10 May 2004, Stuttgart , Germany - The PulPaper 2001 was a record-breaking success and made this show to an international event of considerable importance for the global pulp and paper industry. From 1 to 3 June 2004 the 5 th PulPaper will take place again in Helsinki/Finland as a meeting place for all professionals of this field of business. This event will be accompanied by informative conferences dealing with current topics of this industry sector.

During the PulPaper 2004 we would like to present our oxygen generation systems OXYSWING® to you personally and will be happy to inform you about the use of our systems in the field of e.g. oxygen delignification, black liquor oxidation or as feed gas production utility for the ozone production at the ozone bleaching stage.

Our oxygen generation systems belong to the leading plants of their kind in the world and own a position in the forefront of the Pressure Swing Adsorption (PSA) technology due to their excellent product flexibility, high reliability, rapid on-line time, minimal space requirement and cost-efficiency. Make your oxygen requirement independent from road transportation, prevailing weather conditions or other problems by installing an on-site oxygen generation system directly on the premises of your production facilities.
