Gas Interlock Systems cut off gas flow in the event of kitchen extract fan failure. This is now a mandatory requirement in most commercial kitchens.
Sensors placed either side of the ductwork fan monitor air pressure. They are connected to an air differential switch which is activated when the pressure difference changes. Alternatively, the current taken by the fan can be monitored by a fan power sensor. The 230V GIS monitors this switch/sensor and in the event of fan failure will close the gas solenoid and cut off the gas flow to kitchen appliances.
When is a Gas interlock system a mandatory requirement?
- - On installation of a completely new exctraction/ventilation canopy.
- - On installation of a completely new gas pipework run
- - On installation of a completely new cook line or layout
- - With any fitting of Category 'B' equipment e.g. combination ovens, deep fryers, grills, charcoal griddles. This includes replacements to an existing layout.
