COMPRESSORS 18 PET planet insider Vol. 17 No. 05/16 www.petpla.net consumed energy when running at half of the nominal air flow capacity. This achievement is feasible thanks to the balanced operational torques and absence of vibrations. The Heat Recovery System, where the generated heat during the compression is recycled to provide hot water (above 80°C) for the customers (allowing an extra amount of savings and reducing the CO 2 footprint). The system is said to recover up to 45% of the consumed energy by the com- pressor. After each compression stage, hot air enters a first phase cooling chamber where it is cooled down to 80-90°C. From the chamber ABC provides hot water to the customer while the air continues to the next cooling phase. Using double circuits- phase in all the compressor coolers not only provides water flow at high temperatures but delivers overall Δt of 6-8ºC for optimum compressor set thermodynamical efficiency. According to ABC, it is the only system on the market adapted to all the compressor inter and after coolers. Group’s multisourcing project in Italy. With the activation of the new Natu- rae source in Castrocielo, Nestlé Vera adds the third pillar to the virtuous triangle that the brand has outlined in Italy. It already has a source in the North in San Giorgio in Bosco, and one in the South in Santa Rosalia. The marketing plan for the Castro- cielo plant, at operating speed, entails the production of approximately 220 million litres in the first year, with clear margins of growth in the following years. San Pellegrino´s Castrocielo plant is said to bring innovation to the mineral water bottling segment, both for the production and distribution model. In line with Nestlé’s commit- ments to environmental sustainability, the factory will only use green energy from renewable sources such as solar power. It will also incorporate LED lighting and systems for heat recovery and storage. With high pressure blowing air responsible for a large part of the bot- Direct coupling transmission detail with the gear box in between The compressor is said to achieve outstanding efficiency of 0.135kWh/m 3 before considering VSD and hot recovery impact, thanks to the bal- anced compression ratios among stages, large cooling capacity and low transmission power requirements. According to San Pellegrino objec- tives, the Horizon-2400 compressor, fitted with additional energy saving devices, is said to achieve energy savings as follows:  An average of 12% energy con- sumption reduction is granted by the adaptation of the Variable Speed Drive, reaching around 60% saving with low blowing air demand.  46% of the 355kW installed power is provided for other plant services in form of hot water at 80-90ºC. Overall, around 75-80% of the energy consumed for producing high pressure air in older traditional instal- lations is saved or recovered for other applications by the new compressor. www.abc-compressors.com A new horizon for Nestlé waters Since its market kick-off many key players worldwide have trusted this new technology, either for new instal- lations or for old machinery replace- ment. Among the ones who decided to install a Horizon unit in a new green field project are Nestlé Waters and its Italian subsidiary San Pellegrino. With an investment of 16 million Euros, San Pellegrino, Nestlé Waters, has started operation of its new min- eral water bottling plant in Castrocielo, Italy. The plant will bottle Nestlé Vera Naturae mineral water, completing the Heat recovery system diagram tling line energy consumption, San Pellegrino trusted ABC Compressors to meet its costs and environment objectives. Starting with a bottle pro- duction for 220 million litres, growing in the coming years, the new Hori- zon-2700 was selected and installed. With a motor installed power of 355kW the compressor set produces a high pressure air flow of 2,440m 3 /h FAD. Supplied as self-contained package, even the ancillary equipment as elec- tric cabinets, dryer, receiver, arrived installed on skid and interconnected. Being vibration free, due to the perfectly balance torques distribution, the skids are placed directly on the floor, avoiding vibration pads. Horizontal ABC arrangement at Castrocielo
