1. Large climatic test chamber OWI-LabExtreme temperature testing & wind turbinecomponent validationWind industry is fast expanding in remote areas where To come to this necessity, the infrastructure should bethe turbines need to work under extreme conditions. available to test the behavior and performance of theUsually onshore and offshore wind turbines are designed machines in a wide range of temperatures. The Offshoreto operate in a temperature range from -10C to +40C, Wind Infrastructure Application Lab (OWI-Lab) invested inbut in some locations like for example Finland and such test infrastructure.Mongolia the temperature can even drop to -40C. On In the Port of Antwerp a large climatic chamber forthe other hand, turbines located in for example India can wind turbine component testing in a wide rangesuffer from extreme heat when located in deserts where of temperatures has been built by OWI-Lab. Bothtemperature could reach up to +60C. mechanical, hydraulic and electrical turbine componentsThese inhospitable locations form a huge challenge for like gearboxes or transformers up to 150 tones can bethe machine itself and also for the maintenance and tested in a temperature range from -60C to +60C. Typicalrepair teams. In some cases repair works have to be prototype testing activities in the facility include designpostponed because of temperatures and thereby affects verification testing (DVT), and component validation.the turbine availability and its business case. This is why Dedicated R&D tests will be supported by providingthe industry needs robust and validated components the required auxiliaries like for example a flexible set ofcapable of surviving in extreme conditions in order to be power supplies up to 2MVA and a drive to give speed tocost-effective. rotary parts.

2. Large climatic test chamber OWI-LabExtreme temperature testing & wind turbine component validationMain focusIntended to test and validate large and heavy wind turbine componentsin the field of extreme temperature testing: gearboxes, transformers, yaw-systems, hydraulic units, hydraulic drive trains, Other components fromdifferent industries who deal with large machinery can be tested as well:heavy industry applications; aerospace components, power aggregates, radarsystems, wave & tidal converters,LocationThe large climatic test chamber is embedded in the OWI-Lab test facilitywhich is located in the Port of Antwerp nearby the DP World breakbulkterminal.
