Emergency shutdown systems are essential for LNG dispensers due to cryogenic hazards and high-pressure conditions. They include automatic shut-off valves and pressure sensors that stop flow instantly during abnormal events.
When a system detects a leak, excessive pressure, or a mechanical failure, it triggers the emergency shutdown. Visual and audio alarms alert operators to take corrective action.
These mechanisms protect both personnel and equipment, ensuring safe operation even under unforeseen circumstances, which is crucial for public and commercial fueling stations.
