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 <URL:http://www.CWaller.de/eprosorb.htm> 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:http://www.CWaller.de/esili.htm>. 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:http://www.CWaller.de/eminiClima.htm>) 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:http://www.CWaller.de/sorbents.htm> Small hygrometers for showcases, see <URL:http://www.CWaller.de/measurin.htm> 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.
