How IMI Norgren Compressed Air Filters Helped Avoid Costly Downtime on a UK train fleet
How IMI Norgren compressed air filters helped avoid costly downtime
Discover how IMI Norgren filters helped reduce water in essential train airlines – and win a race against time and freezing temperatures.
Freezing temperatures put downstream components and systems at risk
Water in the compressed air system can cause major problems for UK railway vehicle manufacturers.
Once water, oil, and particulates enter a train’s compressed air system, they begin causing damage quickly. Both water and oil can degrade key components and, over time, cause them to fail.
But the problem multiplies rapidly once winter arrives; as temperatures drop, the water freezes and blocks downstream components and systems completely. That’s why preventing water from entering the system is a priority for most train manufacturers.
Depending on the size of the train depot, trains are sometimes left outside over the winter, unshielded from the elements. This increases the chance of frozen components and significant damage to systems, resulting in costly maintenance and out-of-service fines.

On the case fast – before the winter chill arrived
By working with us, our customer had access to a team of engineers with over 130 years of combined experience in both the rail industry and leading IMI Norgren products – some of whom were on-site to assess the problem within a day of receiving the customer call.
Since speed was of the essence, our team recommended that a series of compressed air filters would be the fastest way to reduce the amount of water in the airline and keep the trains running smoothly.
Thanks to our team’s flexibility and rapid supply chain, the equipment was on site and ready for installation before temperatures in the UK had a chance to drop below freezing. The result? More reliable vehicles, fewer maintenance headaches, and major costs saved.
