In addition, ELGi managed to install and commission the installation within 3 weeks after we placed the order as per the contractual agreement.” Operational and socio-economic imperative Chris Ringlstetter, president at ELGi Europe, comments: “At ELGi, we realise that energy efficiency is more than a buzzword – it is an operational and socio- economic imperative as well as being market and industry specific. Compressed air in Europe accounts for approximately 10% of Europe’s total energy output. Energy savings compliance norms for companies in The Netherlands are quite stringent. ELGi’s EG Series with its built- in variable frequency drive, and the lowest power consumption in its class, has proven instrumental in reducing the total energy consumption of Rubber Resources’ 24/7 manufacturing operations.” The EG Series of oil-lubricated ELGi Compressors Europe, a subsidiary of ELGi Equipments Ltd, has completed an upgrade of the compressed air system at the Rubber Resources’ BV manufacturing site in Maastricht, The Netherlands. Following the modernisation project, Rubber Resources – a major player in rubber re-manufacturing in Europe – reportedly experienced increased efficiency and lower energy consumption which contributed to lowering its carbon footprint. Gerrit Rehorst, general manager at Rubber Resources, says: “Rubber Resources specialises in the recycling of rubber waste, mainly butyl inner tubes and the treads of heavy vehicle tyres, into a sustainable and cost saving alternative for the rubber industry. Our mission is the sustainable re-use of rubber thus it is our priority to make our processes, especially our compressed air, as energy efficient as possible. It was therefore an easy decision to replace the existing 180kW compressor with a 110kW Variable Speed ELGi EG Premium Series unit, which resulted in us achieving class leading energy efficiency, reliability and low maintenance costs with a support ELGi Compressors delivers energy efficiency compressors provides customers with high-quality compressed air in the harshest environmental conditions, all while ensuring minimal downtime. One of the key attributes of the EG Series is that it incorporates ELGi’s oil-injected screw element, designed to providing long life at a low operating cost. The entire EG Series package houses the ELGi designed screw element with ELGi’s ?V rotor profile, which is claimed to be highly efficient and much slower running versus most other units on the market. The in-built ELGi CONSERVE Variable Frequency Drives (VFD) matches compressor output with demand by varying motor speed – reducing power consumption in line with the reduction in demand. Compared with a compressor without a VFD, over a 10- year operating period, an EG Series is claimed to be able to offer a 34% reduction in energy costs. www.elgiaircompressors.eu
