        of cleanroom and cleanliness technology ensures sterile, microbiologically contamina-
        tion-free supply air, circulating air and exhaust air. The degree of permeability of the
        textile used can vary and it can be designed as a flexible, elastic or rigid layer. Materials
        that can be decontaminated and sterilised in regular operation by UV light of wavelength
        222 nm were selected specifically for their use in controlling virus-based contamination.
        f   After cleaning and sterilisation, the Quarantine -CAPE is designed for multiple use.
        f   Intelligent, mechanical interfaces allow individual Quarantine units to be linked to
            form larger overall systems (see figure 7, right side), so that complete sports halls
            can be converted to virus-controlled single-person containment within short times.
        f   The pandemic-specific, cleanliness-controlled quarantine systems have very low
            operating costs due to small-volume multilayer systems.
        3.4 Hygienic-CAPE – designed to meet specific pharmaceutical
        industry requirements
        For the use of temporary, locally limited production capacities for pharmaceutical prod-
        ucts, GMP standards must be met above all, in addition to the cross-industry cleanliness
        specifications already listed. For this purpose, the surfaces must be designed in such
        a way that no reproducible microorganisms, viruses, bacteria, germs or fungi can settle
        on the surfaces. At the same time, the materials used must not be metabolisable. This
        circumstance is countered by the use of foil-like materials instead of the frequently used
        textiles. These are easy to clean, can be disinfected, are highly resistant to chemicals,
        have low outgassing behaviour and dissipate electrostatic charges in a defined manner.
                                                                                                 CAPE –
        The supporting structure of the Hygienic-CAPE is made of a stable, corrosion-resistant
        stainless steel frame. This surrounds the CAPE protective cover so that no undercuts     FLEXIBLE,
        or poorly cleanable composts are installed in the interior area used for the production   PORTABLE,
        and handling of pharmaceutical products. All construction elements and connecting        CLEANROOM
        components are hygienically designed.
        Air conditioning is carried out using HEPA filters in combination with irradiation units
        to reduce biocontamination. Humidity-controlled air conditioning systems must usually
        be used to keep powdery substances free of unwanted agglomeration, e.g. in tablet
        production. Air locks with dedicated pressure cascades are used to ensure the absence
        of contamination in the internal production area of the CAPE.

        3.5 DryClean-CAPE – to achieve very dry and at the same time
        very clean environments
        For individual, specific applications, such as battery cell production, not only highly
        clean but also very dry manufacturing environments are required. Along with the rapid
        development in the production of battery-powered vehicles, research and development
        environments and initial prototype production areas are needed at very short notice. The
        short-term demand for humidity- and cleanliness-controlled fixed installations cannot be
        met, also due to interrupted supply chains, so that mobile production environments that
        can be installed at short notice have to be used. With the CAPE emodiments described
        above, the dryness requirements cannot be met due to the high water permeability of
        the textiles used. Instead, a double-shell version of a DryClean CAPE has already been
        successfully used by a battery manufacturer for prototype production. This dry clean-
        room system, which is equipped with separate material and personnel locks, meets a
        dew point of -40 °C (0.08 g/kg abs. humidity) and an air cleanliness class 5 according to
        ISO 14644-1 for a production area of approx. 150 square metres. In order to reduce the
        special challenges of electrostatic charging of surfaces in extremely dry environments,
        the use of an ESD floor in the DryClean environment is indispensable.

        CAPE data in general
