➡️Introducing the Viking VK603 QREC Pendent Sprinkler
The smart choice for Light Hazard occupancies that demand superior aesthetics, rapid response, and the lowest total installed cost.
Why settle for standard coverage when you can protect more space with fewer heads?
✅The Viking Model VK603 Quick Response Extended Coverage (QREC) Fusible Element Sprinkler is engineered to do exactly that. By covering up to 324 sq. ft. (18' x 18') with a single sprinkler, the VK603 drastically reduces material costs, labor hours, and pipe runs, all while providing the fast-acting response you need for life safety and property protection.
1. Slash Installation Costs with Extended Coverage
Designed for Light Hazard occupancies, the VK603 covers large, open spaces with fewer sprinklers.
Coverage Options: 16' x 16' or 18' x 18'.
The Result: Fewer fittings, less pipe, and faster installation. Lower material costs and reduced labor mean more profit on every job.
2. Fast Response When It Matters Most
Equipped with a sensitive fusible element, this sprinkler meets rigorous Quick Response standards. It activates faster than standard sprinklers, helping to control fires in their earliest stages—enhancing life safety and limiting property damage.
3. Built to Last in Any Environment
From elegant hotels to industrial storage, the VK603 adapts.
Decorative Appeal: Available in Brass, Chrome, White Polyester, and Black Polyester to blend seamlessly with any interior design.
Corrosion Protection: Need to spec for a corrosive environment? Choose the ENT (Electroless Nickel PTFE) coating. It is cULus Listed for corrosion resistance, ensuring longevity in challenging atmospheres like aging plants or coastal buildings.
4. No-Compromise Water Efficiency
With a nominal K-Factor of 8.0, the VK603 delivers precise hydraulic performance.
16' x 16' Coverage: Requires only 26 GPM @ 10.6 psi.
18' x 18' Coverage: Requires only 33 GPM @ 17.0 psi.
This low flow demand can lead to smaller pipe sizes and potentially reduce the size and cost of your fire pump and water tank.
5. Trusted Quality, Simple Specification
Dual Approval: cULus Listed (VNIV) and FM Approved (Class 2020)—accepted by Authorities Having Jurisdiction (AHJ) across North America.
Easy Ordering: Simple suffix system (e.g., 18277AC for Brass 165°F) eliminates confusion.
Engineered specifically for light hazard occupancies where visual appeal and space utilization matter. Perfect for protecting your brand's reputation.
The Viking VK603 isn't just a sprinkler; it's a competitive advantage. It allows you to bid lower on labor, install faster, and deliver a premium, code-compliant system that looks great and performs even better.
