ABSTRACT:
A flow heater (11) has a stainless steel tube (1Z), around which is externally placed a polyimide (KAPTON) insulating film (14) with an overlap (15). Under pretension is wound onto the same a metallic resistance material heating tape (17), so that the resulting elasticity reserve, also at operating temperature, ensures a good application of the heating tape to the film. Temperature switching devices for preventing excess temperatures or running dry can be fitted in the overlap area (15).
