SPECIAL 4441 INFORMATION
Besides the standard options listed above, 4441 Tempest® burner are available in many other special configurations.
Hot Air: Most 4441 configurations can be built with special components for use with preheated air to 800°F (427°C)
Medium velocity tiles: Many 4441 configurations can be assembled with tiles larger exists to deliver lower flame velocities. —These sizes can be special ordered with a one size larger tile exit: -1,-2,-3,-4-A, -5, -6, -8-A, -8-B —These sizes can be special ordered with two sizes larger tile exit: -1, -2, -3, -5, -8-A
Extra high velocity Tempest® tiles: Many 4441 configurations can be assembled with tiles with smaller exists to deliver even higher flame velocities. These sizes can be special ordered with a one size smaller tile exit: -2, -3, -4-A, -4-B, -6, -7, -8-B, -8-C
Special tile mounting plates: 4441 burners can be engineered with special mounting plates, for example: —Built in connections for LNI low NOx injectors —Custom tile mounting plates to match existing burner mounting configurations
All 4441 burners come with a direct spark igniter, an optional pilot tip is available for 4441-8 sizes.
