We are specialized in the stabilisation of relative humidity inside
showcases and storage cabinets. We offer:

    Passive humidity buffers for stabilisation of RH within
    showcases and storage cabinets: PRO SORB for achieving a RH
    between 40 - 60% RH, (for most wooden artefacts, ivory.) or
    Silikagel Plus for achieving a RH between 20 - 40% RH, see

    Desiccants like silica gel, desiccant clay or molecular sieves
    (bulk or in bags) for achieving a RH between 0-40% RH (for
    metals), see <URL:>. Sometimes,
    the best solution is not to dry the whole storage cabinet but to
    seal the metal objects individually or boxes of metal objects
    into bags made of high-barrier materials. Sachets of molecular
    sieves can keep RH inside the bags close to 0%RH for decades
    without maintenance.

    Constant humidity generators, for climate control in showcases,
    either as separate modules (see
    <URL:>) or as central units
    with a pipe system distributing conditioned air to several
    showcases or storage cabinets (upon request).

    Sorbents against tarnishing of silver objects or activated
    charcoal cloth for adsorption of acid vapours inside showcases,
    see <URL:>

    Small hygrometers for showcases, see

    Dataloggers and humidity measuring systems for hygrometric
    measurements inside showcases or storage rooms

I am a graduated conservator restorer specialized in the field of
Preventive Conservation since many years, so you can be sure to get
the best possible advice for your specific applications. We export
all over Europe.
