Röhrenheizung

Röhrenheizung, often translated as tubular heating or simply element heating, refers to a type of electric resistance heating element. It consists of a resistance wire, typically made of a nickel-chromium alloy, enclosed within a metal tube, usually stainless steel or incoloy. This resistance wire is insulated from the tube by a compacted magnesium oxide powder, which acts as an excellent electrical insulator and thermal conductor.

The tubular heating element operates on the principle of resistive heating. When an electric current passes through the resistance wire, it encounters opposition, generating heat. This heat is then efficiently transferred through the magnesium oxide to the outer metal sheath, which in turn transfers it to the surrounding medium. This medium can be air, water, oil, or other substances depending on the application.

Röhrenheizung elements are versatile and can be manufactured in various shapes and sizes to suit diverse heating requirements. They are commonly used in domestic appliances such as ovens, toasters, and water heaters, as well as in industrial applications like process heating, drying systems, and climate control. Their robust construction contributes to their durability and reliability. The design allows for precise temperature control and efficient energy transfer. Maintenance is generally minimal, making them a popular choice for long-term heating solutions.
