RADIANT TECHNOLOGY CORP.

The TFA-series of infrared furnaces are designed for processes requiring close control of both temperature and atmosphere. Primarily intended for thick film firing of precious metal compositions and air fire-able resistors, these furnaces can also perform many lower temperature processes.  The maximum operating temperature of the system is 1000°C.
The Chamber construction, gas controls, and exhaust are designed to control in-process atmosphere by maintaining equilibrium between input exhaust and leakage.  Typical performance allows furnace induced gaseous contaminants to be held at or below 150 ppm using either oxidizing or inert atmospheres.  For applications requiring lower Oxygen ppm levels such as copper conductor firing, gas tight models are available with operating parameters of <5 ppm Oxygen reference RTC S-Series controlled atmosphere furnaces).
All furnaces in the TFA-series provide a load station, multi-zone infrared heating section, two stage cooling and an unload station. Furnace operation is left to right as viewed from the operator control panel.
