BOTTLING / FILLING 39 PET planet insider Vol. 12 No. 09/11 www.petpla.net As the blow-moulding machine, Tirta Amarta uses a design-enhanced technology version of the Contiform. The complete valve rack, with its minimised volume of dead space, for example, consumes around 10% less compressed air than the preceding model. Unit costs downsized thanks to lightweighting Besides upgrading its technical equipment, Tirta Amarta also concentrated on cutting its unit costs through lightweight- ing. Tirta Amarta modelled its bottle on the weight-reduced PET container and together with Krones, the preform pro- ducer and the manufacturer for the preform moulds designed a 600-ml short-neck bottle without a support ring. The bottle, which features a neck finish customary in Indonesia, meas- uring 30mm outside and 25mm inside, weighs only 12.5g instead of the 16g usually found on the market. “Lightweight- ing demands physical compromises, of course”, concedes Rioan Silalahi. “The first and so far only placing of a light- weight bottle like this, however, secured us a competitive edge and cost advantages on the market.” Plans for more capacity upsizing Tirta Amarta is not resting on its laurels, however, and is aiming to design an even lighter water bottle. “We’re expecting annual growth of 15 to 20% in the Indonesian water market, since per capita consumption is still relatively low and per capita income is continuing to rise”, comments Plant Manager Endang Retnosusmawati. Tirta Amarta has plenty of plans up its sleeve: diversifica- tion into flavoured water, expanding the distribution network to other Indonesian islands … – and very soon now some more capacity upsizing, once again together with Krones. www.krones.com Lightweight bottle Excellent growth prospects DRYING HAS NEVER BEEN THIS EFFICIENT: ETA plus® LUXOR - now available with ETA plus ® ETA plus ® considerably reduces energy consumption and protects materials. When it comes to drying, saving energy is a key concern. We have developed a system that combines airflow regulation with a temperature adjustment feature – that can be disabled if required –and efficient waste heat recovery. The result? A drying system that cuts energy consumption by up to 64%: ETA plus ® . motan-colortronic gmbh [email protected] www.motan-colortronic.com Visit us at Fakuma hall B1 booth 1111
