majority of felt sheets, non-wovens, impregnated fabrics, etc. are just a few mm thick or up to 10-20 mm.<\/p>\n<p>In order to dry efficiently products having such thicknesses, some years ago Stalam has developed and patented an innovative electrode system, the double-polarity electrode, that ensures the following benefits:<\/p>\n<ul>\n<li>it can deliver higher RF power values (thus evaporating correspondingly more water), while working at significantly lower electrode voltages<\/li>\n<li>thanks to the lower electrode voltages, there are less energy losses in the air and the overall power consumption of the machine is lower, thus cutting energy costs by a further 10-20%<\/li>\n<li>thanks to the lower electrode voltages, all the machine\u2019s high voltage components are less stressed and the overall reliability of the machine is greatly improved<\/li>\n<li>thanks to the individually insulated multiple-rods design, the eventual centre-lateral sides moisture content differentials can be easily compensated by a suitable curve or inclination of the electrode rods<\/li>\n<li>thanks to the possibility to place the double-polarity electrode symmetrically above and below the product, the RF line fields can be concentrated specifically in the centre of the product and not on the upper \/ lower surfaces, so where the water has more difficulty to leave the product<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n\n            <div class=\"grid-img\">\n\n                            <a href=\"https:\/\/www.stalam.com\/wp-content\/uploads\/2023\/05\/RF60kW_felts-3.jpg\"
