We are a Portuguese company that acts in
conservation/disinfestations areas. We have converted some ethylene
oxide chambers that used to operate in National Library and in
Portuguese National Archives. These chambers started to work in
anoxic conditions 4 years ago and they still work with good results.

The system may work either with CO2 or Nitrogen. CO2 in room
atmosphere, above certain concentrations, may have a bad effect on
people, so outside atmosphere should be controlled (leaks or misused
may occur).
