VK512 K25.2 ESFR Dry Grooved Pendent Sprinkler System

The Viking VK512 K25.2 ESFR Dry Grooved Pendent Sprinkler is engineered for installation in dry pipe fire suppression networks protecting unheated, freezing environments such as cold storage, warehouses, and manufacturing facilities. Designed for overhead pendent positioning, this assembly prevents water from standing in the barrel within freeze-prone zones, maintaining system readiness and averting catastrophic pipe bursts.

This component satisfies rigorous fire protection requirements under applicable NFPA standards—specifically NFPA 13 for dry pipe systems in vulnerable commercial and industrial spaces. By integrating Early Suppression Fast Response (ESFR) technology, the sprinkler delivers high-density water discharge at the onset of a fire, fulfilling code mandates for rapid containment in expansive storage layouts.

Key Features & Construction

• ESFR Technology: Activates quickly with high-density water flow to suppress fires at their onset in industrial spaces.
• Grooved Connection: Simplifies mechanical installation, creates a secure and leak-resistant seal, and minimizes maintenance downtime.
• Freeze Protection: Keeps water out of the unheated drop area to eliminate ice blockages and pipe damage.
• Corrosion-Resistant Build: Utilizes durable materials designed for long-term reliability in harsh, cold environments.
• High-Capacity Orifice: Features a K25.2 rating to supply the massive water volume required for early suppression.

Technical Specifications & Compliance Table

Verify all local Authority Having Jurisdiction (AHJ) mandates, spacing parameters, and structural limitations before commencing system design or installation. Always consult the manufacturer's official technical data sheets for specific assembly lengths (including 19.5", 25.5", 31.5", and 37.5" options) and operational parameters.
