Flexible Tubular Heaters

Homepage Products Tubular Heaters  Flexible Tubular Heaters

Square stainless steel tubular heaters BASE-flex (1.4541) are a reliable industry standard for the use in heating platens and manifolds.

In contrast to traditional tubular heaters with a round section which have to be bent by machines, square BASE-flex can be fitted into any rectangular groove with simple hand tools. Moreover, the square shape results in a bigger heat emitting area of up to 80% compared with a corresponding round section. Finally, the easy manual mounting saves the usually high technical expenditure for casting-in / soldering / cementing of bent round tubular heaters.

A soft version of the BASE-flex, the NICKEL-flex (2.4068) is available as special execution. Due to the soft, easy to form nickel material, the NICKEL-flex is suitable for manual mounting with hand tools in round sections, too. Furthermore, Nickel has a better capability to conduct heat compared with stainless steel.
