About Tube Furnace

Tube Furnace manufactured by United Enterprises is a compact, high-precision laboratory and small-industrial furnace where the workload is held inside a heated tube ideal for atmosphere-controlled heat treatment, sintering and material studies.

Brief Description:

Tube furnaces are popular in research labs, quality control departments and small specialty industries. The workload is placed inside a quartz, alumina or alloy tube, which can be sealed at the ends for controlled atmosphere (inert, reducing or vacuum) operation.

We offer tube furnaces in horizontal and vertical configurations, with temperature ranges up to 1700C and beyond, using Kanthal A-1, SiC or MoSi2 heating elements as appropriate. Programmable PID controllers and modern safety devices are standard.

Each tube furnace is built to the customers working tube size, temperature range, atmosphere need and process objective.

Characteristics:

Compact horizontal or vertical tube design
Maximum temperature up to 1700C as required
Quartz / alumina / alloy working tube
Atmosphere ports for inert / reducing / vacuum
Programmable 30-step PID controller
Imported heating elements (Kanthal A-1 / SiC / MoSi2)
Compact lab-bench footprint
Safety devices and rugged construction

FAQs:

Q: What temperature range should I choose?

A: Depends on your tests 1100C suits general work; higher ranges (up to 1700C) are for advanced ceramics and high-temperature research.

Q: Horizontal or vertical tube design?

A: Horizontal is more common; vertical is preferred for thermo-gravimetric and gas-flow studies.

Q: Is atmosphere control offered?

A: Yes. Inert, reducing and vacuum-capable versions with end seals and gas trains are available.

Exceptional Temperature Control and Precision

Equipped with a fully automatic PID temperature controller and SSR drive, this tube furnace guarantees accurate and stable temperature management. Its 1C temperature uniformity and digital display offer precise monitoring and regulation, essential for research and industrial processes where accuracy is critical.

Customizable for Diverse Applications

Available in standard and customizable tube lengths and diameters, this furnace is suitable for a wide range of experimental needs, including those requiring quartz, ceramic, or alumina tubes. The design supports applications from small-scale laboratory testing to larger industrial uses, ensuring flexibility and adaptability.

Robust Safety Features

Ensuring user safety, the furnace integrates an over-temperature alarm and automatic power cut-off. Double layer high-density ceramic fiber insulation further minimizes heat loss and external surface temperature. These features protect users and ensure reliable operation for prolonged laboratory or industrial use.

FAQ's of Tube Furnace:

Q: How does the fully automatic PID controller improve furnace performance?

A: The PID (Proportional-Integral-Derivative) controller with an SSR (Solid State Relay) drive maintains precise temperature settings, minimizing fluctuations and overshoot. This results in accurate and stable heating-crucial for processes like annealing or sintering that require exact temperature control.

Q: What heating elements can be chosen, and how does the choice affect usage?

A: You can select between Kanthal wire and silicon carbide rod heating elements. Kanthal wire offers excellent longevity and cost-effectiveness for most standard applications, while silicon carbide rods provide rapid heating and higher temperature capabilities, suitable for demanding industrial processes.

Q: When is it recommended to use gas-tight flange end fittings?

A: Gas-tight flange end fittings are ideal when you need to maintain a controlled atmosphere inside the furnace, such as inert gas environments for sensitive material processing. They help prevent contamination and ensure precise experimental conditions.

Q: Where can this tube furnace be installed for optimal safety and efficiency?

A: Install the furnace in a well-ventilated laboratory or industrial workspace, away from moisture and combustible materials. Ensure ambient temperatures do not exceed 40C and that the area is non-condensing to maintain safe and efficient operation.

Q: What processes and applications benefit most from this tube furnace?

A: The furnace is perfect for a range of tasks, including annealing, sintering, and material testing. Its accurate temperature control and customizable features make it well-suited for research laboratories, university departments, and quality assurance in industrial settings.

Q: How does the high-density ceramic fiber insulation contribute to performance and safety?

A: The high-density ceramic fiber insulation offers outstanding thermal retention, reducing heat loss and maintaining stable internal temperatures. Additionally, it keeps the furnace exterior cooler, enhancing user safety during operation.
