Despite its abundant use, it is a complex medium to control, resulting in high operating costs. In an unmonitored installation, as much as 90% of the losses in heat generation and distribution can be linked to leaks. Compressed air costs can be contained by regularly analysing energy requirements and through technological monitoring. This applies to all new compressed air system.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>Defining the requirements for the installation of a new compressed air system<\/h3>\n\n\n\n<p><strong>Analysis of the current situation<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Determine the parameters of the existing installation, e.g. age, general condition, pressure level, minimum and maximum flow rate, energy consumption and associated costs, etc.<\/li>\n<\/ul>\n\n\n\n<p><strong>Analysis of compressed air requirements<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Given the considerable cost of using compressed air, it is recommended that, before any modifications are made, to determine whether compressed air is indeed the most suitable method for carrying out this task.<\/li>\n\n\n\n<li>Identification of the main characteristics of the compressed air consumption requirement, e.g. pressure level, flow rate, humidity, etc.<\/li>\n\n\n\n<li>Reduce network pressure as far as possible, according to the compressed air requirements (temporary reduction possible depending on requirements)<\/li>\n\n\n\n<li>Identification and elimination of potential leaks in the existing system.
