It can achieve positive and negative pressure regulation and multi-atmosphere control, making it a highly safe and stable hydrogen furnace/atmosphere furnace widely used in scientific research and industrial production.
Caractéristiques du produit
- Integrated Design, Fully Functional
This equipment integrates a temperature control system, vacuum metal furnace chamber, vacuum pump, gas circuit, pressure protection, gas flow control, positive and negative pressure display, and water circulation pump into one unit. The water circulation tank and furnace body are separate structures.
- Mechanical Lifting of Sealed Top Cover
The vacuum atmosphere furnace’s sealed top cover is designed with a mechanical lifting mechanism, allowing for easy lifting of the sealed top cover. After lifting, the entire top cover can rotate, saving manpower and time. Heating elements are easy to install or replace, and maintenance is simple.
- Vacuum and Multi-Atmosphere Compatibility
It can accept various gases such as hydrogen, nitrogen, argon, carbon monoxide, and oxygen. It uses a two-stage direct rotary vane vacuum pump, achieving a vacuum value of -0.1 MPa. Equipped with dual-indicator pressure gauges for positive and negative pressure, a digital vacuum gauge is optional.
- Precise Pressure Protection System
To prevent hazards caused by closed or blocked furnace exhaust ports, or excessive furnace pressure, a dedicated pressure protection system is installed. Signals from an electrical contact pressure gauge or pressure sensor drive the control module to close the electromagnetic inlet valve, activate the electromagnetic exhaust valve and alarm, releasing pressure from the exhaust port. An audible and visual alarm buzzer sounds, protecting the electric furnace for safe operation.
- 7-Contrôle centralisé à écran tactile de 10 pouces
A 7-inch touchscreen is used for centralized control of the heat treatment process of non-ferrous metal tungsten and molybdenum materials in a hydrogen atmosphere. The temperature controller employs high-precision 50-segment temperature control and can store multiple sintering curves.

| Pressure Protection | System designed to prevent dangers caused by closed exhaust port, blocked exhaust port, or excessive furnace pressure. Principle: Signal obtained from electric contact pressure gauge or pressure sensor drives the control module to close the electromagnetic intake valve, activate the electromagnetic exhaust valve and alarm, releasing pressure from the exhaust port, with audible and visual alarm buzzer sounding, thus protecting the normal operation of the furnace. |
| Gas Leakage Alarm | Avoids leakage based on the gas atmosphere used. Function: When the gas leakage alarm detects that the content of toxic, dangerous or other gases in the air (indoors) exceeds a certain value, the drive module shuts down the furnace, closes the gas supply, opens the exhaust port and exhaust fan, etc., thereby achieving a higher and safer working environment (customer optional). |
| Compatible Atmospheres | Hydrogen, nitrogen, argon, carbon monoxide, oxygen, etc.. |
| Matériau réfractaire | Furnace lining made of vacuum-formed high-purity alumina lightweight material.

| Control | Closed-loop technology thyristor module trigger control, phase-shift trigger control or zero-crossing trigger mode. Output voltage, current or power continuously adjustable with constant voltage, constant current or constant power characteristics. Current loop is inner loop, voltage loop is outer loop. When sudden load is applied or load current exceeds the current limit value, the regulator output current is limited within the rated current range to ensure normal operation of output and regulator. Meanwhile, the voltage loop also participates in regulation, limiting the regulator output current within the rated current range, maintaining constant output current and voltage with sufficient adjustment margin. This protects heating elements from excessive current and voltage surges, achieving safe and reliable control and control accuracy. |
