VK553 K11.2 SR Upright Fire Sprinkler

The Viking VK553 K11.2 SR Upright Fire Sprinkler is engineered specifically for in-rack fire protection within warehouses and storage facilities. It installs in upright positions within storage rack assemblies to deliver targeted water distribution directly over densely packed inventory, minimizing fire damage and operational downtime.

This unit integrates seamlessly into standard wet pipe fire protection systems for both retrofits and new installations. It satisfies NFPA 13 installation standards for storage facilities, supporting regulatory compliance and critical life safety protocols.

• Upright Orientation: Designed specifically for in-rack storage installation to target fire hazards where they commonly originate.
• Rapid Response Glass Bulb: Heat-sensitive thermal element triggers immediate water discharge at critical operating temperatures.
• Water Shield Technology: Directs controlled water spray to suppress fire effectively while minimizing water waste and adjacent inventory damage.
• High-Grade Metal Construction: Built with robust metallic components to withstand mechanical impacts common in active warehouse environments.
• System Compatibility: Integrates smoothly with standard wet pipe fire protection systems for straightforward retrofits or new builds.

Contractors and facility managers must verify local Authority Having Jurisdiction (AHJ) requirements and review spacing, obstruction, and storage height rules before installation. Always consult the manufacturer's technical data sheets to ensure proper system design parameters are met.
