But other applications are 24/7, with the bills for electrical power consumption, costs of maintenance and repair not being neglected. This is where Pneumofore A Series air compressors are installed, as the total ownership cost is considerably lower than other solutions. An important installation in Europe requiring 4 bar(g) [72,5 psi(abs)] with severe criteria of reliability and efficiency, is being prepared with a total of 6 compressors of model A180 and A260, the total nominal installed power is 660 kW [900 hp]. With 2,5 bar(g) [50,7 psi(abs)] as lowest pressure, these units can set the compressed air value with a precise digital pressure switch. The Pneumofore engineering team is happy to collaborate with intelligent customers who consider the long term operation and the total Life Cycle Cost, customers who know that the purchasing price of such an installation is about 8% of the total cost over 10 years only. Price dumping made by large competing companies, like discounts as high as 50% on list price, are ridiculous, as they still do not solve their important problem regarding long term operational, maintenance and repair cost.
Several processes at low pressure of about 2 bar(g) [43,5 psi(abs)], like pneumatic conveying in silos, use dry screws.
