Case Study

A New Rail Dryer System and Expert Support for European train operator

June 5, 2025

The goal: Reduce time spent on maintenance with sturdier, longer-lasting equipment

To keep a train running reliably, every component needs to work at its best – especially a crucial component like a compressed air dryer, which extracts water vapor to prevent damage to major downstream systems and components.

Train operators need to know that their suppliers provide products that guarantee a high level of performance and will be there to support them fully.

Expert support and outstanding technology help train operator reach its goals

A European train operator was looking for a partner who could offer a combination of precise, reliable technology; proven experience in the rail industry; and expert technical support – and decided to conduct trials using IMI Norgren equipment.

From the beginning, we were ready to go further to guarantee results for the train operator. To begin with, their engineers travelled out to the train depot to install the IMI Norgren Adsorbent Media Tube (AMT) Dryer System on several trains.

The AMT Dryer System is a tried-and-tested, fit-and-forget system – compact, flexible, and designed to last over 10 years. This is equivalent to five times that of a standard membrane dryer thanks to the superior, patented design.

But we also added a feature designed specifically for this train operator – a dew point sensor that would monitor the performance of the equipment and alert the engineers if the dew point fell below optimum levels

That outstanding technology was backed by a team of expert engineers, dedicated to ensuring the train operator saw the best results. Once the initial dryers had been fitted, the engineers monitored their performance closely and listened to feedback from the customer. After three years, the results were impressive, so the train operator asked us to install the dryers on the rest of its fleet. .

We have continued working closely with the train operator for almost a decade after the first installation – building a partnership that showed they had the support it needed to run its trains with complete confidence.
