Cylinder furnaces are made in two variants: up to 1300°C with the heating elements from the Kanthal-A1 material and up to 1550°C with the superkanthal heating modules.

The furnaces have vertical or horizontal set-up with 40-400 mm inside diameter. They enable for example insertion of the inner tube with samples and their testing in varied atmospheres or reduced pressure. Furnaces with various length or height of heating sectors can be constructed thanks to parallel heating modules.

The standard equipment of all furnaces is the programmable controller CLARE. The applied 8-bit microprocessor with supporting chips provides reliable function of the whole equipment. The controller works with a real time clock in the manual or automatic mode.
