D In LESNI Preconditioning Cell the products are in a temperature and humidity controlled area. C A typical range for this preconditioning step is a temperature at 40 – 60 °C and relative humidity of 50 – 65 %.

Degassing Cell Degassing is the next step after sterilization to get residual ethylene oxide out of the packaging and products by aerating the cell with heated air. In LESNI Degassing Cell the products are in a temperature controlled environment, designed to ensure turbulent but accelerated air speed aro<strong>und</strong> the product to improve gas evaporation and reduce the degassing time. A typical operating range for this degassing step is a temperature at 40 –55 °C and several air changes. Aeration time may vary and is related to product type and different materials used, for this reason it is very important to have an efficient degassing and aeration stage to remove remaining EtO gas.
