Intelligent Muffle Furnace Max.Temp 3092°F(1700℃) Lab Intelligent High-Temperature Box-Type Vacuum Atmosphere Furnace 0-20℃/min Heating Rate AC110V 4KW

Product Overview The Intelligent High-Temperature Vacuum Atmosphere Muffle Furnace features smart temperature control, multi-atmosphere compatibility, and high-efficiency safety. The furnace employs pre-vacuum pumping to minimize oxygen content, followed by inert gas (N2/Ar) infusion, creating an ideal controlled-atmosphere thermal environment. With temperature control accuracy of ±1℃, rapid heating (≤20℃/min), and energy-saving design, its high-purity alumina fiber chamber enables applications in material science (ceramic sintering, metallurgy), chemical synthesis, and ash testing. Widely adopted in research institutes, university labs, and small-batch industrial precision processing.

• Precision vacuum & gas control -- Equipped with a vacuum pressure gauge for real-time monitoring of furnace chamber vacuum levels, and integrates a float-type flow meter for visual adjustment of gas flow rates. The inlet/outlet valves support multi-gas switching (including hydrogen <5%, argon, nitrogen, etc.), ensuring safe gas replacement during high-temperature operations.
• Energy-efficient insulation material -- The furnace utilizes advanced lightweight alumina polycrystalline fiber, offering excellent thermal insulation, high-temperature resistance, and rapid thermal cycling capability. This material ensures no unwanted interaction with processed products while achieving 60%-80% energy savings compared to conventional electric furnaces
• Smart multi-function control panel -- The control panel integrates multiple functions, including temperature controller, ammeter, voltmeter, turn-on, turn-off, power indicator, open circuit indicator, and more. It features a intelligent LCD display with clear data visualization and user-friendly operation.
• Secure heat-resistant door design -- The robust double-layer thickened steel plate door design effectively minimizes heat transfer, maintaining a safe external surface temperature even at high operational temperatures. Four handwheel locking mechanisms ensure stable pressure support during vacuum pumping or gas charging processes, preventing any deformation of the furnace structure.
• Superior sealing & easy operation -- The furnace door also features an integrally milled flat surface with pre-embedded silicone sealing strips, delivering exceptional sealing performance and atmosphere control stability. Its user-friendly opening/closing design successfully balances the stringent sealing requirements of industrial equipment with the operational convenience demanded in laboratory settings.
