Fully automatic
Simple operation
8" Dia. X 12" High hotzone
Table top loading
Compact footprint
The HSD Vacuum Furnace was designed to provide reliable, automatic operation for
brazing, degassing and research applications. All vacuum pumps and system components
are fully enclosed within the welded steel frame. The controls provide true "hands-off"
operation including pump-down, heat ramp, dwell time, gas inlet and
cooldown. Temperature cycles are programmable with multiple Ramp/Dwell segments. The system
controller provides convenient start-up and shut-down cycles as well as control of water
flow and process interlocks.
The top loading furnace layout allows load placement through a convenient hinged lid.
The hotzone is equipped with HT grade Molybdenum elements and radiation shields for
long-term reliability. The double wall, stainless steel chamber provides hotzone cooling
without internal water connections. Top mounted electrical connections eliminate debris
induced electrical failures.
A conservatively rated SCR power controller with current limiter, power feedback control
and rugged stepdown transformer provide furnace power control. Internal sheathed
thermocouples provide feedback to the digital temperature programmer with "fail-safe"
overtemperature alarm. A panel mounted chart recorder is included.
