Tube Furnace Details

Each tube furnace can be modified to meet your exact needs. When specified at the order stagetube furnaces can be upgraded to include sophisticated digital controllers, programmers, and loggers. Over-temperature protection is also available along with additional safety features such as insulation plugs and radiation shields.

Some Carbolite Gero tube furnaces are designed with an integral work tube while others require a separate work tube. This is an extremely flexible arrangement; work tubes are available in different diameters and materials (quartz, ceramic or metal). When a work tube of an adequate length is used, a standard tube furnace can easily be upgraded for use with a controlled atmosphere or a vacuum.

Typical applications of tube furnaces include the purification, coating, drying, hardening or ageing of samples. Among other uses, a tube furnace can also be used for annealing, brazing, calcination, degassing, sintering, soldering, sublimation, synthesis, and tempering. In a laboratory a tube furnace could be used for thermocouple calibration, in the testing of fuel cells, or in catalyst research.

The intended use of your tube furnace will govern which furnace is most suitable for you. Our tube furnace selection ranges from simple and economical options such as the wire wound single zone tube furnace through to more advanced systems such as the AZ tube furnace, which has eight independently controllable heating zones. The controllable heating zones of the AZ tube furnace allows a temperature gradient to be set for applications such as chemical vapour deposition.

Vacuum Furnace Options & Applications

The vacuum furnace range offered by Carbolite Gero includes vacuum chamber furnaces, vacuum hood furnaces, bottom loading furnaces, laboratory vacuum furnaces, and vacuum tube furnaces. Each furnace can be used with either a reactive gas or an inert gas. The majority of products in our vacuum furnace range are available with either metal, graphite, or ceramic insulation. On request, graphite models can be configured to safely operate at up to 3000°C.

Many different options are available for the vacuum furnaces range at the order stage, including advanced software, data loggers, and sophisticated digital controllers. These facilitate additional levels of control over the operation of the vacuum furnace and provide complete data recording capabilities. Furthermore in some cases different pumps, vacuum systems, and cooling systems can be provided in order to meet specific requirements.

All of our vacuum furnaces feature a robust construction and can provide rapid and highly consistent heating in a controlled atmosphere, making them ideal for numerous heavy duty industrial and laboratory applications.

Common applications of a vacuum furnace include brazing, sintering, annealing, degassing, drying, tempering, soldering, quenching, and hardening. A vacuum furnace can also be used for metal injection moulding (MIM) or ceramic inject moulding (CIM) as well as metallisation, siliconization, carbonisation, and other industrial processes.

Different vacuum furnaces will be best suited to different functions. Vacuum hood furnaces provide the highest possible purity while vacuum furnace models with bottom loading capabilities allow easy access to samples. Laboratory vacuum furnaces have a more compact design than other models, making them well suited for a research environment. Carbolite Gero vacuum tube furnaces are based on the according non-vacuum models, but modified and equipped with a purpose-built vacuum unit. Therefore, a large range of diameters and lengths are available. In the case of the HTRH-H2, Hydrogen atmospheres are possible as well.

Furnace & Over Custom Designs

Even with one of the most varied and extensive ranges of furnaces and ovens available, there are still occasions when a standard design simply does not meet a user’s precise requirements. That is when the real advantage in dealing direct with the manufacturer becomes clear, especially a manufacturer, who has the breadth and experience that Carbolite Gero possesses.

We can easily quote modifications or even a custom built furnace or oven. It may be something as simple as needing one of our standard products just a little larger or smaller, or to reach a higher temperature. Alternatively it may be a design that is required for a standard test method or to work within standards compliant regimes such as AMS 2750E or Nadcap for heat treatment applications.

In these situations Carbolite Gero has the experience and skills to modify our standard designs or engineer bespoke solutions in order to achieve the appropriate levels of compliance.
