What is a Gas Interlock used for?
A gas interlock system, also known as a gas safety interlock system or gas safety shut-off system, is a safety mechanism designed to prevent the release of hazardous gases in commercial or industrial settings. These systems are commonly used in places like commercial kitchens, laboratories, and manufacturing facilities where gas is used for various purposes.
The primary purpose of a gas interlock system is to ensure that gas appliances, such as ovens, stoves, or industrial equipment, are operated safely and that gas is shut off automatically in case of certain hazardous conditions. Here's how a typical gas interlock system works:
1. Current Sensors: The system is equipped with current sensors that continuously monitor the current produced by the fan motors. These sensors can detect the change in fan speed.
2. Control Panel: The gas interlock system has a sophisticated control panel design. This control panel serves as the brain of the system, processing information from the current sensors and managing the gas supply.
3. Set Point: The system can be set to a predetermined set point for minimum fan speed levels. If the fan speed levels fall below this set point, the system will activate an alarm and initiate safety procedures.
4. Shut-Off Valves: Gas interlock systems are typically connected to the main gas supply line. When a hazardous condition is detected, the system can automatically shut off the gas supply by closing gas solenoid valves. This action prevents the gas from flowing into the building or to specific gas appliances.
5. Alarms and Indicators: In the event of a gas leak or other unsafe conditions, the system may trigger audible and visual alarms to alert occupants of the building. These alarms are essential for evacuation and safety purposes.
Gas interlock systems play a crucial role in preventing gas-related accidents, fires, and exposure to harmful gases. They are typically required in many jurisdictions to ensure the safety of personnel and property in locations where gas is used. These systems are part of broader safety regulations and standards for gas handling and are typically installed and maintained by qualified professionals.
We also supply gas solenoid valves, fan speed controllers, inverters, and emergency stop buttons to complete the full kit.
What parts are supplied in a Gas Interlock System used with?
A gas interlock system is used with canopy fans, solenoid valves and fan speed controllers, all of which can be found on our website. Your ventilation engineer should be able to size the correct valve size and fan speed controller rating so they will perform at their optimum levels.
