ARak TWIN thin-bed heating mat for indoor use Twin heating-cable design, heat is generated by forward and return conductors made from 7-strand wire. Fully assembled, with 3 m PTC thermistor connection on one side only. Both conductors are insulated with solid PTFE (Teflon®) plus a multi-overlapping polyester insulating layer and very dense protective copper braid, covered with an outer PVC sheath. For optimum installation, the heating cable is stitched onto fibreglass mesh, ensuring even spacing and fixing. By heating in both directions, the specific wattage per metre of heating conductor is distributed across both heating conductors, which ensures optimum heat distribution and longer service life, as the demand on each heating conductor is halved. The heating mats can be adapted to any room geometry. Can be supplied in sizes ranging from 0.5 m² to 10.0 m² and with outputs of 160 W/m2 or 200 W/m2 VDE certified in accordance with the latest pan-European standards DIN EN 60335-1/60335-2-96 and DIN EN 50366.
