Description
1100°C Vacuum Atmosphere Lifting Furnace with Water Tank Dust Collection and Filtration + VOC Exhaust Gas Purification
The 1100°C vacuum atmosphere lifting furnace is an industrial-grade high-temperature furnace specifically designed for large workpieces, high-temperature sintering, heat treatment, and material research and development. The equipment adopts a bottom-lifting loading platform, enabling automatic lifting and unloading of workpieces, significantly reducing manual labor intensity and improving loading and unloading efficiency.
The entire machine integrates a vacuum system, atmosphere protection system, water cooling system, PLC intelligent control system, water tank dust collection and filtration system, and VOC exhaust gas purification system. It can complete sintering, annealing, heat treatment, and material testing under vacuum or protective atmosphere conditions, while effectively treating dust and volatile organic compounds (VOCs) generated during production, meeting the environmental protection requirements of modern laboratories and industries.
The furnace features a high-purity alumina lightweight lining, a multi-layer energy-saving insulation structure, and a four-sided + bottom composite heating design, resulting in more uniform furnace temperature and stable and reliable long-term operation.
Product Features
- Extra-large furnace chamber, excellent batch processing capacity
The furnace chamber dimensions are 2000mm (L) × 1000mm (W) × 1000mm (H), with a volume of 2 cubic meters. Combined with a lifting loading platform design, it is suitable for vacuum/atmosphere sintering of large batches of materials or large-sized workpieces.
- Water tank dust removal and filtration + VOC exhaust gas purification, clean emissions
Equipped with a water tank dust removal and filtration device, it effectively captures and removes particulate matter generated during heat treatment. The VOC exhaust gas purification system catalytically decomposes organic waste gas into carbon dioxide and water, achieving clean emissions. It meets environmental protection requirements and is suitable for the debinding and sintering process of materials containing binders or organic matter.
- Bottom and perimeter heating of the loading platform, uniform material heating
Utilizing a three-dimensional heating layout of perimeter and bottom, with high-temperature alloy resistance wires arranged at the bottom of the loading platform, the material is heated simultaneously from the bottom and all sides, significantly improving temperature uniformity. Furnace temperature uniformity is ±5℃, and temperature control accuracy is ±1℃.
- Bottom Vertical Lifting + Four-Screw Lifting: Stable and Precise
The charging platform and furnace opening utilize a 3-4 layer tapered stepped soft seal, with elastic high-temperature sealing strips on the steps to effectively absorb thermal expansion. The charging platform is lifted using four screws with adjustable lifting speed. Infeed and discharge are achieved through electric screw mechanical transmission, ensuring good stability and high precision.

Equipped with a 10-inch true color touchscreen PLC centralized control, enabling functions such as temperature setting, historical data recording, and data reporting. Data can be downloaded to a computer for printing, meeting quality traceability requirements.
- Dual-Use Vacuum and Atmosphere Functions with Overpressure Protection
Vacuum level -0.1 MPa, compatible with various gases including hydrogen, nitrogen, argon, carbon monoxide, and oxygen. The overpressure protection system, driven by an electric contact pressure gauge or pressure sensor, automatically closes the inlet valve, activates the exhaust valve, and triggers the alarm.
