Technical assistance services, corrective and preventive maintenance. Customer training.

Design, manufacturing, and service of HVAC systems for all types of railway applications: High Speed (e.g. TGV2020/RGV in France, Talgo Renfe F070 and Zefiro in Spain, Zefiro in Italy, East Midlands in UK, Velaro Russia and Velaro Novo platform), Metros (e.g. Brussels, Helsinki, Milan, Montreal, Santiago and Sanying), Regional/Commuter trains for different operators in Belarus, France, Germany, Italy, Netherlands, Luxemburg, Poland and UK, LRVs (e.g. Torino) as well as Passenger Cars for Denmark, Egypt and Germany. Modernization of trains in service (France, Netherlands, Poland, Portugal, Spain, United States). Air Distribution, Filtration and Purification System clean[air]. Refrigerant replacements adapted to the new regulations regarding F-Gases.



FRENOS Division: Brakes and Air Production Area: New air production modules, with intelligent control allowing to minimize energy consumption, noise emission, weight and size of the equipment due to the possibility of varying the rotation speed in an intelligent way. iCom monitoring systems providing the capability to know, in real time, the status of different equipment of a fleet of vehicles and to define a maintenance based on the condition. New design of the axle disc for freight wagons, 60 mm thinner and 45 kg lighter than the traditional one. ESRA Evolution electronics based on the tested ESRA brake control system and incorporating new microcontrollers; this system increases the integration interfaces and allows the SW to be quickly and easily updated. New MGS3 anti-skid electronic system, which minimizes brake distances when the adherence is very low. // Doors Systems Area: Development of doorsystem RLE as continuation of the RLS product family, available for sliding plug doors and sliding doors and allowing additional optional features, like an improved central cut out and lower weight and power consumption.

Merak: Merak is leader in the market for railway climate control systems, including their migration to refrigerants with low GWP (Global Warming Potential) with alternative and natural refrigerants.
Furthermore, modular solutions have been developed which allow adaptation of a design to different climatic zones and the possibility of responding to different requirements like adaptation to High Speed, integration of air extraction systems, etc. The resulting systems guarantee maximum comfort and reduce energy consumption by between 10% and 30%.
Development of the innovative clean[air] technology based on different phases of air purification and filtration which guarantee a clean and safe environment for the travelers in the train.
Included in this technology is the creation of the revolutionary Long-Life Filter, which lasts 4 times longer than other conventional filters and so contributes to a substantial saving in maintenance cost and spare parts, as well as less waste generation.
