If you’d like more information or guidance specifying your restaurant project, our dedicated team is committed to tailoring an R-102 system that meets your needs. Contact a Johnson Controls representative to learn more.
With liquid grease filled at least 75mm from the top, the deep fat fryer ignites and burns freely for two minutes with the heat source on. After actuation, R-102 needed to hold extinguishment decrease grease temperature and pass splash tests to pass EN 17446.
On sheet metal at least 2 mm thick, approximately 6 mm of oil was heated until auto-ignition. Following full surface flames, 60 seconds had to pass after free-burn, then the heat source was disconnected, and the R-102 actuation sequence began.
A liquid grease fire 25mm deep in a cast iron skillet was allowed to burn freely at maximum intensity for two minutes on a burner location determined most difficult to achieve extinguishment. To pass the range test, R-102 had to extinguish the flames and not allow re-ignition of the grease for 20 minutes.
With liquid grease 100mm deep in a stainless steel pot, the appliance was heated at maximum intensity. After both auto-ignition and grease temperature exceeded 363 C, the fire continued to burn for two minutes until R-102 was manually actuated.
Low-quality fatty beef steaks are placed on a thick plastic sheet with 6 mm of semi-solid grease. After flames are at least 600 mm high, the fire burns for one minute. Among the requirements for EN 17446, the system must immediately lower the flame and then has one minute to extinguish the fire.
