L&L Special Furnace Releases A New Four-page Brochure

L&L Special Furnace has released a new four-page brochure describing our line of general purpose electric heat treating furnaces.

Although “standard” configurations are made, each furnace is normally fitted with standard and special options to suit specific needs. These include vertical doors, fans, cooling venturis, vents, special hearths, racks, baskets and loading devices, quenching systems, various controlled atmospheres, retorts, viewing ports, special element alloys, special thermocouples, various kinds of alarms, program controls and recorders.

In 2004 and 2005, NASA purchased two 36-cubic- foot model XLE3648 furnaces used in conjunction with the other equipment to provide R&D mirrors for the Constellation-X space telescope. With this development, NASA discovered that by uniform precise heating, we could control the magnitude and degree of slumping. This laid the foundation for NASA’s ability to meet an extremely high production criteria for the Constellation-X project.

A more recent requirement called for 10 model XLE3648 furnaces supplied in a six to eight week delivery. L&L’s versatile XLE series furnaces have many control options available, including ramp/soak program controls, temperature recorders and SCR power controls. Process accessories such as inert atmosphere blanketing and manual or powered venting add to the versatility of the XLE series furnace.
