Product Description
The NACHZS 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.
Excellent uniformity results from division of the heated length into 3-zones each with its own controller and thermocouple. 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. A vertical equivalent of the NACHZS range, the NACTVS range is available.

FAQs of NACHZS - Horizontal Split 3 Zone Tube Furnaces:
Q: How do I operate the NACHZS Horizontal Split 3 Zone Tube Furnace for uniform heating?
A: To achieve uniform heating, program each of the three zones using the PID controller according to your process requirements. After securely loading your tube (quartz, alumina, or stainless steel) into the horizontal split chamber and closing the hinged door, monitor the digital display for real-time feedback. The systems 3C temperature uniformity ensures even heat distribution throughout the process.
Q: What materials are compatible with the furnace tubes, and how can I adjust tube size?
A: The furnace is compatible with quartz, alumina, and stainless steel tubes. Tube diameters are customizable from 50 mm up to 100 mm, allowing you to tailor the heating chamber to your experiments needs. Contact the manufacturer or supplier to specify your preferred tube size during purchase.
Q: When should the over-temperature alarm and forced air cooling features be utilized?
A: Engage the over-temperature alarm whenever operating the furnace near its maximum temperature (up to 1200C) or when processing materials sensitive to overheating. Forced air cooling is recommended during rapid cooling cycles or when faster temperature reduction is required between heating intervals.
Q: Where can this furnace be used, and what are its primary applications?
A: The NACHZS furnace is suitable for laboratory and industrial environments, specifically for heat treatment processes in research institutions, metallurgy, and materials science. Its durable construction and high temperature accuracy support a wide range of thermal applications and sample preparations.
Q: What is the process for data logging and temperature measurement with this furnace?
A: Temperature measurement uses K-type thermocouples, with the digital display providing live readings. For data logging, the optional USB interface can be configured to record and transfer temperature data to your computer, facilitating analysis and process documentation.
Q: How does the horizontal split door design benefit users during operation and maintenance?
A: The horizontal split, hinged door provides easy and safe access for loading and unloading tubes. This design also simplifies routine maintenance and cleaning, improving overall operational efficiency while minimizing heat loss during access.
Q: What are the main benefits of using the NACHZS 3 Zone Tube Furnace in a heat treatment application?
A: Key benefits include high thermal efficiency, precise temperature accuracy (1C), programmable multi-zone control, robust construction, and versatile compatibility with various tube materials and sizes. These features enhance process flexibility, reproducibility, and safety in demanding laboratory or industrial environments.
