Deltech Vertical Tube Furnaces have been the favorite of petrologists since 1973 when NASA selected Deltech to design and build vertical tube quench test furnaces for petrologic studies of the moon rocks.
Rotary tube furnaces are well suited for manufacturing a range of materials, like alumina and iron ore pellets. The are also good for applications such as calcining, which require the continuous throughput of loose materials, and oxidation.
Horizontal tube furnaces are ideal for applications in which the sample size is relatively small in diameter, but processing in inert or reducing atmospheres or under vacuum is required.
