What We Do

LCI FurnacePros provides equipment and software upgrades, parts and service for infrared furnaces manufactured by LCI, RTC Radiant Technology Corporation and GreenBridge Technology. With a close understanding of these vigorous production and laboratory furnaces, FurnacePros can offer updated furnce contnrol software installed on a managed platform minitower that can significantly extend the life of existing equipment.  Because of our lean and efficient business model, we can offer the lowest prices anywhere for equipment and parts of the quality necesssary for long life in a production environment.


RTC infrared furnaces are built for production applications that require highly repeatable performance temperature profiles from as low as 80 C up to 1000 C in a controlled atmosphere of nitrogen, forming gas, hydrogen, clean dry air or other process gas. On-board sampling system and analyzers can monitor furnace atmosphere conditions achievable below 10 ppmv oxygen. Residence time, ramp-up and cooling rates are controlled by sophisticated PID software operated on a Windows(tm) based terminal. Equipment is designed for expected life of better than 15 to 20 years.  Carefully engineered upgrades can often substantially extend the life of this equipment.

The electrics on most furnaces are configurable for installation world-wide, so the furnace can be moved from one location to another often with only a simple re-tap of the inputs to accommodate the new environment (for example 480 Vac, 60 Hz to 380 Vac, 50 Hz).


GreenBridge Technology, the original Radiant Technology Corporation, spun off its furnace business, including service and replacement parts support, in March 2007.  For more than 30 years, RTC built itself into the world leader of conveyor near-infrared furnaces, ovens and dryers for the photovoltaic (solar cell), semiconductor processing, and microelectronics packaging and assembly technology industries. Now Lochaber Cornwall Inc (LCI) is responsible for warranty of your continuous belt furnace equipment.


Comprised of former GreenBridge and RTC staff, LCI FurnacePros emerged in March 2007 to continue to supply high quality furnace equipment and service to new customers and customers with RTC furnaces.   Therefore, when FurnacePros provides technical support or parts for your GBT or RTC brand furnace, it is supported by the same team that has accumulated many years of knowledge and experience building conveyor near-infrared furnaces for many applications.


See our new support page for technical notes and installation and troubleshooting documents for getting the most out of your RTC Radiant Technology and LCI FurnacePros infrared furnaces.
