Continuous operating temperature is 100°C below maximum temperature. Holding power is measured at the continuous operating
temperature. Uniform length measured with end plugs fitted.
** To ensure tube end temperatures that are compatible with sealing assemblies, worktubes extending beyond the
standard length are required when working with modified atmospheres. Radiation shields may also be required.

A range of tube furnaces offering the higher temperatures that are
available from silicon carbide heating elements, with the additional option
of a vertical ‘L’ stand and separate controller if preferred. The user must
select an accessory worktube specific to their application.
Requires but does not include an appropriate accessory work tube 19.5mm
to either 60mm or 90mm outer diameter

Power Supplies for Silicon Carbide Furnaces
The characteristics of the control systems that
are used with silicon carbide elements result
in maximum power supply requirements that
are not as intuitively derived as those for
furnaces using other heating technologies.
For this reason a more detailed description
of the maximum power supply that is
required per phase has been included in the
specification table.
