Please choose a product from our industrial furnace range below to view details.

Ashing Furnaces

One of the most common applications for laboratory chamber furnaces is to heat combustible samples in order to analyse the resulting ash residue. As there is no single solution for all requirements, Carbolite Gero offers a range of ashing furnaces with characteristics tailored to ashing and burn-off applications.

Maximum temperatures are as high as 1200°C with working volumes of up to 32 litres. A model with an integral balance for thermogravimetric analysis / loss on ignition testing is available and should you require an integrated afterburner to remove noxious fumes from materials such as biomass then Carbolite Gero's Afterburner Ashing Furnace could be perfect for your needs.

Annealing Furnaces

Carbolite Gero annealing furnaces are designed specifically for changing the physical properties of samples.

Carbolite Gero offers two different lines of annealing furnace, and within each line different models and options are available in order to meet your exact annealing requirements. The HRF air recirculating oven line contains bench-mounted as well as floor-standing models. The maximum temperature of each is 750°C, distributed across the chamber by powerful fans and horizontal air-guides for rapid heating and excellent temperature uniformity.

The GLO annealing furnace features CrFeAl heating elements in ceramic fibre insulation, providing a maximum temperature of 1100°C in the furnace’s vacuum tight chamber. There are three models in the GLO annealing furnace line: the standard GLO annealing furnace, the vertical VGLO, and the mobile GLO. Chamber sizes up to 260 litres are available. Please choose from our annealing furnace range below to view details.

Tube Furnace Range

Our tube furnaces provide excellent temperature uniformity and are ideal for heating small samples.

Each tube furnace in our range can be modified to meet your exact needs. When specified at the order stage our tube 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 of our 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.

Asphalt Binder Analyser - ABA

The integral microprocessor controlled weighing and calculation system is configurable to allow variations to the standard asphalt binder test method. Test result reports are available in both printed and software format. The high temperature afterburner minimises the production of noxious waste fumes. The asphalt binder analyzer is supplied complete with 2 sets of sample baskets.

MTT - Carbon14-Tritium Furnaces

A catalyst is used to ensure complete combustion of all thermal decomposition products. These are captured for liquid scintillation assay. This technique gives greater confidence of complete combustion than ‘wet oxidation’ techniques and avoids coloured contamination of scintillation media by botanical samples.

Computer control enables remote operation of multiple or individual units even in hazardous areas.

Coal & Coke Test Equipment

The range of coal and coke tests carried out in a furnace or oven has grown over many years, and Carbolite Gero has responded to the requirements of each new standard by designing a furnace to suit the specific requirements of each test method.

As a result, Carbolite Gero products are frequently specified as the reference equipment used in coal laboratories, inspection companies, power plants and steelworks throughout the world.

The range includes international coal and coke testing and iron ore evaluation test methods, including ISO, ASTM, EN, BS, and DIN. Please consult the Standards Overview Table to find the correct furnace for a particular standard.

If you have a question about a particular test method, please do not hesitate to contact our application specialists.

Crystal Growth Furnaces

The Bridgman method uses a pre-synthesized material that moves slowly through a temperature gradient. The melted material moves through a decreasing temperature gradient and forms a single crystal. The BV-HTRV is a tube furnace which is mounted on a device engineered specifically for the Bridgman method. As a standard, the HTRV 70-250 or the HTRV 100-250 are used as a tube furnace mounted on the pulling device. In principal, every tube furnace can be mounted on the pulling device. Most common are the two models, HTRV 70-250 and the HTRV 100-250.

Dental Furnaces - CDF

The CDF dental furnace is equipped with 3 robust high-quality heating elements made of silicon carbide. In contrast to many molybdenum disilicide heating elements these are free of any chemical interaction with zirconium oxide.

The dental crowns and frameworks are placed in sintering trays which are filled with a bed of zirconium support beads. The trays are designed to fit exactly in the furnace chamber. The bed of zirconia beads allows for a sintering process with low friction and results in distortion-free frameworks.

Precious Metal Furnaces

Thermocouple Calibration Furnaces - PTC

The PTC thermocouple calibration furnace is designed to provide a high stability portable heat source for the calibration of thermocouples using the comparison method.

Metal & Ceramic Injection Moulding Furnaces

Soldering Furnaces

The V-L is a vertically mounted tube furnace with automated controls for the sample loading and unloading, in addition to, raising and lowering the furnace hearth over the integrated quartz tube containing the sample material. The quartz tube is connected to the furnace, so in loading the soldering furnace, the quartz tube and furnace hearth are raised upwards to freely access the sample area. After the sample is loaded, the quartz tube and furnace hearth are lowered and locked into position for the heat treatment process where high vacuum operation is achievable. The furnace hearth can also be raised upward and away from the quartz tube after the heating process for fast cooling of the specimen in vacuum, air, or in an inert gas atmosphere.

Uniformity & Heat

To design and build a furnace with outstanding temperature uniformity, time-consuming calculations and simulations are required. Carbolite Gero has accumulated decades of engineering experience creating exceptional heat treatment systems.

This experience is utilised in all of our standard furnaces and ovens as well as custom modifications where temperature uniformity needs to be improved even further. Some important design principles to improve the uniformity are as follows.

High Pressure Furnaces

The LHT 100 bar range is a compact pressure laboratory furnace, for various applications mainly in research and development.

In the standard version, the LHT vacuum chamber furnace just is designed for high, fine or rough vacuum operation and atmospheric pressure. This pressure furnace is additionally suited for high pressure operation up to 100 bars at maximum temperature.

The high pressure vessel is designed by the aid of finite element simulation of the vessel, increased wall thickness, cylindrical design with torospherical top and bottom and TÜV certification by a high pressure test of the vessel with an incompressible liquid.

Attached to the pressure vessel it is equipped with special flanges, gauges, valves, pressure reducers and a safe bayoneted closing.

Fast Cooling

For most of the furnaces and ovens we manufacture we do not recommend rapid changes in temperature. This is to avoid inducing stresses in the materials being heated and cooled. If rapid cooling is required by your process then we can design to allow for this. A few standard products incorporate fast cooling and are included in the descriptions below.

Combined Furnace Racks

Many Carbolite Gero standard furnaces and ovens, along with the control box, can be stacked or built into bespoke racks either for space saving purposes or to suit specific customer application.

If toxic processes are carried out, Carbolite Gero can offer safe containment on one or several products.
