HI-FOG® systems for the food industry can have a wide variety of configurations based on project-specific requirements. Presented here are sample configurations for industrial oil cookers and ovens.
HI-FOG® systems for industrial oil cookers and deep fat fryers are usually configured to provide protection for frying pan, drip plate, air filters, takeout conveyor, and the vertical ducts.
The primary goal is to effectively mitigate damage due to fire and smoke within the protected spaces, as well as minimize water damage from a discharge. The system is often a deluge type, releasing from all spray heads of each protected section simultaneously when the section valves are opened.
HI-FOG® also has specially designed spray heads to protect ducts. The spray heads are kept protected outside the duct when not in use, preventing clogging of the nozzle openings.
The entire system is served from a single pump unit, which can be electric or diesel driven. The pump size varies depending on the required protection time and size of the protected area.
System discharge can be activated either manually or through a detection system. The detection system consists of heat detectors, flame detectors, along with a control panel.
HI-FOG® systems for industrial ovens are configured to protect the spaces above and below the conveyor. As with oil cookers, the primary goal is to effectively mitigate damage due to fire and smoke within the protected spaces, as well as minimize water damage from a discharge.
The system is designed for automatic or manual activation of the spray heads simultaneously. Every system has a minimum designed operation time of 30 minutes as required by the NFPA750 standard. However, operation time can be extended as long as there is water and electricity available.
Each system is served by an electric or diesel driven pump unit. The spray heads are mounted both above and below the oven. The system is supplied with a detection system consisting of heat detectors, flame detectors, along with a control panel.
Due to the high temperatures associated with the oven, HI-FOG® tubing and spray heads usually need to be changed twice per year order to maintain material corrosion resistance.
