned forklifts become virtually unnecessary in this facility. The Automatic Storage and Retrieval System (ASRS) uses robotic conveyors and cranes to store, move and retrieve products in a low-oxygen storage area. Storage capacity is maximized by pallet racking that can reach a height up to 135’, and vertical and horizontal racking that runs virtually uninterrupted throughout the length and width of the building.

The oxygen level is reduced to 16.5 % by means of a nitrogen exchange process, and strictly controlled by O2-sensors. The likelihood of a fire starting, or spreading is dramatically reduced, and people, property, and facility remain safe and protected. In addition, this kind of fire protection provides several other advantages.

Key Takeaways

• Preserving life, property, and business continuity with low-oxygen fire prevention
• How a state-of-the-art low-oxygen system works
- Principles of oxygen reduction
- Component overview
- System design criteria
• Current global standards
• Low Ox and OSHA regulations
• How one of the key 3PL players responded to the threat of fire
• Fire protection in automated frozen warehouses is challenging – Low Ox is the solution
• Active fire prevention with low-oxygen systems is an innovative alternative in the US, and already in use in Europe for 20 years
• Design of low-oxygen system is case-by-case, depending on project requirements
• Technology (Automation and/or Fire Protection) requires close collaboration between stakeholders to make it happen
