Pneumatic brake, which use compressed air as a working medium, is the main brake of rail vehicles. The equipment used in the braking system requires sufficiently clean, without water vapour medium to work properly. Removing water vapour from the air prevents condensation and ice formation during winter, which guarantees correct brake operation. For this purpose, adsorption dryers are used in the railways to ensure the required pressure dew point value. This article includes an overview of available compressed air drying methods, the results of calculations and bench test of the dryer prototype developed at the Institute. Assumptions and requirements for the device intended for use in railways are based on European standards and UIC cards.
