IFLs are an industry standard for the primary calibration laboratories, providing precise temperature uniformity for freeze point cell calibration and blackbody cavities. Another important application is for isothermalizing furnaces for material processing applications. Tube furnaces are commonly used for materials processing such as annealing, sintering, crystal growing, brazing and controlled diffusion to develop new materials. These tube furnaces are typically electrically heated through discrete electrical resistance heating elements. These heating elements have slightly different resistances resulting in temperature non-uniformity inside the furnace cavity. Heat losses through the ends are also a source of non-uniformity. These temperature non-uniformities often result in unfavorable product yields and misleading recipe development results, which can lead to product development delays. Precise temperature control is important for researchers that are developing new materials and thermal processes in energy conversion, nanotechnology and advanced electronics areas.
ACT has built a number of turnkey IFL systems and is well positioned to develop custom applications to your specifications. Our IFL systems have been shown to provide temperature uniformity, stability and repeatability that is unmatched by conventional electrical resistance heated furnaces and ovens. ACT engineers work with leading edge companies on a daily basis to provide thermal management solutions to challenging and often unique applications.
