L&L Special Furnace Co., Inc. has delivered a high-uniformity box furnace to a worldwide, leading valve manufacturer located in the southeastern United States.
The L&L model XLE 244 is a front-loading, refractory-lined box furnace and has an effective work zone of 22” wide by 22” high by 20” deep. There is a horizontal double-pivoted door with a safety power cutoff switch. A ceramic hearth and standoffs are provided as a workspace.
The XLE 244 is equipped with solid-state relays for fast, quiet cycle times to offer good control. These are housed in a NEMA 1 control panel with single-point power connection. All required fusing and interconnections are included.
The control system is driven by a Honeywell program control with an overtemperature control to prevent the furnace from overfiring. A digital round single-input chart recorder keeps accurate recordings of the furnace process temperature. The Kanthal Iron Aluminum Chrome coiled elements located on the sides, back, and door are controlled in two zones for balancing of temperature gradients from top to bottom.
All L&L furnaces can be configured with various options and be specifically tailored to meet thermal needs. It also offers furnaces equipped with pyrometry packages to meet the latest revision of ASM2750.
Options include a variety of control and recorder configurations. A three-day, all-inclusive startup service is included with each system within the continental U.S. and Canada. International startup and training service is available by factory quote.
