Product Description
The NACCTF wire wound tube furnaces, like the smaller NACMTF range use a wire element that is wound directly onto a fixed integral ceramic work tube. The NACCTF range offers tube diameters of 65, 75 and 100 mm (inner diameters).
This simple and economical design provides a furnace that can be used without the need to purchase an additional work tube.
However, should vacuum or a modified atmosphere be required, it is necessary to use a separate additional slide-in work tube in order to provide the required length needed to fit end seals. Similarly, in some circumstances a work tube that has different physical or chemical properties to the fixed work tube may be required. The use of an additional slide-in work tube protects the integral work tube and heating element.

FAQs of NACCTF - Wire Wound Single Zone Tube Furnaces:
Q: How does the NACCTF Wire Wound Single Zone Tube Furnace achieve uniform heating?
A: The furnace utilizes advanced Kanthal or Silicon Carbide heating elements wound around a high-grade ceramic fiber insulation. This design ensures even heat distribution throughout the customizable heating zone, guaranteeing consistent results for various laboratory and industrial applications.
Q: What is the process for selecting the right model for my application?
A: Selection is guided by your desired heating zone length (200 mm to 800 mm), compatible tube diameter (25 mm to 100 mm), required temperature (up to 1300C standard, 1500C maximum), and capacity (1 to 20 liters). The furnace can also be configured for semi-automatic or fully automatic operation and customized dimensions to fit your workspace.
Q: When should I choose a model with Silicon Carbide elements over Kanthal?
A: Silicon Carbide heating elements are recommended for processes requiring higher operational temperatures or faster ramp times, up to the furnaces maximum 1500C rating. Kanthal elements are suitable for general laboratory heating needs and offer excellent durability at standard processing temperatures.
Q: Where is the NACCTF Tube Furnace most commonly used?
A: These furnaces are utilized in laboratories, research centers, industrial quality control departments, and manufacturing facilities across India and globally. They are suitable for applications such as material synthesis, thermal testing, and sintering processes that demand high precision and custom configurations.
Q: What safety features are included to protect users and equipment?
A: NACCTF furnaces are outfitted with an over-temperature protection system and a safe cut-off relay. These, alongside the robust high-grade ceramic insulation and digital PID controller, ensure safe operation and prevent damage to both samples and users during prolonged high-temperature usage.
Q: How do I benefit from the programmable digital PID controller?
A: The programmable digital PID controller allows users to set precise temperature profiles, monitor real-time heating conditions, and consistently maintain setpoints with an accuracy of 1C. This facilitates reproducible experiment conditions, enhanced process control, and maximizes productivity with minimal supervision.
