Atlas Copco welcomes WIMES blower update 15 June 2012
Atlas Copco has welcomed revisions to WIMES (the Water Industry Mechanical and Electrical Specifications), which emphasise measuring blower performance according to the ISO 1217 standard for displacement compressors.
"Atlas Copco has always believed and stated that providing the flow figures of a blower at the outlet, as specified under ISO 1217, is the only accurate way to measure and compare performance between blower technologies," explains Rob Boughton, low pressure sales manager at Atlas Copco Compressors.
"The increased emphasis on ISO 1217 under the revised WIMES will hopefully lead to a significant change in the industry's approach to blower performance measurement, which has traditionally been stated as an inlet flow measurement," he continues.
"ISO1217 will ensure customers are provided with a truer picture of blower efficiency and the volume of air that is supplied to their process."
WIMES guidelines have also been revised to include rotary screw blower technology for the first time, with water utility companies and contractors now able to use rotary screw blowers under WIMES 8.04.
Boughton reminds plant engineers that benefits include a reduction in energy costs by an average 30%, compared to lobe technology.
The decision follows a three-month review of blower technology by the Pump Centre, which has been responsible for compiling the guidelines.
"The decision to include rotary screw blower technology in the WIMES reflects the evolving needs of the water industry," comments Roger Marlow, principal consultant at the Pump Centre.
"Energy efficiency has become increasingly important to water companies keen to reduce total cost of ownership, which is why more and more companies are now turning to rotary screw blowers."
