PRODUCT PARAMETERS
Description
900°C Box-Type Resistance Furnace XL (Top-mounted Exhaust Gas Purification Device)
The box-type resistance furnace is a high-temperature electric furnace that integrates heat treatment and exhaust gas purification. The equipment adopts a three-zone independent heating design, with high-temperature alloy resistance wires evenly distributed around the furnace chamber and at the bottom. Combined with a top-mounted stirring fan circulation system, this effectively improves the temperature uniformity within the furnace. An exhaust gas purification device is installed at the top of the furnace, using high-temperature oxidation decomposition technology to convert VOCs (volatile organic compounds) into carbon dioxide and water, significantly reducing the environmental impact of exhaust gas emissions.
Product Features
- Top-mounted exhaust gas purification device for high VOC treatment efficiency
The furnace is equipped with an exhaust gas purification device at the top, heating organic waste gas to over 760℃, oxidizing and decomposing VOCs in the waste gas into carbon dioxide and water, achieving clean emissions. This effectively solves the problem of organic waste gas pollution generated during the heating process of samples containing binders, meeting environmental protection requirements.
- Three-zone independent temperature control for excellent temperature uniformity
It features three independent temperature zones: bottom + front + back + left and right, and a three-dimensional heating layout around the perimeter and bottom. Furnace temperature uniformity is ±5℃, and temperature control accuracy is ±1℃, ensuring uniform temperature distribution within the large 850×750×750mm furnace.
- Stirring fan + frequency converter + water cooling
A top-mounted stirring fan, combined with a frequency converter to control its speed, and water cooling to protect the fan motor, forces the circulation of hot air within the furnace, eliminating temperature stratification and dead zones, further improving temperature uniformity.
- Bottom-mounted rapid cooling
Equipped with a 60W blower at the bottom, operating at full power below 520℃, and every 30 seconds for temperatures above 520℃, continuing at full power after the heat preservation period. This accelerates furnace cooling, shortens the process cycle, and improves equipment utilization.
- 50-segment programmable temperature control, 7-inch touchscreen operation
Features 50-segment programmable temperature control, allowing input and setting of multiple temperature rise curves (single 50-segment/two 28-segment/three 15-segment/five 9-segment), which can be recalled at any time. The 7-inch touchscreen features a Chinese menu and can store multiple process curves, historical curves, and data reports, providing intuitive and convenient operation.
