Sandoz Mumbai saves up to 17% on energy using Atlas Copco screw blower technology
Wilrijk, Belgium, August 2014: Sandoz Pvt Ltd. has achieved up to 17% energy efficiency and lower noise levels by choosing Atlas Copco low pressure screw blowers for its effluent treatment plant at their factory in Navi Mumbai, India.
Aeration air blowers typically represent up to 70% of total electricity costs
“Our low pressure screw blower was the right replacement for the old lobe blower, which consumed more energy and had very high noise levels. We installed a ZS 18 VSD (variable speed drive) blower in July 2013, and the customer noticed the results within a few months,” said R Narayanan, Business Line Manager, Oil-Free Air, Atlas Copco India.
Like Sandoz, many industries use air blowers for their processes, especially those that operate wastewater treatment plants where aeration air blowers typically represent up to 70% of total electricity costs. In the treatment process, a large quantity of air needs to be blown into the aeration tanks. This is one typical application that can benefit from the energy efficiency of rotary screw air blowers.
Atlas Copco’s latest ZS+ range of oil-free, energy-saving, positive displacement screw blowers is designed to meet today’s low-carbon economy needs. VSD technology can accurately meet demands for compressed air by adjusting air output based on actual use, reducing energy consumption when not loaded. The means that the energy consumption of the compressor can be considerably reduced.
