The site had refrigerant dryers and conventional compressed air filters installed to solve the problem of moisture and solid particulates in compressed air lines. However, these solutions did not eliminate the issues, exemplified by the large number of valves damaged by liquid water and needing constant replacement.
After installing Expel, the maintenance team noticed its effectiveness quickly. The maintenance team found they no longer had to replace moisture-damaged valves. So why has Expel succeeded where other solutions have failed? – The answer is simple. Expel has a unique patent-protected design that allows it to continually remove 99.999% of all liquid water, oil emulsion fluids and solid particulates down to 1 micron from compressed air lines. In contrast, traditional compressed air filters contain disposable internal elements that become less and less effective. Unlike Expel, they can never guarantee that these harmful contaminants will not reach critical machinery like optical sorting machines.
Refrigerant dryers were also proving problematic for this site because when the compressed air leaves the dryer, it has to travel a long distance before it reaches the optical sorting machines. Exposure to temperature changes causes the compressed air to fall below the dryer dewpoint, causing moisture. Expel can still operate in low temperatures, making it a far more reliable solution for the site.
These outstanding results were not unnoticed by Mark Gibson’s team and have attracted attention from other sites. For example, Maintenance Supervisor Andrzej Slimak from the Crayford Material Recycling Facility site was so impressed with these results that he asked us to visit his sites urgently to eradicate the moisture problem from compressed air lines as soon as possible. This site has since ordered units, and we are excited to hear about the results in due course!
