The Merlin 3000S Gas Interlock System is an advanced solution that combines gas proving , energy-saving ventilation control , and real-time sensor monitoring into one compact, high-performance unit. Designed specifically for commercial kitchens , this system adjusts ventilation fan speeds based on gas usage, CO2 levels, smoke, and heat detection , optimizing airflow and reducing energy consumption.
With two built-in 0–10VDC outputs , the Merlin 3000S dynamically regulates fan speed, increasing extraction when gas or heat levels rise and reducing it when activity is low—leading to lower operational costs and quieter working environments .
Featuring a full-color TFT display , the system provides live diagnostics, calibration access, and system status. It also supports BMS integration , emergency shut-off buttons , and compatibility with methane, LPG, and CO detectors , offering full-spectrum kitchen safety and regulatory compliance.
