COMPANION ELECTRIC TEMPERING FURNACE AND QUENCH TANK
Electric Tempering Furnace can
be combined with electric Bench Furnaces or Inert Atmosphere Bench Furnaces to
produce a space-saving, over-and-under, heat treating and tempering furnace combination.
The top chamber with its manually operated vertical lift door can be selected
from among four sizes of 2000°F and 2200°F Bench Furnaces described
on Bulletin BF-710 or Inert Atmosphere Bench Furnaces
described on Bulletin BF-720. The Quench Tank is
a free standing unit available with electric heat.
