Take advantage of a unique test facility were companies can test and validate the performance, reliability and robustness of large and heavy wind turbine equipment up to 150 ton under extreme climatic conditions from arctic cold conditions (-60 °C) to desert heat (+60 °C). 
This unique test infrastructure has been tailored to the needs of the wind power industry, embedded in the services offered by Sirris.

The large climate test chamber and its associated testing services have been designed with a number of unique features, in order to facilitate the needs of the wind power industry. Wind turbines are currently installed globally – sometimes in harsh climatic environments such as cold and icy climates (Scandinavia, China, Russia, Inner Mongolia, China,…) or in hot and tropical environments (Middle-east, Australia, South-America,, …). To guarantee optimal performance of wind turbine components, even in the most extreme climatic conditions, the survival capabilities and operating limits of prototype machinery needs to be tested by the use of climate chambers for design validation purposes or certification purposes. 

Extreme temperature levels from -60 °C to +60 °C, temperature cycles, humidity up to 95%RH, solar infrared heat between 10 - 950 W/m² and icing conditions can be tested in a controlled environment. Unique feature is the ability to test large and heavy machinery up to 150 ton in the 10.6 m x 7 m x 8 m large climate chamber. The large climate chamber has been installed at a break-bulk terminal in the Port of Antwerp, enabling easy water, train and land logistics and quay handling of the targeted test specimens. 
  
Summary of features of the large climatic test chamber:

  • Dimensions: 10.6 m x 7 m x 8 m
  • Capability to test >150 ton equipment 
  • Temperature range: -60 °C to +60 °C
  • Thermal cycling possibilities
  • Thermal camera to monitor test campaign in extreme temperatures
  • Humidity testing possibilities between 5%RH to 95%RH
  • Solar infrared-heat test possibilities between 10 to 950 W/m² (3 m x 3 m array)
  • Large cooling capacity for heavy equipment 
  • Ice-spray testing possibilities 
  • Cold start-test-up bench for gearboxes available (10 kNM break-away torque)
  • Flexible power set-up 50 Hz/60Hz up to 10 MW for electrical testing load testing

The climatic test facility is specialised in the testing of wind turbine components and integrated sub-assemblies, such as wind turbine drivetrains (gearboxes, generators, main bearings, journal bearings, …), transformers (liquid filled or cast resin), power convertors, pitch & yaw systems, and hydraulic systems in general. Digital twin methodologies can be tested also by the use of the climate chamber. 

A specific focus of the testing facility can be found in the testing of cold-start-up sequences, lubrication effects in low temperatures, cold climate and winterisation effects, and the effect of icing conditions on large equipment. Ice detection systems, anti-icing (coatings) and de-icing systems are also tested in the facility.

  • Cast resin transformers testing ; class C1 (-5 °C) ; C2 (-25 °C) ; C3 (-45 °C); C4 (-60 °C)
  • NEN-EN-IEC 60068-2-30 (damp heat)
  • ISO 19897 (conditions of icing tests related to shipbuilding & marine structures)
  • Thermal shock test according IEC-60076-11 / GOST-R 54827
