Product introduction
Electric Heating Element And Tube also named tubular heaters,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 resistance heaters are technically rather mature and universal to use, there exist various new innovative solutions for many applications.
