Overview for High Temperature Vacuum Heat Treatment Furnace Furnace

Vacuum heat treatment furnace features a sealing chamber with high alumina content fiber insulation and powerful heating elements up to 1600 degree C. We build the vacuum furnace structure with dual steel structure, welded and oil leak tested chamber to ensure air tightness. Dual door design make the chamber sealing condition much better. Max vacuum level reach to 10-5 torr with Diffusion vacuum pump unit. Multiple gas inlets and outlets with stainless steel ball valves. The vacuum furnace provides the perfect heat treatment environment for various procedures in many laboratories, providing the controlled temperature and atmosphere specific projects require.

Main Features

Ramping Dwelling and Cooling Curves for 1700C Heat Treatment Furnace

Safety Measures

• Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
• Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions
• Power failure protection resumes furnace operation right after the point of failure when power is reestablished
• Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Technical Specifications

Application Notes

• However, toxic or explosive gases that may generate from the sample during the heating are not recommended for use with this high temperature muffle furnace without necessary safety controls and supervision.
• Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.
• Ultimate vacuum level for PA Controlled Atmosphere muffle furnace is around 90000 Pa with hose barb connections. Please keep in mind that our PA atmosphere furnaces are NOT designed to be vacuum furnaces, the vacuuming part is mainly for users to pre-vac the chamber, before putting in inert or other protective gases, if you have special request on vacuum level, please order our professional vacuum furnaces
