Product Description

The NACTZF 3-zone high temperature tube furnaces are available at 1500 °C, 1600 °C, 1700 °C and 1800 °C The heated length is divided into 3 zones.

An extended uniform zone in the mid-section of the work tube is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.

Standard Features

1500 °C and 1600 °C models have silicon carbide heating elements
1700 °C and 1800 °C models have molybdenum disilicide heating elements
Accepts work tubes with maximum outer diameters up to 90 mm
Heated lengths of 600 or 610 mm depending on the model
End zone control is via back to back thermocouples (NACTZF 15)
End zone control is via retransmission of set point (NACTZF 16, NACTZF 17 and NACTZF 18)
Carbolite 301 controller, with single ramp to set-point & process timer (NACTZF 15 & NACTZF 16)
Programmable 3216P1 controller (NACTZF 17 & NACTZF 18)
Overtemperature protection (NACTZF 17 & NACTZF 18)

Options (specify these at time of order)

Wide choice of tube diameters and materials is available: eg quartz, ceramic, metal
Over-temperature protection (recommended to protect valuable contents & for unattended operation) (TZF 15 & TZF 16)
Control module with 2 metre conduit to furnace

Precision Through Three-Zone Heating

Each NACTZF furnace offers three distinct heating zones, each approximately 300 mm in length, allowing for optimized and uniform heating along the entire tube. Independent zone control ensures temperature precision, beneficial for complex thermal profiles in research and development applications.

Advanced Programmable Controls

The intuitive digital PID temperature controller enables users to set up at least seven programmable heating segments. This feature facilitates sophisticated heating ramps and hold periods, offering flexibility for a wide range of thermal processes such as sintering, annealing, and controlled crystal growth.

High-Quality Construction and Materials

Constructed with high-grade alumina and stainless steel exterior, the furnace features top-tier molybdenum disilicide or silicon carbide heating elements, durable quartz or alumina tubes (optional), and robust ceramic fiber insulation for high efficiency. Powder coating and over-temperature safeguards reinforce long-term operational safety and reliability.

Versatility for Laboratory Applications

Designed to accommodate tube diameters from 30 mm to 120 mm and operate under inert or reducing atmospheres, the NACTZF furnace supports a wide array of laboratory experiments, including advanced material synthesis and heat treatments. Gas-tight chamber options allow work with sensitive atmospheres.

FAQs of NACTZF - High Temperature 3 Zone Tube Furnaces:

Q: How does the NACTZF furnace maintain uniform temperature across all three zones?

A: The NACTZF furnace utilizes three independently controlled 300 mm zones with high-quality heating elements and ceramic fiber insulation, ensuring uniform heat distribution. The system maintains a temperature consistency of 3C along the tubes length, ideal for processes that demand thermal uniformity.

Q: What processes can be carried out using the NACTZF High Temperature 3 Zone Tube Furnace?

A: This furnace is designed for laboratory-scale high-temperature applications, such as annealing, sintering, material synthesis, and controlled crystal growth. Its precise temperature control and programmable profiles make it suitable for research and industrial development.

Q: When is it necessary to use a protective gas atmosphere with this furnace?

A: You should use an inert or reducing gas environment when processing materials that are sensitive to oxidation or require controlled-atmosphere conditions. The NACTZF supports these atmospheres and offers gas-tight sealing, enabling experiments with sensitive or reactive samples.

Q: Where can the NACTZF tube furnace be installed and used?

A: This model is designed for laboratory use, particularly in research institutes, academic labs, industrial R&D centers, or quality control departments. Its compact dimensions (approximately 1200 x 550 x 650 mm) and robust build make it suitable for benchtop installation in controlled environments.

Q: How does the programmable controller enhance user operation?

A: The PID digital controller allows users to create custom temperature profiles with at least seven steps, including programmable ramps and holding periods. This improves reproducibility, automation, and process optimization, reducing manual intervention during complex thermal cycles.

Q: What are the benefits of choosing the NACTZF furnace for laboratory heating needs?

A: Key benefits include excellent temperature accuracy (1C), reliable temperature uniformity, customizable tube diameter, robust safety features like over-temperature protection, and the flexibility to handle different atmospheres. This adaptability makes it efficient and cost-effective for varied laboratory requirements.

Q: What materials are used in the construction of the NACTZF tube furnace?

A: The furnace is constructed from high-grade alumina and stainless steel for durability, with heating tubes made of optional quartz or alumina. Molybdenum disilicide or silicon carbide heating elements and ceramic fiberboard insulation ensure long life, efficiency, and chemical resilience.
