Gardner Denver Transport - Compressors and Compressed Air Supply Units

For over 30 years, Gardner Denver Wittig has been known as a supplier of compressors and complete compressed air supply units for light and heavy railway vehicles, metros, electrical multiple units, locomotives, trams and trolleybuses. Compressed air supply units consist of a compressor, a control system and an air treatment unit, all mounted in a frame, with defined interfaces and ready for installation.

We are your competent partner for all issues concerning compressed air supply for new rolling stock and all refurbishment projects. Our project engineering and after sales service take care of all projects from beginning to end.

An ISO 9001 quality management system, certification according to DIN 6700 and the use of state-of-the-art engineering tools such as FEA, FMEA, RAMS and LCC analysis ensure high standards. Additional extensive shock vibration and temperature tests confirm the robust design, suitable for all rough environments.

COMPRESSOR APPLICATIONS IN PUBLIC TRANSPORT SYSTEMS

Almost all of the auxiliary devices of public transport systems are operated by compressed air. Examples include: suspension, brake system, sanding, windscreen wipers, door operation, pantograph and wetting of wheels. Wittig ROL M compressors are especially designed to ensure that all these devices are available on demand and also under extreme conditions.

INNOVATIVE COMPRESSORS AND COMPLETE COMPRESSOR PLUG-IN UNITS

Based on a wide knowledge and decades of experience regarding all the specific requirements of compressed air supplies for railway applications, Gardner Denver Wittig has designed the Wittig ROL M.
