Advanced Corrosion Resistance

  • Alumina Chamber Design
    High-purity alumina chamber ensures excellent corrosion resistance for halides, fluorides, and aggressive materials.
  • SiC Heating with Alumina Tube Protection
    Silicon carbide heating rods are fully encased in alumina protection tubes, preventing direct contact with vapors and particles.

This anti-corrosion vacuum atmosphere furnace is specifically designed for aggressive or reactive material processing at high temperatures.Ideal for battery materials, halide-based compounds, solid-state electrolytes, and R&D applications requiring both high temperature and chemical resistance.


Technical Specification

Power Supply: AC 380V
Rated Operating Temperature: 1250°C
Long-Term Operating Temperature: 1200°C
Control Range: 50°C to 1200°C
Temperature Sensor: K-type thermocouple (0–1320°C range)

Heating Element Configuration:

  • U-shaped silicon carbide (SiC) rods mounted on both sides, protected by alumina tubes. 
  • SiC rods are made from high-purity α-SiC, offering fast heating, high thermal efficiency, long lifespan, and resistance to deformation at high temperatures (up to 1500°C).

Furnace Body:

  • CNC-machined, polished, acid-washed, phosphated, and powder-coated for durability.
  • Dual-color design with anti-oxidation, acid/alkali resistance, and high-temperature stability.
  • Double-layer air-cooled structure ensures safe operation.

Door Mechanism:

  • 180° side-hinged opening to prevent arm exposure to high temperatures during loading/unloading.

Cooling System:

  • Equipped with imported high-temperature water circulation pump (160°C resistant) and 304 stainless steel reservoir (150–200L capacity).
  • Water-cooled sections: furnace mouth, door, and top.
  • Multi-channel aluminum heat sink for efficient cooling.

Vacuum System:

  • Dual-stage rotary vane vacuum pump with a vacuum range of -0.1 MPa (pointer gauge).

Pressure Resistance:

  • 6–20 mm thick steel shell with double-sided welding, withstands ±0.1 MPa pressure.

Gas Control:

  • Imported stainless steel valves, dual ball flow meters (upgradable to digital mass flow meters).
  • Pressure protection: Electromechanical pressure sensor triggers alarms and vents excess pressure.
  • Optional gas leak detection (H₂, N₂, Ar, CO, O₂, etc.) with automatic shutdown.

Refractory & Insulation:

  • High-purity alumina lining.
  • Triple-layer insulation: alumina silicate board + alumina fiber board + polycrystalline alumina fiber board.
  • Exterior temperature remains below 45°C during continuous operation.

Safety & Controls:

  • Integrated module with dual-loop protection (overcurrent, phase loss, overvoltage, thermocouple failure, etc.).
  • SCR-based closed-loop control with soft-start, constant voltage/current/power modes.

Display & Interface:

  • Real-time monitoring: temperature, segment time, power output, voltage, current.
  • High-durability LED-backlit buttons (100,000+ cycles).

Programmable Curves:

  • 30-segment (expandable to 50) PID/APID/MPT control with self-tuning.
  • Supports multi-curve input and slope-adjustable ramping (40°C/min max; 1°C/h min).

Communication:

  • RS485 interface (1200 m range) for PC remote control, data logging, and curve editing.

Included Accessories:

  • 2 SiC heating rods, fixtures, furnace door insulation plug (for ≥1200°C models), crucible tongs, high-temperature gloves.

Warranty:

  • 1 year for furnace; 3 months for heating elements.

Optional Upgrades:

  1. Crucibles, setters, alumina/SiC trays.
  2. PC control software/hardware.
  3. Touchscreen temperature controller.

Usage Notes:

  • Recommended ramp rate: 10–20°C/min to prolong element life.
  • Minor furnace cracks over time are normal (repairable with alumina coating).
  • Avoid liquid spills; use trays or alumina powder as barriers.
  • Install in well-ventilated, dry areas.

Packaging & Shipping:

  • Triple-layer packaging (foam wrap + plastic film + wooden crate).
  • Free domestic door-to-door delivery (urban areas).
  • Damage coverage during transit.
  • Logistics: Road/rail/sea/air freight; dedicated vehicles for nearby deliveries.
