AJ-XL-CXZ Industrial Furnace Series

Standard Equipment

• Tmax：1200℃/1400℃/1800℃
• Thermocouple type K/S/B
• Electric heating elements: High-temperature alloy resistance wire/SIC/MoSi2
• ≤1200°C: 3-sided heating; >1200°C: 2-sided heating. Expandable heating zones available for improved uniformity.
• Furnace Lining is constructed from vacuum-formed high-purity alumina lightweight material (reinforced with alumina hollow ball boards at impact zones—mouth/base) for extreme heat resistance, minimal heat storage, and thermal shock durability (no cracking/spalling).
• Dual shell ventilated housing made of carbon steel for low surface temperature (<45℃) and high stability
• Temperature control accuracy: ±1℃
• Temperature Uniformity: Within ±5°C (varies by chamber dimensions).
• Heating Rate：Adjustable from 40°C per minute (fastest, non-linear) to 1°C per hour (slowest, non-linear).
• Safety Feature: Main heating circuit disconnects automatically when the door opens at high temperatures.
• By integrating PID control with SCR technology, precise temperature control with comprehensive safety protection.
• 50-Segment Temperature Control Program Settings：1 curve = 50 segm0ents；2 curves = 28 segments/curve; 3 curves = 15 segments/curve; 5 curves = 9 segments/curve.
• Housing coated in RAL 7035
• RS485 Communication Interface
• Lead Time：Standard sizes: within 7 days；Customized chamber: 7–15 days
• Warranty：1-year free warranty for the furnace； Bottom plate and heating elements not covered； Heating elements: free replacement within 3 months if damaged naturally.
• Accessories: A pair of crucible tongs and a pair of high-temperature gloves.

• Additional Equipment
• Lift door：Pneumatic door opening, controlled by foot pedal, with hot surface facing away from the operator.
• Touchscreen: Multilingual menu, multiple temperature rise process curve storage, historical curve storage, and data reports (7 inches).
• Computer Control: Controls furnace start, pause, stop, stores historical curves, sets temperature rise curves, reads temperature rise curves, sets parameters, etc.
• Siemens PLC Control: Real-time data reading with open ports for data communication with upstream and downstream equipment.
• Manual or automatic gas supply system
• Observation Window: Designed on the furnace door with high-temperature-resistant quartz glass.
• Movable Casters: Two swivel casters and two fixed casters.
• Rapid Cooling: Achieved with a frequency inverter and centrifugal fan for programmable cooling control.
• Quick Discharge Rack: The material rack is made of high-temperature steel, with wear-resistant heavy-duty refractory bricks on the top, enabling rapid
• transfer of materials from the furnace to an external platform in high-temperature environments.
• Multi-Point Temperature Control: Independent temperature control on multiple sides for improved temperature uniformity.
• High temperature furnace chamber with multi-sided heating for very good temperature uniformity.
• Stirring Fan: Metal stirring fan, can be linked with PLC to automatically start at designated temperature segments.
• Independent Control Cabinet: Separate control cabinet with an extended control cable length (up to 5 meters).
• Heat Storage Furnace Bottom: The furnace bottom sinks 50mm with a hollow design, supported by multiple vertical columns, increasing Ceramic Load-Bearing Plate and ensuring uniform heat distribution at the bottom.
• Exhaust Gas Treatment: Adds VOC exhaust gas treatment furnace with a capacity of 40m³/H or 80m³/H.
• Corrosion-Resistant Furnace Lining: Furnace lining material resistant to acids, alkalis, and hydrofluoric acid corrosion.
• Heating Element Protection: Prevents contamination from powder and corrosion from volatile substances and scratch.
• Clean Furnace Lining: Furnace lining made of ceramics, high-temperature glass, and high-temperature metals to prevent dust and volatile substances.
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Customizable charging racks according to requirements, for loading the furnace in two levels.
