A new line of high temperature box furnaces (HS series) is now available from Lucifer Furnaces, Inc. The furnaces are designed for 2450°F operation with silicon carbide heating elements controlled off the line with an SCR power supply. According to the company, the SCR automatically compensates for changes in element resistance and proportions the lowest power input, providing a steady state control. This control package reportedly simplifies furnace operation by eliminating the manual adjustment of tap switches and saves money on initial purchase by replacing the large power transformer, selector switches and oversized contactors.
