Shipping calculated at checkout
The Viking VK174 Quick Response Dry Sidewall Fire Sprinkler is engineered for installation in dry pipe and preaction fire suppression systems protecting environments vulnerable to freezing temperatures. This compact horizontal sidewall assembly mounts directly to walls in cold storage facilities, industrial warehouses, and commercial spaces where overhead piping is impractical or freeze-ups present a structural hazard.
The dry barrel design prevents water from sitting inside the nipple prior to operation, eliminating ice blockage risks in subzero conditions and ensuring immediate water discharge when the heat-activated mechanism triggers. Designed to satisfy NFPA 13 installation requirements for commercial and industrial life safety systems, this sprinkler meets strict code compliance for modern builds and retrofits. The sensitive quick-response heat element provides rapid fire detection to cut response times and minimize structural damage, while the corrosion-resistant high-grade brass construction delivers long-term durability in aggressive industrial environments.
