Product Description

The NACTVS tube furnaces use free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters.

These furnaces comprise a furnace body which is hinged and split into two halves along its length. This makes exchange of work tubes easier and also enables the furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace difficult. This design is particularly suitable for incorporation into extension test and creep test apparatus.

This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application eg for use with modified atmosphere or vacuum.

The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination. The near-hinge format is standard, an alternative option that can be specified at the time of purchase is the far-hinge format, where the pivot of hinges is further from the centre line of the furnace to enable a wider opening action. A horizontal equivalent of the NACTVS range, the NACHZS range is available.

Optimised Three-Zone Heating

Each zone of the furnace offers independent PID temperature control, ensuring exceptional temperature uniformity and ramp rates from 0.1C/min to 30C/min. This level of control enhances results in applications like sintering, heat treatment, and advanced material development.

Safety-Centric Build

The furnace incorporates essential safety features such as over-temperature alarms, a door interlock mechanism, and fuse protection. These additions are aimed at safeguarding both the user and the equipment during high-temperature operations, making it suitable for regulated laboratory environments.

Versatile and Durable Construction

Compatible with a variety of tube materials, including quartz, alumina, and ceramics, the NACTVS-VSTF-3Z is well-suited for versatile research needs. Its mild steel body with powder-coated finish and high-density ceramic fibre insulation mean its built for both durability and reliable thermal efficiency.

FAQs of NACTVS - Vertical Split 3 Zone Tube Furnaces:

Q: How do I operate the NACTVS Vertical Split 3 Zone Tube Furnace for optimal temperature uniformity?

A: To achieve optimal temperature uniformity, use the digital PID temperature controller to independently set and monitor each zone. Adjust the heating rate (from 0.1C/min to 30C/min) as needed, ensuring uniform heating throughout the tubes length. Always confirm your set points on the digital display before starting the process.

Q: What types of tubes are compatible with this furnace?

A: The furnace supports tubes up to 80 mm in diameter made from quartz, alumina, or ceramic. Ensure the selected tube is compatible with the intended process temperature (up to 1600C) for best results and safety.

Q: When should the safety features be checked or used?

A: Safety mechanismssuch as the over-temperature alarm, door interlock, and fuse protectionoperate automatically. However, you should inspect their functionality during regular maintenance or before extended high-temperature operations to ensure optimal protection.

Q: Where can this furnace be installed, and what are the required ambient conditions?

A: Install the furnace indoors in environments with ambient conditions not exceeding 85% relative humidity (non-condensing). Ensure the site has stable power (220240 V, 50 Hz) and adequate ventilation for natural air convection.

Q: What is the process for replacing the heating element or thermocouple sensor?

A: Before any replacement, disconnect the electricity supply and allow the furnace to cool down. Open the split hinged chamber for easy access, and follow the manufacturers instructions for safe removal and installation of Kanthal A1/SiC elements or K-type thermocouple sensors.

Q: How does the split hinged design benefit users during operation and maintenance?

A: The split hinged mechanism allows convenient and secure access to the tube chamber, simplifying the placement and removal of tubes for both routine experiments and maintenance tasks, ultimately reducing downtime and handling risks.
