BOTTLE MAKING 30 PET planet insider Vol. 12 No. 04/11 www.petpla.net New bottle designs and integra- tion of intelligent ventilation systems could help to reduce the amount of compressed air used. Tests also focused on the aspect of compressed air recycling through Airback sys- tems. The Okertaler mineral water bottling plant uses two air recycling systems. Some of the compressed air in the newly inflated bottles in Airback System 1 is extracted and used to blow mould new bottles in Energy-saving potential of the InnoPET Blomax Series IV as opposed to Series III technology other stations. Airback System 2 regulates the recirculation of residual compressed air back into the com- pressed air system itself. A reduction in compressed air consumption of 31% is estimated. An additional 5% saving can be predicted if the there is a change in the shape of the bottle; in total, this would result in 36% less compressed air consumption, which, in turn, generates a yearly cost cut of €26,000 at €0.10 per kWh. Results First results show that considerable savings in materials, electricity, and compressed air can be made.criteria and characteristics have been defined and the current state of the stretch blow moulder, which is equipped with state-of- the-art measurement systems, has been recorded and consumption has been minimised. The remaining project objectives are to continue to assess and opti- mise the amount of material, energy, and compressed air, and also to research new heating technologies. Final results will be published at the end of 2011. www.khs.com PET bottles undergoing a top load test using finite element analysis For further information please contact: info@gabriel-chemie.com www.gabriel-chemie.com Innovation Don’t compromise on quality.
