At IWEX 2014, Atlas Copco Compressors will be exhibiting an array of energy-efficient compressed air products specifically designed for the UK water and wastewater management industry. This will include Atlas Copco’s ZS range of high-efficiency, oil-free, rotary screw blowers, as well as the company’s recent breakthrough innovation, the energy-efficient and compact GA VSD+ compressor.
For the first time at IWEX, Atlas Copco will be displaying a model from its GA 7-37kW VSD+ compressor range, launched in 2013, which was recently expanded to include models up to 37kW. GA VSD+ compressors provide energy savings of 50 per cent on average, a 13 per cent leap in Free Air Delivery and a canopy less than half the size of traditional fixed-speed compressors. This breakthrough in energy efficiency is made possible by Atlas Copco’s own 100 per cent patented interior permanent magnetic (iPM) motors which drive, and form the heart, of all GA VSD+ compressors. The GA 7-37 VSD+ is suitable for a range of applications in wastewater and clean water treatment plants including sand filter fluidisation, sludge tank aeration, sludge suspension, dissolved air flotation, surge vessel control, pneumatic control of valves and filter back flushing and cleaning.
Visitors to stand B10 will be able to hear about the technical superiority of Atlas Copco’s innovative and energy-saving ZS low-pressure blower range, which integrates the proven benefits of oil-free, rotary screw technology. Designed to meet water and wastewater treatment plant’s requirement for greater energy efficiency and a lower carbon footprint, ZS screw blower technology is claimed to be, on average, 30 per cent more energy efficient compared with the majority of conventional lobe-type, low-pressure blowers currently available on the market.
Products on show from the ZS range will include a standard ZS18 blower, and a weather-proof ZS18+ variant, which is fitted with an integrated VSD frequency converter that varies the speed of the motor to match changes in the blower air demand, thus consuming less energy.
Atlas Copco’s experts will also be on hand to highlight the technical differences between modern low-pressure and traditional lobe blowers, and to discuss the critical performance measurement factors that should be taken into account when comparing the two technologies. In addition, visitors can enquire about how their specific water and effluent treatment needs can be met with Atlas Copco’s complete portfolio of oil-free blowers and compressors for wastewater treatment applications and processes.
