Tubular elements air & gases

Wide selection of element sizes and types

DESCRIPTION

Years of experience and constant production improving have resulted in wide range of different tubular electric heating elements. These elements are the most common and the cheapest solutions for various needs. Elektrotermija produces tubular heating elements both for household appliances and for industry and special applications. We produce air tubular electric heating elements with mounted electrical and mechanical connections. These elements are made in straight or bend shape according to customers needs. Stainless steel tubular heating elements are the most versatile and the most represented product of electric heating industry and are foundation for production of numerous heating systems such as duct heaters, flow heaters, power resistors and many, many more. All elements are tested according to EN 60335-1.
