Compressed Air Dryers

Compressed Air Dryers

Our revolutionary air dryers with patented AMT technology offer outstanding levels of performance and reliability delivering a step change in compressed air applications in the rail industry.

With a life span of ten years - significantly more than even the best performing alternatives - our patented Adsorbent Media Tube (AMT) dryer advances significantly over both desiccant and membrane systems.

Vibration resistant and suitable in both horizontal and vertical installations, the result is a product which dries better than any current solution.

  • Service life of up to 30,000 hours (ten years)
  • Compact and flexible design which can be mounted horizontally and vertically
  • Typical dew point suppression of 40°C

We talk extensively to maintenance professionals and work closely with rail engineers to answer the questions they ask. That means we offer customised, practical solutions to the metro, intercity, high-speed, freight and permanent-way rail industries.

New York City Transit Case Study

NYC Transit engineeers noticed that moisture in compressed air was causing mechanical problems on subway cars downstream. They saw the performance of OEM pressure swing dryers gradually decline.

As opposed to conventional desiccant beads, which when water-saturated cannot be regenerated, our AMT dryer uses a polymer to form hollow tubes impervious to moisture.

This design delivers higher moisture uptake and faster purging, without degrading the dryer media, improving both performance and longevity.

We designed a test consisting of a multi-stage filtration system that removes particulate contaminants as well as the water vapour removed by the AMT dryer.

NYC Transit replaced the conventional pressure swing dryers with these AMT test units on a complete train and ran them under normal conditions. After 12 months of operation in the extreme temperatures and humidity of New York city, test results showed that air leaving the dryerswas as dry as when the system was first installed, with no decay or reduction in water removal capabilities.

Watch the video to see how a multi-stage filtration system incorporating our AMT dryer delivers a continous supply of clean, dry compressed air.
