Tubular Furnace

A precisely manufactured high-temperature heating device with a cylindrical heating chamber called a tubular furnace is used to treat materials uniformly in a cylindrical-shaped heating zone. It is extensively utilized in industrial and laboratory settings for processes including thermal analysis, annealing, sintering, and material production in controlled environments. Samples can be heated in a vacuum-sealed or flowing gas environment thanks to the furnace’s horizontal or vertical tube structure. Tubular furnaces are perfect for manufacturing and research processes that need clean, repeatable heat treatment because of their excellent thermal uniformity, sophisticated temperature control and adaptable tube materials.
