Product Description
The NACMTF wire wound tube furnaces, like the larger diameter CTF range use a wire element that is wound directly onto a fixed integral ceramic work tube.
This simple and economical design provides a furnace which can be used without the need to purchase an accessory work tube.
However, should vacuum or a modified atmosphere be required, it is necessary to use a separate 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 NACMTF - Wire Wound Single Zone Tube Furnaces:
Q: How do I operate and set temperatures on the NACMTF wire wound tube furnace?
A: Operating the NACMTF is straightforward, thanks to its digital PID controller. Simply use the digital display to select your desired setpoint (up to 1200C). The controller maintains precise temperatures and allows for both rapid heating and controlled cooling, ensuring accuracy within 1C.
Q: What tube materials and sizes are compatible with this furnace model?
A: This furnace is compatible with quartz, alumina, and stainless steel tubes. Tube diameters ranging from 1 to 8 inches can be accommodated, making it flexible for various sample sizes and experimental needs.
Q: When should I use natural versus forced air cooling in this furnace?
A: Natural air cooling is suitable for gradual cooldowns, while forced air cooling should be used when faster temperature drops are required or for sensitive materials that need rapid cooling post-processing.
Q: Where can this furnace be installed for optimal performance and safety?
A: Designed as a benchtop unit, the NACMTF should be placed on a stable, heat-resistant laboratory bench in a well-ventilated environment. Ensure adequate clearance for ventilation, especially when using forced air cooling.
Q: What are the primary benefits of the double layer ceramic fibre insulation?
A: The double layer ceramic fibre insulation provides excellent thermal efficiency, minimizing heat loss and ensuring consistent temperatures throughout the heating zone. This enhances energy-saving performance and protects the exterior casing from excessive heat.
Q: What safety features are included with this furnace?
A: The NACMTF is equipped with an over-temperature protection relay, which automatically shuts off power if temperatures exceed the programmed threshold, safeguarding both users and samples against overheating accidents.
