Gas interlock systems

 

Gas interlock systems are crucial safety features found in commercial kitchens, schools, laboratories, and industrial settings where gas appliances are used alongside ventilation systems. They function by ensuring that the gas supply to appliances like ovens, grills, and fryers is automatically shut off if the ventilation system fails. This prevents the buildup of explosive gas mixtures and the risk of fires and explosions.

 

How gas interlock systems work?

 

Components:

  • Gas solenoid valve: This valve controls the flow of gas to the appliances.
  • Pressure switches: These monitor the pressure in the ventilation system's ductwork.
  • Control panel: This houses the system's electronics and displays alarms and status information.

 

Operation:

  1. When the ventilation system is turned on, and airflow reaches a safe level, the pressure switches signal the control panel.
  2. The control panel then opens the gas solenoid valve, allowing gas to flow to the appliances.
  3. If the ventilation system fails and airflow drops below a safe level, the pressure switches trigger the control panel.
  4. The control panel immediately shuts off the gas solenoid valve, stopping the gas flow to all appliances.

 

 

Benefits of Gas Interlock Systems:

 

  • Enhanced safety: They significantly reduce the risk of gas explosions and fires by automatically shutting off the gas supply in case of ventilation failure.
  • Compliance with regulations: They are often mandatory in commercial kitchens and other settings due to safety regulations.
  • Peace of mind: Knowing that a system is in place to prevent gas leaks and accumulation of fumes in the kitchen.

Choosing the Right Gas Interlock System:

  • Current monitoring type: We recommend this type of gas interlock panels because they are a lot more reliable than air pressure sensor type systems.
  • Air pressure switch type: It is normaly cheaper and less reliable than corrent monitoring type.Ensure the system is compatible with the type of gas used (natural gas, propane, etc.).

Remember, regular maintenance and testing of gas interlock systems are crucial for their proper functioning. Only qualified technicians should perform these tasks.

I hope this information is helpful! Feel free to ask if you have any further questions about gas interlock systems.
