GEA offers both WET and DRY sterilization technology for any PET preform, for any PET/HDPE bottle and for any kind of closure allowing filling of beverages with different pH on the same system.

In both WET and DRY technology a microbiological isolator equipped with intervention gloves provides a physical barrier between the external environment and the microbiological controlled area, where blowing, filling and capping processes are performed.

GEA Wet PAA technology for bottle and caps sterilization acts on both internal and external bottle and cap surfaces with a single PAA solution and a strong combined chemical and mechanical action.
Sterilization treatment is performed using penetrating nozzles. The efficiency of each nozzle is automatically checked by a ’Smart Sensor’ that ensures proper sterilization of each bottle.
GEA WET PAA FDA approved technology can be

applied to any bottle or closure with almost no limit on material, shape and size.

GEA Dry H2O2 technology for preform and cap sterilization uses a flow of Vaporized Hydrogen Peroxide at a controlled temperature, concentration, contact time and flow rate, to achieve high sterilization performances. The treatment takes place in a single step on body and neck internal and external preform surfaces after the oven, just before the aseptic blowing process. Caps sterilization is performed within a ‘sterilization chamber’.

GEA Dry H2O2 technology for bottles uses H2O2 in vapor form to treat internal and external bottles surfaces. Bottles in upright position are treated on a carousel and in a second one they are purged in order to have a low total peroxides residue. The H2O2 flow is continuously checked by the “Smart Sensor” with the aim to assure the right treatment to each bottle. Even cap or foil are treated with dry H2O2.
