- This tube 182 is advantageously a stainless steel tube, or even corrosion-resistant, welded and sealed, and seamless, copper-plated alloy, preventing any corrosive attack of water or liquid on this alloy shell, enclosing this shielded resistance, and preventing any leakage that could be related to defective joints or screwing in the light alloy.
- welds prevents any problem of tightness in the fluid circulation.
- the double insulation provided on the one hand by a tube or a ceramic sheath, and on the other hand by the insulation itself of the armored resistance, gives the whole of this heating body the possibility of classification in double insulation, said class 2, which makes it possible, by avoiding a grounding conductor, to minimize the constraints related to the power supply cable: cost, flexibility, weight.
- a seamless stainless steel armor, and a double ceramic shield there is thus both a seamless stainless steel armor, and a double ceramic shield, and thus a high reliability and high security of use, at an economical cost.
- the invention has many advantages.
- the use of steam allows a temperature maintenance in the vicinity of the cleaning zone.
- the circulation of fluids, especially with their reuse, ensure a renewal of the cleaning flow, and high efficiency.
- These provisions also prevent fouling of the absorbent substrate implemented by the invention.
- the invention is very simple and provides a very light and maneuverable device. Circulations make it possible to use the laws of gravity for the collection of residues.
- the invention can do without suction means, which does not prevent it can be coupled to such means, within devices having a movable body on the ground.
