Regenerative Desiccant Dryers

The market for high pressure regenerative desiccant dryers is small and specialised, requiring a high level of customised engineering combined with highly skilled small batch manufacture. L B Bentley has spent over thirty years developing these qualities.

Bentley dryers are frequently packaged together with up to six stages of pre and after filtration (of our own manufacture) to meet the highest standards of air / gas quality. They are built to give many years of reliable and safe operation under the most demanding working conditions.

Bentley dryers are used extensively for many applications including Defence Standard ‘Pure Air’ for thermal imaging, medical and special gases, air blast circuit breakers, ships systems, waveguide dryers, dockside services and many other applications.
