Our wide range is constantly being revised and expanded. Our team will provide you with expert and comprehensive advice on all ventilation issues.
Customers do not simply buy air conditioning/ventilation technology off the shelf from us. In addition to the products of numerous manufacturers of ventilation assemblies and devices, we also supply fans from our own production. Our company specializes in the design and manufacture of railway-compatible blowers for mobile use in rail vehicles.
According to individual customer requirements, we develop and manufacture customized cooling fans that are adapted to the special features of railroad technology and meet the requirements of high-performance motors and the increasingly compact electronics in rail vehicles, even under extreme conditions.
In addition, we have succeeded in opening up various areas of application in energy technology for the use of environmentally friendly, performance-adapted fans for cooling generators, stationary converters and large motors, which have already proven their worth in switchgear and wind power plants. We also design and realize custom-made products according to your special requirements.
