Tubular heaters are used for almost every kind of heating appliances. They are easy to form and
feature highest mechanic stability and electric properties at the same time. Even though tubular heaters
are technically rather mature and universal to use, there exist various new innovative solutions for many
applications. Thus flexible tubular heaters (see chapter 4.1) have developed to be a new industry standard
for the use in heating platens, welding bars and manifolds. Screw in tubular heaters are standardised for
use in liquids like water. Finned tubular heaters are especially for air-heating-cabinets or tunnels.
