Screw Blowers, Energy-Efficient

Atlas Copco Compressor Sales, a division of Atlas Copco (India) Ltd, Atlas Copco has announced its new and proven energy-efficient technology for air blowing applications: the ZS Screw Blower. Screw technology on average is 30 per cent more energy efficient compared to lobe technology. Since the lobe technology, widely used at present, no longer meets the needs of today’s low carbon economy. Industries and applications such as wastewater treatment, pneumatic conveying, power generation, food and beverage, pharmaceuticals, chemicals, pulp and paper, textiles, cement, and general manufacturing will highly benefit from energy savings through replacing the conventional lobe with the leading screw technology. The ZS screw blower will replace the company’s entire range of ‘Roots’ type rotary lobe blowers. In a typical biological wastewater treatment plant, the aeration blower system accounts for up to 70 per cent of the energy usage. Today the majority of these plants use less efficient lobe technology, a technology that has had little development since its introduction in the late 19th century. By reducing the energy usage of their aeration blower system, these plants will decrease their energy costs while operating in a more environmentally friendly manner.
