Cooling Systems for Locomotives, Railcars and Special Vehicles

Reliability Wherever it's Needed.

Cooling Systems for Locomotives, Railcars and Special Purpose Vehicles. You Can Depend on Them.

Locomotives, railcars and special vehicles are frequently in continuous use. The same can be said about our cooling systems. Regardless of the type of drive - there is always a lot of heat. Our reliable cooling systems disperse this heat in a controlled manner. Even under extreme conditions. In all performance classes by means of a variable-speed fan drive. You can depend on it.

      SilentVent – Improvement that Comes Quietly

      With the new axial fan, we have improved the aerodynamic characteristics significantly. At the same time, we comply with the strict exhaust gas directives easily.

      Great Input Power Requires More Cooling Capacity.

      The completely new axial fan provides it. It simultaneously lowers the noise level of the cooling system. The geometry of the new fan has been improved decidedly, and air flows in and out optimized as regards noise generation.

      Nanocoatings for Cooling Systems – Ensure Outstanding Performance.

      Nanotechnology improves corrosion protection. It also helps to keep cooling equipment clean.

      In order to ensure that our air-conditioning equipment also functions reliably in critical climate zones or in chemically aggressive surroundings, we now use a completely new coating system based on nanotechnology. This makes it possible to install smaller coolers that provide the same performance and weigh less. Less accumulation of dirt means longer maintenance intervals. Smaller cooling systems reduce vehicle weight – and thus fuel costs. Good for the operator and the environment.
