Fibrothal® GSO

The Fibrothal® GSO is a vacuum formed heater module with Kanthal® strip heating elements. The strip heater design gives high power, rapid ramping at low temperatures and very good heat distribution. Support jigs are not required.

Fibrothal® GSO is used in many different applications including continuous furnaces, powder sintering, brazing and glass annealing.


The Fibrothal® GSO heater module has a unique support structure for fixing in tough conditions which contributes to a vastly improved service life and provides power loadings up to 100 kW/m2. The module offers high temperature uniformity while being flexible in design (i.e. vertical, horizontal, wall). Insulation thickness is very slim (min. 45 t) while retaining mechanical strength. Line voltage applied (50V/100V/200V/380V)
