Oil-free compressor solutions for railway applications
Dürr Technik is your specialist for oil and maintenance free piston compressors. Especiallyin rail transport, it is importantthat theproducts meet the highestdemands ofreliabilityand durability. Safety is the first priority. Therefore original equipment suppliers have been utilising our high-quality and compact product solutions for many years.
Eachtrainhas its own characteristicswithindividual requirements.For this reason,together with our customerswedevelop the optimalsolutionand manufacture tailor made products.
Oil-free auxiliary compressor applications for railway vehicles:
Wheel fl ange lubrication
Toilet evacuation systems and toilet door control
Signal horn activation
Support of the compensating air for service vehicles
Receiver systems for sand fi lling
The following examples show product solutions that we have developed exclusively for respective customers:
1. Supplying individual system solutions
For raising the pantograph, we manufacture complete auxiliary air compressor systems as one package, customized to meet the individual customer requirements.
2. Multi-functional auxiliary air compressor systems
This system is usedforseveralapplications.It provideshigh quality compressed airforsanding,flange lubrication, hornandtoiletdoor control.Tests,such aselectromagneticcompatibility according toEN50121-3-2, vibration andshock test according toEN61373, salt spraytest etc.,weresuccessfullycompleted.
Innovative oil-free compressor technology with key advantages:
Oil-free means trouble-free There is no need for checking the oil level and changing oil. The costs for fi lter and disposal of waste oil can be saved. Maintenance is virtually unnecessary. Functions are not impaired by oil vapours.
Low LCC The high quality materials used, ensure minimum amount of wear and therefore is a guarantee for an extremely long lifespan of the components and a very little demand for spare parts.
Innovative motor concepts Customized especially for railway application.
XT-Models Available with up to 20.000 operating hours lifetime.
Low noise level and noise transmission
Extremely reliable Oversized components and keeping the tightest tolerances are major aspects of our design. These are tested and verifi ed under the harshest conditions.
Since 2009 Dürr Technik has been certified according to IRIS
