The site had both refrigerant dryers and conventional compressed air filters installed as an attempt to solve the problem of moisture and solid particulates in compressed air lines. However, these solutions were not getting rid of the problem which was exemplified through the large numbers of mac valves which were being damaged by moisture and were in need of constant replacement.
After installing Expel, its effectiveness was noticed very quickly as the maintenance team found they were no longer having to replace moisture damaged mac valves. So why has Expel succeeded where other solutions have failed? – The answer is simple. Expel has a unique patent protected design which 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 the more they are used and unlike Expel, 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, and the compressed air is exposed to temperature changes which would fall below the dryer dewpoint. Expel can still operate in very low temperatures, making it a far more reliable solution for the site.
These outstanding results did not go unnoticed by Mark Gibson’s team and have since attracted 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 as a matter of urgency to eradicate the problem of moisture from compressed air lines as soon as possible. This site has since ordered units, and we are very excited to hear about the results in due course!
