It supports long-term operation at 1100℃. High-temperature alloy resistance wires are distributed around the furnace chamber, with an adjustable heating rate ranging from 1℃/h to 40℃/min. It is equipped with a side-opening and rotatable furnace door, water cooling circulation, and pressure protection. The furnace body is corrosion-resistant and easy to clean, making it suitable for high-temperature sintering and heating needs in scientific research and industrial fields.

| Heating Rate | Freely adjustable. Range: Maximum 40℃/min; Minimum 1℃/h |
| Heating Element | High-temperature alloy resistance wire |
| Heating Element Installation & Replacement | The sealed upper cover of the vacuum atmosphere furnace is equipped with a mechanical lifting mechanism, which allows the sealed upper cover to be lifted easily. After lifting, the entire upper cover can be rotated, saving significant labor and time. |
| Furnace Body | Processed by CNC machine tools, with surface treatments including polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It features a two-color design, novel and attractive appearance, and advantages of oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Body Structure | Double-layer air-cooled structure, ensuring a good working environment |
| Furnace Door Opening Method | Axial 180° side-opening; the furnace door can rotate 300°, preventing the inner wall of the door from scalding the arm when taking materials at high temperatures. |
| Water Cooling | To save resources, the electric furnace is equipped with an imported hot water circulation pump and a circulation water tank. The imported hot water circulation pump can withstand hot water up to 160℃ and operate continuously for more than 1 year. |
| Water-Cooled Parts | Furnace mouth, furnace door, and furnace top of the inner furnace shell |
| Circulating Water Radiator | Multi-channel pure aluminum water circulation radiating fins, which greatly reduce excessive water temperature. |
| Vacuum Pump & Vacuum Degree | Water circulation vacuum pump unit; Vacuum degree: -0.1MPa (indicated by pointer pressure gauge) |
| Pressure Resistance | The furnace chamber steel plate is 6-20mm thick, with double-sided welding, capable of withstanding positive pressure of 0.1MPa |
| Gas Path Valves | Imported stainless steel valves |
| Pressure Detection | 1 pointer pressure gauge with dual indication (positive pressure & negative pressure) (digital vacuum gauge optional, etc.) |
| Pressure Control | Digital vacuum gauge is adopted to realize precise control of vacuum pressure |
| Gas Flow Meter | 2 float flowmeters (digital mass flowmeter optional if higher accuracy is required by the customer) |
| Pressure Protection | Designed to prevent hazards caused by closed exhaust port, blocked exhaust port, or excessive furnace chamber pressure. Principle: Signals are obtained by a pressure contact gauge or pressure sensor, which drives the control module to close the electromagnetic intake valve, activate the electromagnetic exhaust valve and alarm. Pressure is released through the exhaust port, and the sound and light alarm buzzer is triggered to ensure the normal operation of the furnace. |
