VK502 K14.0 ESFR Dry Pendent Sprinkler

The Viking VK502 K14.0 ESFR Dry Pendent Sprinkler protects cold storage spaces and unheated warehouses from freeze damage. This specialized component installs in dry pipe systems—while maintaining compatibility with wet pipe or mixed-temperature facilities—by keeping standing water out of the sprinkler body until system activation, which eliminates ice blockages in low-temperature environments.

Engineered for strict code compliance, this model satisfies demanding life safety requirements for high-challenge storage protection under NFPA 13 standards. Its Early Suppression Fast Response technology and high-capacity discharge coefficient deliver rapid thermal activation and heavy water distribution to control fires quickly and minimize operational downtime.

• Dry Pendent Design: Prevents standing water in the sprinkler body to eliminate freeze risks in unheated or cold storage spaces.
• ESFR Technology: Provides rapid thermal response and high-volume suppression for demanding warehouse applications.
• K-Factor 14.0: Delivers a heavy volume of water to effectively suppress high-challenge fires per NFPA standards.
• Corrosion-Resistant Metals: Built with durable metal alloy construction to withstand damp, cold environments without degrading.

Ensure all installations comply with local Authority Having Jurisdiction (AHJ) requirements and current NFPA guidelines. Always review the manufacturer technical data sheets for precise rough-in dimensions and installation parameters prior to assembly.
