How Does the Kitchen Hood Fire Suppression System Work?
The wet chemicals in the system react with the burning oils to create a soapy coating that cuts off the grease and oil's oxygen supply, preventing them from igniting further. Potassium acetate, potassium carbonate, and potassium citrate are the substances that are frequently discovered.
The water in the system cools the oil and grease by lowering their temperature. The system, which consists of nozzles targeted to the burners and fryers, releases the agent-water mixture when it notices any unusual activity. This mixture is nothing more than a large-scale fire extinguisher contained in a box and connected to the nozzle by a conduit
A manual pull station with a switch may also be used to activate the thermal link that typically activates the connection controlled by a valve. As soon as it activates, the extinguishing agent from the cylinders is discharged through the nozzles, controlling the situation.
The entire system is built out of stainless steel to prevent corrosion and maintain the heat effect. In order to keep the fire in the kitchen and prevent it from spreading throughout the building, several systems may interact with ductwork dampers.
