Vacuum Tilting Rotary Tube Furnace

Applications: Widely used in powder, ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials and other fields.

• Stainless steel KF metal flange sealing (double O-rings)
• Furnace body temperature near room temperature
• Dual-circuit protection
• Excellent thermal insulation performance, high temperature resistance
• Vacuum degree: -0.1MPa
• Compatible with multiple gases (oxygen, nitrogen, argon, hydrogen, etc.)

Gas Control Cabinet Specifications
⦁    Gas Supply Types: 2 standard (expandable to 1-10 types)
⦁    Gas Mixing: Adjustable via individual flow meters
⦁    Valves: Imported stainless steel valves (options: standard, SS, or solenoid valves)
⦁    Flow Meters: Two 0-300 mL/min (optional: mass flow meters, float-type flow meters, etc.)
⦁    Pressure Monitoring: Dual-range gauge (positive/negative pressure) (optional: digital vacuum gauge)
⦁    Vacuum Pump: Dual-stage rotary vane pump (2 L/min pumping speed)
⦁    Gas Lines: Dedicated PV tubing (optional: clean stainless steel piping for high-purity gases)
⦁    Pressure Protection：To avoid hazards caused by closed furnace tube exhaust ports, blocked exhaust ports, or excessive furnace tube pressure, this system is specially designed. Principle: The electrical contact pressure gauge or pressure sensor obtains signals to drive the control module to close the electromagnetic intake valve, activate the electromagnetic exhaust valve and alarm. Thereby protecting the normal operation of the electric furnace.
⦁    Gas Leakage Alarm：According to the atmosphere used, to avoid leakage; Function: When the gas leakage alarm detects that the content of harmful or hazardous gases in the (indoor) air exceeds a certain level, the drive module shuts down the furnace, closes the gas supply intake, opens the exhaust port and ventilation, etc., thereby achieving a good working environment.

Additional Equipment
