Body and closing flange made of aluminum alloy. IP68 Degree of protection with Full Dry system which avoids condensing inside the product. Supplied with eletronic power surge protection. Nano with constant-current transformer, to be wired in parallel. NANO XL and XXL to be powered directly at 230V. For all-grain versions in A4 stainless steel. The product is subjected to galvanic anodizing treatment divided into distinct phases: mechanical satin finishing, surface degreasing, anodic oxidation and finally fixing. Subsequently the product is painted by performing a double pass in-line process, which allows you to generate a single thick protective layer which then generates barrier against atmospheric agents and UV rays. This allows to achieve corrosion resistance performance in salt spray. Pre-treatment with atmospheric pressure plasma is carried out on the surface before gluing of the diffuser on Platek products.
