  • The world’s first ErgoBloc L wet-end system with an hourly output of 100,000 0.5-litre PET or rPET bottles is a big hit with customers.
  • Within just a few months, international clients ordered nearly 30 of these high-performers.

Since it was launched over 14 years ago, the Krones ErgoBloc L has taken care of the blow-moulding, labelling, filling and closing of PET bottles in a single, highly efficient system. Its efficiency was once again demonstrated last September at the drinktec, the world’s biggest trade fair for the beverage and liquid-food industry, where a block-synchronised system was able to produce 100,000 bottles per hour for the first time.

Just under 30 of these high-speed blocks were sold within a few short months, six of them to customers in the Middle East. This goes to show that the ErgoBloc system meets the needs of beverage producers all over the world, both by achieving the required performance and by helping to put the production process on a more sustainable footing.

Higher outputs result in improved sustainability

When compared to a 72,000-bph block, the new ErgoBloc L, rated at 100,000 bottles per hour, not only boasts better performance, it also provides substantial energy savings. Technical upgrades in the heating tunnel, for example, reduce energy consumption by more than ten per cent and the amount of compressed air in the stretch blow-moulding process by 20 per cent. What is more, up to 3,600 tons of CO2 per year can be saved if 100 per cent rPET is used.

The high-speed ErgoBloc L reduces both media consumption levels and the footprint required for its installation. It needs up to 70 per cent less space than conventional systems. The block also scores highly when it comes to process dependability. State-of-the-art automation technology ensures that it continues in operation even if one of the two fillers fails, and that the blow-moulder is emptied, thus preventing an immediate standstill in the block and minimising the scrap rate.
