Advanced Precision and Control

Equipped with a PID microprocessor-based temperature controller, the NACHVTT High Vacuum Tube Furnace delivers excellent temperature stability and control. The digital display has a fine resolution of 0.1C, ensuring precise monitoring throughout every process. The furnace accommodates various thermocouple types (B, S, or K), allowing users flexibility depending on their accuracy needs and temperature requirements.

Robust Design for High Demands

Crafted from powder-coated mild steel and insulated with ceramic fiber blanket, this furnace boasts durability and energy efficiency. Its forced air cooling system maintains operational safety and prolongs component life. Turbo molecular pump integration supports high-vacuum operations, essential for advanced material synthesis and research activities.

Ease of Use and Safety Assurance

User safety and convenience are prioritized with features like over-temperature protection, emergency stop, and user-friendly interfaces. Data logging capabilities via USB or RS-232 facilitate easy monitoring and compliance. Its semi-automatic operation suits both routine and specialized applications across laboratories and industries in India and abroad.

FAQs of NACHVTT - High Vacuum Tube Furnaces :

Q: How does the NACHVTT High Vacuum Tube Furnace achieve high-vacuum conditions during operation?

A: The furnace uses a turbo molecular pump-supported vacuum system to reach and maintain working pressures below 10 mbar, essential for processes requiring minimal atmospheric interference, such as material synthesis and sintering.

Q: What types of heating elements are available, and how do they benefit different applications?

A: The NACHVTT furnace is compatible with Kanthal/A1 and MoSi2 heating elements. Kanthal/A1 is ideal for general-purpose heating, while MoSi2 is preferred for higher temperature stability and longevity, allowing users to match their heating requirements for processes like annealing or heat treatment.

Q: When should I use the emergency stop or over-temperature protection features?

A: The emergency stop should be pressed immediately in any unsafe or abnormal operational situation. Over-temperature protection automatically engages to prevent overheating, protecting both the sample and equipment from potential damage.

Q: Where can this furnace be effectively utilized?

A: This furnace is suitable for laboratory and industrial environments, serving applications in material research, quality control labs, and manufacturing sectors that demand high-precision heat treatment and vacuum processing.

Q: What is the process for data logging and how is it accessed?

A: The furnace allows for real-time data logging of temperature and operational parameters via USB or RS-232 interfaces. This feature enables users to monitor, record, and analyze their experiments or production runs efficiently.

Q: How does forced air cooling benefit the operation of the furnace?

A: Forced air cooling enhances operational safety by preventing overheating of the furnace shell and internal components, extends equipment lifespan, and ensures stable performance even during prolonged use.

Q: What are the main benefits of using a PID microprocessor-based temperature controller with this system?

A: The PID microprocessor ensures highly accurate and stable temperature control, minimizing fluctuations to within 1C. This precision is crucial for research and industrial applications demanding repeatable, reliable thermal conditions.
