VSD technology improves energy savings

over the short and medium term which will increase exponentially over the long term. Ackerman notes that compressed air installations present massive energy saving opportunities for end-users. “Through analysing, optimising and mon- itoring a compressed air network, we are able to minimise losses and maximise operational efficiency for the end-user.” He says that while there are a num- ber of areas in a compressed air installa- tion where wastage can occur, optimum air flow is one area in particular that can deliver significant energy savings. “This is where our VSD technology comes into its own. With energy savings of up to 35%, a GA VSD compressor is an investment in sustainable plant operation.” www.atlascopco.co.za

Air Business Line manager, energy con- sumption typically represents over 70% of a compressor’s life cycle cost. “In addi- tion to South Africa’s protracted energy crisis which is debilitating mining and industry through interrupted produc- tion, escalating energy costs is inevitable. Alternative energy sources like solar and wind power are very expensive and not always practical.” Forward-thinking industries

Atlas Copco Compressor Technique’s VSD technology substantially improves the energy efficiency of a compressed air sys- tem, resulting in significant savings and sustainable productivity. Compressed air is one of the most important utilities in industry but it is also one of the largest consumers of energy. According to Charl Ackerman, Atlas Copco Compressor Technique’s Industrial

that are already now committed to finding effective and sustain- able ways to conserve energy will reap cost saving benefits

Pioneered by Atlas Copco in 1994, the VSD compressor perfectly matches air supply to air demand in processes where air demand profiles fluctuate.
