Viking VK172 Quick Response Dry Pendent Fire Sprinkler

The Viking VK172 Quick Response Dry Pendent Fire Sprinkler provides reliable fire suppression in unheated spaces, loading docks, and cold storage facilities where freezing temperatures threaten standard wet pipe systems. Installing directly into dry pipe or preaction assemblies, this component features a specialized dry barrel configuration that maintains an airtight seal. This design keeps water out of the piping until the thermal element activates, preventing costly freeze damage and pipe bursts in exposed commercial and industrial environments.

Engineered for compliance with NFPA 13 and NFPA 25 installation and maintenance standards, this UL Listed and FM Approved sprinkler satisfies strict life safety codes for hazard protection. The sensitive quick response thermal element detects early fire heat to suppress flames rapidly, minimizing structural damage and enhancing overall facility safety.

Key Features & Construction

• Dry Barrel Design: Keeps water safely upstream from freezing areas to eliminate pipe bursts in cold storage rooms, parking garages, and warehouses.
• Quick Response Technology: Employs a highly sensitive thermal element that triggers fast activation at the earliest stage of a fire.
• Durable Construction: Fabricated from premium brass and corrosion-resistant alloys to withstand demanding operational conditions and minimize maintenance requirements.
• Plain Barrel Configuration: Optimizes water delivery efficiency immediately upon system activation.

Technical Specifications & Compliance

Contractors and facility managers must verify all local Authority Having Jurisdiction (AHJ) mandates and consult the official manufacturer engineering bulletins prior to system design and installation.
