round ceramic heaters

With closed or open grooves in ceramics

DESCRIPTION

Round ceramic heaters are used for indirect heating of liquids or direct heating of air. For these applications, the ceramic element is usually mounted in a tube.
Elektrotermija produces a wide range of heaters with round ceramic bodies. Resistance coils are placed in longitudinal holes or grooves. Groves can be open or closed. Ceramic shorter than 300mm with closed grooves can be filled with MgO powder. Heat is transferred by radiation and natural convection.
