Carbolite RHST & RHZS Rotating Horizontal Split Tube Furnaces

The range of Carbolite RHST & RHZS Rotating Horizontal Split Tube Furnaces offers the benefits of simultaneous heating and mixing of the sample, in addition to the use of an inert atmosphere.

The furnaces are suitable for continuous material processing. Residence time in the heated zone depends on the degree of inclination and the rotating speed (which can be controlled by the customer) and the length of the working tube, in addition to the flow properties of the material.

The design of the split furnace, drive system and feeder/ collection assemblies allows the work tube to be easily removed and replaced.

The single zone and 3-zone split tube furnaces have a maximum operating temperature of 1150 °C. All models are available with heated lengths of either 600 mm or 900 mm. The angle of inclination can be easily adjusted between horizontal and 10 °. The ceramic (IAP) work tube has an inner diameter of 75 mm. A safety switch automatically prevents heating and tube rotation when the furnace is opened.

It is essential to discuss your application with Carbolite Gero to ensure the suitability of the material for use in this equipment. Carbolite Gero cannot accept responsibility for your process due to the possibility of the material becoming sticky when heated and therefore not flow through the work tube.
