Heating arrangement with coated radiation emitting surfaces

A heating arrangement, comprising a combination of the following features:

• a) at least one heating element (3) in the form of a flat element with two opposite-lying electric conductors and a coating arranged therebetween comprising a coating material for radiation surfaces to produce electromagnetic waves, composed of binding agent, insulating agent, dispersing agent, water and graphite, characterized in that the coating material has the following composition
• i) 55 to 65% amount of substance (mole fraction) of a base material comprising:
• ii) 39 to 49% amount of substance binding agent, 18 to 23% amount of substance insulating agent
• iii) 18 to 24% amount of substance dispersing agent, 12 to 16% amount of substance distilled water,
• b. 35 to 45% amount of substance graphite, the composition of the binding agent being:
• i) 64 to 79% amount of substance distilled water
• ii) 4 to 6% amount of substance sulfated oil;
• 0.16 to 0.24% amount of substance phenols or 0.05 to 0.5% amount of substance benzoisothiazolinon;
• iii) 15 to 19% amount of substance casein;
• 0.8 to 1.2% amount of substance urea;
• iv) 2 to 3% amount of substance alkali diluent;
• v) 2.5 to 3.5% amount of substance caprolactam;
• and,
• whereby by means of the coating material from the insulating agent the graphite and the binding agent electromagnetic waves can be emitted,
• c) at least one controller/regulator (7) with a harmonic generator comprising an electrical component which when driven by a driving oscillation displays a rapid rate of current rise corresponding to a steep leading edge and thereby being suitable for the production of a high harmonic content;
• and,
• d) the harmonic generator is coupled to both electric conductors of the heating element (3) for the excitation of said element (3) in order to emit a spectrum of vibrations in the natural molecular frequency ranges.
