After speaking to both managers, we were confident that Expel would offer a permanent solution to the problems occurring at this site.
Expel offers a revolutionary approach to compressed air filtration and is unlike anything else currently on the market. EXPEL is a high efficiency compressed air filter which uses computational fluid dynamics to continually pass all liquid water, oil emulsion fluids and solid particulates down to 1 micron through the unit and into an AVG Auto Drain. This means that the performance of Expel does not drop with use and remains 99.999% efficient and does not require any replacement filter elements or maintenance to operate. This makes Expel the perfect solution to the problem of freezing water in compressed air lines, as Expel continually ensures there is never enough water in the lines to freeze.
Traditional compressed air filters are not as efficient as Expel because they contain internal elements that retain the water droplets they collect in an absorbent element, which will become less effective as they are used or can be easily overwhelmed with the water if there is a large volume. When this problem occurs, water can freeze in the compressed air lines resulting in the problems this site was experiencing.
