Product Features

Easy Installation, Use, and Maintenance

The system is designed for straightforward installation without the need for complex hydraulic calculations or electrical wiring. It is easy to operate and maintain, making it ideal for both new kitchen setups and retrofits.

Wide and Reliable Nozzle Coverage

Equipped with full-cone spray nozzles that provide coverage at 30° to 60° angles, the system ensures effective distribution of extinguishing agent across all potential fire zones under the hood.

Non-Clogging Nozzles

The nozzles are specially engineered to resist clogging, ensuring consistent discharge performance even in environments with grease, smoke, and particulates.

Cartridge-Free Activation

Unlike systems that rely on gas cartridges or hydraulics, the Defender DC12S uses a mechanical triggering system that eliminates common failure points and reduces maintenance complexity.

No Replacements Required During Maintenance

The system components are built to last and do not require replacement during routine inspections, making ongoing maintenance cost-effective and predictable.

Manual and Automatic Activation

Offers dual activation modes. The system can be triggered automatically via heat-sensitive detectors or manually using a remote pull station for flexible operation.

Pressure Monitoring via Integrated Gauge

A built-in pressure gauge allows for quick, visual inspection and pressure monitoring, streamlining maintenance and eliminating the need for additional testing tools.

Micro Switch Integration

Includes a micro switch interface for automatic shutdown of gas lines, electric systems, and ventilation fans in the event of system activation, enhancing overall fire safety control.

Simplified Hydraulic Design

The system features a single-type suppression piping layout, reducing the need for complex hydraulic planning and speeding up the installation process.

Universal Kitchen Hood Compatibility

Engineered for compatibility with all types of kitchen hoods, from compact food trucks to large commercial kitchen ranges.
