Extraction & Interlock systems

Gas Interlock Systems, a mandatory requirement in most commercial kitchens. Our engineers can install the CaterGuad Gas Interlock Systems (GIS) so that your business complies with the required regulations and so that you have peace of mind regarding appliance safety.

What GIS does?
Monitors either Air Pressure Differential Sensors mounted in the extraction and air supply ductwork and/or Fan Power Sensors. In the event of fan failure or significant air flow reduction (As calibrated by installation engineer), the sensors will actuate the Mechline GIS, which in turn closes the gas solenoid and cuts off the gas supply to the kitchen appliances. It's easy to use too, with one button operation.

When is it mandatory?
On installation of a completely new extraction/ventilation canopy, on installation of a completely new gas pipe work run, on installation of a completely new cook line or layout, and with fitting of certain appliances such as combination/convection ovens and some deep fryers.
