RP System is applicable for museums, galleries, libraries, archives, cultural properties and so on. It does not require large-scale equipment for gas-fumigation but a heat-sealing machine only.

AIR-G, Automatic Relative Humidity Controlled Nitrogen Generator is available. It is to treat big cultural properties, up to approx. 3m3. For further Information, please ask your distributor.

RP-K type agent for non-metallic artifacts.

RP-K type absorbs oxygen and corrosive gas but not moisture. RP-K is to treat and to preserve nonmetallic cultural properties such as wood , paper , fabric, leather and so on. It is effective in insect proof and dust control of physical objects.

Oxygen indicators

An Oxygen indicator is to show the presence or absence of oxygen in sealed container by change of color. The blue color changes to pink as the atmospheric oxygen content becomes 0.1% or less.

This is used to check the initial effect of the RP System. Regarding detailed information, please contact us before use.

Other attributes using RP-K type agent.

As insecticide

It is known that eggs and larvae, pupae and imagos, will perish within two weeks under anaerobic conditions at room temperature. Under these conditions, eggs place inside the wooden ware will be killed. As this method adds nothing to the artifact, it is much easier and safer method than fumigation with insecticides.

  • eg. Artifacts made of wood, cloth, leather, paper or any combination of the aforemen- tioned materials.

Mold prevention

Any aerobic microbe including mold does not propagate under oxygen-free conditions.

  • Aplication examples: products made of paper, textiles, wood and leather
Mold prevention

With RP-K

Without RP-K

Prevention of Oxidation

Prevents the yellowing of paper due to aging.

aterpoofing cultural assets

Once cultural assets are sealed in Escal bags, the assets are not only protected from moisture and humidity but also flooding in case of a disaster.
