Carbolite Gero HTR Rotary Reactor Tube Furnace range comprises of two models; HTR 11/75 and HTR 11/150. Both are rotating tube furnaces allowing heating and mixing under atmosphere. The Reactor acts as a fluidised bed furnace. Agitation of powdered solids is possible. Reaction times are reduced in comparison to those experienced by combustion in a muffle furnace or using a tube furnace.

The fluted internal surface of the quartz reactor ensures thorough mixing as the variable speed electric drive system oscillates the reactor tube through 315 degrees. The hinged heated chamber design allows easy loading and unloading of the quartz vessel. The vessel profile provides easy access for emptying and cleaning with minimal powder loss.

Furnaces feature resistance wire elements embedded in the vacuum formed insulation. The maximum temperature is 1100°c, and continuous operating temperature is 1000°C. Heating is radiated through the fused silica (quartz) vessel. Cooling time with the lid open is typically 15 minutes.

Suitable for calcinations, pyrolysis or reactive gas treatment of a great variety of powders and granulates with volumes up to 50 cm3 or 700 cm3.  A typical charge for the furnace would be moderately fine to coarse granular solids which do not contain significant quantities of dust.

A single seal gasket directs the reactor exhaust into a removable stainless steel exhaust box from where a gas outlet allows piping to an extraction system.
