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 easily 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 hot zone is equipped with HT grade molybdenum elements and radiation shields for long-term reliability. The double-walled stainless steel chamber provides hot zone 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 a 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.
