The LJ Wing company was founded in 1875 and was a pioneer in the development of specialized fan systems. In 1917 LJ Wing started down the road of providing steam heating solutions for commercial, industrial, and institutional buildings. The experience gained in those early days led to the development of the LJ Wing Integral Face and Bypass (IFB) steam heating coil for air handlers. This combination of a steam heating coil and a powered damper allowed the coil to maintain full steam flow at all times...thus providing freeze protection to the coil while still modulating the leaving air temperature without the need for modulating steam valves. Wing IFB coils are available in vertical (VIFB) or horizontal (IFB) configurations to match the aspect ratio of most air handlers. VIFB coils can be designed for air handlers up to 77,000 cfm. IFB coils can be designed for air handlers up to 50,000 cfm. Special air distribution accessories and units with integrated fans are also available.
Freeze Resistant Coils
LJ Wing has been a leader in providing freeze resistant steam and hot water coils for decades. The University of Michigan is an example of one of the dozens of universities that have relied on LJ Wing Integral Face & Bypass coils over the years
Independently Laboratory Tested
When you specify or purchase a piece of industrial equipment it is important to feel confident that the equipment will perform as expected. This is probably even more important when you are trying to maintain proper conditions in a laboratory, hospital, or food processing facility. The LJ Wing Integral Face and Bypass coil design is the only one of its type that is not simply “tested in accordance with” a standard but is certified to meet the conditions presented in the selection software. Every year ARI randomly selects samples of LJ Wing coils straight from the assembly line and sends them to independent laboratories for testing and verification of performance. ARI Standard 410 clearly defines both the test procedures and the requirements for achieving certification. You can trust LJ Wing to satisfy your requirements.
