Overview
The Ultra K34 sprinkler delivers the industry's highest ceiling-only fire protection for cold storage. By eliminating in-rack sprinklers it increases usable storage volume and reduces the risk of accidental activations. The Ultra K34 is FM Approved and intended for dry or preaction Quell / VanQuish performance-based systems; it has passed full-scale FM Global fire tests for ceiling-only storage of Class III commodities.

Benefits

• Maximize storage volume: Industry-leading ceiling-only protection for cold storage enables denser storage layouts.
• Lower costs and greater flexibility: Removing in-rack sprinklers reduces damage risk and allows reconfiguration of storage arrays without fire protection redesign.
• Proven performance: Supported by 15 full-scale fire tests across multiple commodity types, storage arrangements and ceiling/storage heights.
