HTF SP SC High temperature split tube furnace
Hobersal’s new HTF SP SC design split tubular furnace, versatile and compact up to 1600ºC heated by Kanthal SiC

The new HTF SP SC series are tube furnaces with a new modern, compact and versatile design with maximum temperatures up to 1600ºC, heated by Silicon Carbide (SiC) Kanthal heating elements and high quality and high density thermal insulation that allow high heating rates and low energy consumption
In addition, thanks to the new design, it is possible to work in a vertical operation adding a vertical operation kit.
HTF SP SC high temperature tube furnaces let work in oxidizing atmosphere, inert or reduced atmosphere and vacuum with our gas and vacuum packages.
