The Merlin CT1750 Gas Interlock System is a high-performance gas safety solution tailored for commercial kitchens with solid fuel appliances, including charcoal ovens and grills. It functions as a safety interlock between the kitchen’s ventilation system and gas solenoid valve, only allowing gas to flow when ventilation is confirmed as active.
On startup, the system automatically performs a gas proving test, checking for gas leaks or appliance faults before enabling gas supply. If hazardous gases are detected during or after operation, the system responds by automatically increasing fan speed, even if the panel is turned off—providing a robust safety failsafe.
With support for up to four fans using current monitors or air pressure differential switches, and full BMS integration, the Merlin CT1750 offers precise control, regulatory compliance, and enhanced safety monitoring across a wide range of kitchen installations.
