Compressors PET planet Insider Vol. 18 No. 09/17 www.petpla.net 36 Efficient high pressure blow air production at Hansa-Heemann plant in Loehne, Germany with ABC compressor technology A Horizon-3000 for Hansa-Heemann After having launched its new Horizon for the PET industry in 2015, the Spanish high pres- sure compressors manufacturer ABC Compressors has celebrated the 200 th installation of this new range. The company’s main technical developments were the combination of the optimised design of the horizontal-boxer type with double acting compressors and the directly coupled transmission. This compressor range can be upgraded with two energy saving fea- tures, the Variable Speed Drive (VSD) and the Heat Recovery System, with noticeable impact on the energy TCO category and environment care. The VSD adapts, by means of a pressure transmitter, the compressor rotational speed to the real high pressure air consumption needed, maintaining at the same time the required working pressure in the pipe line. This reduces or even eliminates the compressor idle operation and the resultant waste- ful energy consumption. On average, it saves 20% of the consumed energy when running at half of the nominal air flow capacity, says ABC Compressors. This achievement is feasible thanks to the balanced operational torques and the absence of vibrations. The Heat Recovery System recy- cles the heat generated during com- pression to provide hot water (above 80°C) for the operation, allows extra savings and reduces the CO 2 footprint. The system is said to recover up to 45% of the energy consumed by the compressor. After each compression stage, hot air enters a first phase cool- ing 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 cool- ing phase. Using double circuits-phase in all the compressor coolers not only provides water flow at high tempera- tures but delivers overall Δt of 6-8°C for optimum compressor set thermo- dynamic efficiency. According to ABC, this is the only system on the market adapted to all the compressor inter- and after-coolers. Being vibration free, due to the well balanced torques distribution, the skid is placed directly on the floor, avoid- ing vibration pads. The compressor achieves efficiency below 0,16kW/m³ at full capacity without considering the VSD impact, thanks to the balanced compres- sion ratios between the stages, large cooling capacity and low transmission power requirements. Compressor installation at Hansa-Heemann Since the commercial launch of the Horizon at the Brau Show in Nuremberg in November 2015, many key players worldwide have trusted this technology, either for new installations or to replace old machinery. One of them, Hansa- Heemann, a supplier of mineral water and soft drinks in Germany, installed the Horizon-3000 for Loehne, one of their five plants, at the end of 2016.

Throughout the enquiry, selection, purchasing, installing and commission- ing process and during the initial approx. 4,000 production hours, the cooperation between Hansa-Heemann and ABC Compressors has been faultless and beneficial to both parties. ABC Compres- sors delivered the Horizon-3000 initially to the Brau Show. Hansa-Heemann and ABC Compressors group photo at the Brau Exhibition in Nuremberg, 2016. Since Hansa-Heemann provided an internet access, ABC monitors the Horizon-3000 online via its ‘Abil- ity’ Eye-surveillance system. ABC Compressors’ First and Second Level Support can access the compressor and visualise all the operational para- meters in real time. This includes the historical data for a predictive diag- nosis. Thanks to the weekly report, ABC Compressors provides reliability and a good performance guarantee to Hansa-Heemann where the new com- pressor is working 90% of the time, adapting perfectly to the plant’s high pressure requirements. The compressor operates loading 90% of the time due to VSD. www.abc-compressors.com
