4441 North American Tempest® Metal Tile | Performance Data
The metal tiled 4441 Tempest “MRH/F” and “MRM/F” features 310 Stainless Steel Alloy tiles. The “MRH/F” has the same high velocity (HV) tile exit size as ceramic tiled 4441’s and the “MRM/F” has a medium velocity (MV) tile. Both alloy 4441 tile options use the same body assembly as the standard 4441 Tempests, so use the 4441 Bulletin for general application information. This information sheet is for data specific to the “MRH/F” and “MRM/F” options. While ceramic tiles have superior high temperature resistance, metal tiles burners are more resistant to mechanical damage and the effects of thermal stress. When choosing a tile material consider the operating temperature, burner mounting style, and desired flame geometry.
