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)
