Why Choose L&L Industrial Box Furnaces?

L&L Special Furnace industrial box furnaces are a cut above the competition because we go the extra mile to do things that other furnace companies do not.

Our goal is to provide our customers with a variety of quality-critical features, from our sturdy exteriors to our robust, easy-to-maintain heating elements. We understand that our customers' needs can change throughout the lifetime of their furnace. With these needs in mind, L&L not only focuses on features such as uniform heating and precise temperature control, but we pay careful attention to maintenance issues, as well. The result is an industrial box furnace that isn't just a good fit on day one, but extends throughout the furnace's useful life. Easy to use, easy to maintain, dependable, and precise are just a few of the words we hear from our customers time and time again when describing our furnaces in general and our industrial box furnaces in particular.

Sturdy Yet Attractive Exterior

Easy to Maintain Refractory Panels

Quality Insulation

Precision, Dependable Temperature Control

Fast Heat Up and Cool Down

Element System

We also use ceramic element terminal blocks that allow the element ends to be clamped without twisting the whole end around a terminal bolt, making it easy to remove an element. In fact, an element in an L&L furnace can usually be changed in less than 5 minutes. Also, the connection wires can be easily removed without disturbing the element termination. This design also allows you to isolate an element for a resistance check very quickly. In addition, L&L's proprietary element terminal block features sturdy element posts with excellent electrical isolation characteristics.

Element Placement

XLE Series Furnace

There are many models that are available in various sizes. While we offer standard configurations, each furnace in the XLE series has an entirely customizable feature list. This list includes options such as different hearth configurations, multiple heating zones, fans, cooling devices, door configurations, inert atmosphere control, racks, baskets, and loading devices. You can view some of our XLE options here. At L&L, our technical sales team will work with you to configure a box furnace to suit your specific heat treatment needs.

Note that we also offer a three-day, all-inclusive startup service as an option with each system within the continental US and Canada. For international customers, startup and training service is available by factory quote. All of our furnaces come with extensive instructions and documentation, also.

XLE Series Applications

L&L services many markets and industries, including aerospace, medical, automotive, research and development, technical ceramics, and other fields. In addition, L&L’s XLE furnaces are all available with a pyrometry package for specialized aerospace, automotive and medical applications. This allows the furnace to conform to AMS2750E and soon-to-be-certified MedAccred guidelines, as well as many other pyrometry specifications.
