VK549 Quick Response Dry Pendent Sprinklers

The Viking VK549 Quick Response Dry Pendent Sprinkler is engineered for fire protection in environments prone to freezing temperatures, such as unheated warehouses, parking structures, and cold storage facilities. Installed in dry-pipe or preaction fire suppression assemblies where water retention in pipes presents a freeze hazard, this specialized component features an extended barrel configuration that keeps the water supply safely behind a heated boundary until system activation.

Designed for compliance with NFPA 13 standards, this sprinkler satisfies critical commercial life safety requirements for properties exposed to sub-zero conditions. The rapid heat-sensitive activation mechanism responds swiftly to early-stage fires, meeting stringent regulatory compliance while maintaining operational readiness in harsh, dusty industrial spaces.

• Dry-Pipe Configuration: Prevents water retention within the assembly, eliminating freeze damage and pipe bursting risks in unheated environments.
• Quick Response Mechanism: Incorporates a rapid heat-sensitive activation system to contain early-stage fires and reduce property damage.
• Robust Construction: Fabricated from durable brass, stainless steel, and ductile iron materials.
• Corrosion-Resistant Coatings: Enhanced with Nickel PTFE coatings for extended service life in harsh industrial conditions.
