AJ 800°C Industrial Heat Treatment Drying Oven Hot Air Circulation Trolley Furnace

The AJ-XL series 800°C high-temperature drying oven adopts an integrated compact design of the control system and furnace body, as shown in the figure. The furnace chamber uses vacuum-formed high-purity lightweight alumina fiber insulation material.
This equipment uses high-temperature alloy resistance wire heating elements and is specially designed and manufactured for university laboratories, research institutes, and industrial enterprises. It is widely used in the sintering, melting, analysis, and production processes of ceramics, metallurgy, electronics, glass, chemical materials, machinery, refractory materials, new materials, special materials, building materials, metals, non-metals, and various composite materials.
The control panel is equipped with an intelligent temperature controller, power switch, main heating start/stop button, voltmeter, ammeter, and computer communication interface, enabling real-time monitoring of the system's operating status. The equipment adopts a reliable integrated circuit design and offers excellent working stability and anti-interference performance. Even at the maximum operating temperature, the outer surface temperature of the furnace body remains ≤45°C, significantly improving the working environment.
The equipment uses microcomputer PID program control with programmable heating curves, achieving fully automatic heating and cooling cycles. Temperature parameters and programs can be modified during operation, providing flexible adjustment and convenient operation.
Temperature control accuracy: ±1°C, without overshoot
Constant temperature accuracy: ±1°C
Maximum heating rate: ≤20°C/min
The furnace lining is entirely made of vacuum-formed high-purity lightweight alumina fiber material, featuring high service temperature, low heat storage capacity, excellent thermal shock resistance, and good insulation performance. Its energy-saving effect is more than 60% higher than that of traditional electric furnaces.
The equipment has a reasonable structural design, adopting a double-layer furnace shell and an air-cooled heat dissipation system, which can greatly shorten the experimental and production cycles.
