Innovative surface protection

  • Following nature (lotus effect)

    In Asia, the lotus flower is considered a religious symbol of purity. Moisture rolls off, and no dust adheres to its surface. It's all down to nano-particles: Minute papillae repel water. In nano-technology, this principle has been transformed into a self-cleaning ceramic. Materials coated with nano-particles have special properties: Scratch-proof spectacles are made by applying nano-particles to the surface. The lenses do not scratch even if cleaned with steel wool. The minute particles are so small that they cannot refract or diffract light, but instead allow it to pass through unhindered.

  • How does it work?

    The nano-seals are made of nano-particles with components that become firmly attached to the surface and to other components that create the desired effect. These particles arrange themselves intelligently during the application process. The binding components migrate to the surface, whilst the anti-adhesion components move towards the air. This "self-organisation" creates an ultra-thin, glass-like layer which forms a homogeneous connection with the surface, thereby ensuring extreme durability. This also protects the surface against aggressive environmental influences. The same form of nano-coating is also used in Rittal enclosure cooling units (condenser surface).

  • Nanotechnology – A vision transformed into a product

    Nanotechnology is used as standard in enclosure climate control devices. The condensers in TopTherm cooling units are given a nano-coating comprised of ceramic nano-particles which add a dirt-repelling layer to the condenser. The pores are permanently sealed, thereby preventing foreign substances from adhering to them, so that the surface properties are maintained. In "dirty" environments, this allows servicing intervals to be significantly extended. Innovative pre-treatment techniques based on nanotechnology offer truly eye-catching benefits:

  • Nanotechnology in primers

    As one of the world's leading enclosure manufacturers, Rittal is now further enhancing its international product range with a primer-coating technology guaranteeing optimum performance right into the very last corner: nanotechnology. Innovative nanotechnology-based priming techniques offer benefits which can only be described as eye-catching:

    Superior quality

    • Significantly improved corrosion protection thanks to a sealed, inorganic, high-density layer embedded with nano-particles
    • Enlarged surface provides for optimum final-coating adhesion

    More eco-friendly

    • Free from phosphates, solvents and toxic heavy metals
    • Reduced energy input, as no heating is required for application


    • Better long-term equipment protection
    • Significantly reduced maintenance

    The nanoceramic surface coating of our products replaces conventional iron phosphating.

    As a genuine innovation in surface engineering, this technology is a perfect solution for the priming of steel, zinc and aluminium surfaces. It permits extremely even coatings and significantly improved corrosion protection for coated surfaces.
