Tubular elements water & liquids

Proven and safe technical solution

DESCRIPTION

Years of experience and constant production improving have resulted in wide range of different tubular electric heaters for water and liquids. Our tubular heaters are manufactured with special care and attention to details, starting from calculations, choice of right materials for specific need up to rigourous testing. Tubular heating elements are usually bend in U shape, multiple U shape, spiral or other and soldered, brazed or welded to nipples, flanges.
We produce tubular heating elements from copper or stainless steel tubes. Copper heating elements are still widelly used for water heating due to excellent physical characteristics of copper, corrosion resistance and durability over years. 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 immersion heaters, flow heaters, galvanic heaters and many, many more. All elements are tested according to EN 60335-1.
