Ceramic elements

For direct air heating or indirect liquid heating

DESCRIPTION

Elektrotermija produces a wide range of different heaters on ceramic bodies. Resistance coils are placed in longitudinal holes or grooves on oval, rectangular, hexagonal... ceramic bodies or suspended on ceramic bearers. Great advantage is possibility of replacing of the element without emptying container. In such cases elements are placed in protective tubes. Ceramic elements are also used in applications when increased wall thickness of the tube due to heavy pressure stresses is required. Heat is transferred by radiation, conduction, convection or forced convection.

APPLICATIONS

Indirect heating of liquids
Electrical water heaters, boilers, containers, tanks
Industrial baths, galvanic baths
Industrial furnaces
Oil pre-heaters, duplicators, reactors
Air pre-heaters, dryers, fans, hot air guns
Bakery and bread ovens, steam generators
Storage heaters
