Wet, dry, pre-action, and deluge sprinkler systems with software-based hydraulic calculations — engineered for warehouses, industrial facilities, commercial buildings, and special hazards.
Viking Corporation's sprinkler range covers over 463 products across commercial, storage, residential, extended coverage, and special application categories — all FM Approved and UL Listed.
The most common and reliable system type — water is constantly maintained in the piping, providing the fastest possible response when a sprinkler head activates. Suitable for heated buildings without freezing risk. Viking offers a full range of pendent, upright, concealed, and sidewall sprinkler heads for standard and extended coverage applications, with K-factors from 2.8 to 25.2.
Pressurized air or nitrogen fills the piping instead of water — essential for unheated spaces, cold storage, and car park structures subject to freezing. When a sprinkler opens, air escapes, the dry valve trips, and water flows. Viking dry valves are available in sizes 2" to 8" and are certified for FM Approval.
Pre-action systems require two independent triggers — a detection signal AND a sprinkler head opening — before water releases. Single-interlock or double-interlock configurations. The preferred choice for data centers, archives, and areas where accidental water discharge would cause serious damage. Viking Viking pre-action valves integrate with fire alarm panels for coordinated response.
All sprinkler heads are open — water is delivered simultaneously across the entire protected area when the deluge valve activates. Used where rapid total coverage is essential: aircraft hangars, transformer bunds, chemical process areas, and high-hazard manufacturing. The Viking deluge valve is the heart of the system, available with pneumatic, hydraulic, or electric release.
Directed water spray for transformer protection, cable tray protection, LPG vessel exposure protection, and structural steel cooling. Spray nozzles are designed to produce a specific discharge pattern and density over the protected surface. Viking offers directional spray nozzles and open spray heads in a range of orifice sizes and deflector patterns.
In-rack and ceiling-level sprinkler protection for high-pile storage, racked storage, and high-hazard commodity classes. Viking storage sprinklers are designed to deliver the high flow rates and discharge densities required by NFPA 13 Chapter 20 and FM Global DS 8-9 for challenging storage configurations.
Every sprinkler system we design is supported by full hydraulic calculations — not estimates — verifying that the required water density reaches every sprinkler in the most demanding design area.
Software-based hydraulic analysis verifying flow, pressure, and density requirements at the most demanding design area — submitted with every proposal.
Flow test data analysis and pump curve matching to confirm the available water supply meets the system demand with the required residual pressure.
Hazard assessment to NFPA 13 and FM Global data sheets — Light, Ordinary, Extra Hazard — determining the required discharge density and design area.
Sprinkler head layout coordinated with architectural and structural drawings to maintain required spacing, obstructions, and ceiling configurations.
Piping network sized to minimize friction losses while meeting velocity limits — feed mains, branch lines, and drops specified to NFPA and FM requirements.
Complete hydraulic calculation report, design drawings, equipment submittals, and material schedules — ready for consultant and Civil Defense approval.
