Small Climatic Chamber

The ACE Small Climatic Chamber (SCC) is a dynamic testing space suitable for many different sectors. Due to its broad range of climatic capabilities, it is ideal for test factors such as temperature, humidity, and precipitation. The ACE facility is expertly designed to connect our primary climatic chambers through an inter-chamber door. This permits the insertion of a test bench to create a 'three-chamber' mode that includes the SCC, Large Climatic Chamber (LCC) and our Climatic Aerodynamic Wind Tunnel (CAWT). 


ACE's climatic chambers are suitable for many different sectors. Any product, component or idea that needs climatic validation or testing will find significant value in this chamber. 

Examples of tests conducted in the Small Climatic Chamber include:

  • Cold or hot starts for vehicles
  • Human trial tests
  • Humidity and moisture testing
  • Material testing and product validation in extreme temperatureChevy in Small Climatic Chamber

350 kW DC Fast Charger

ABB Fast Charger in SCC

ACE recently introduced the 350-kilowatt, 500-amp modular DC Fast Charger, which permits faster charging with the capability to operate in a temperature-controlled environment in three of its five chambers, including the Small Climatic Chamber. As the future of the automotive industry progresses, ACE provides OEMs access to a world-class research facility that will actively assist in guiding this sector towards the development of electric vehicles.

Precipitation Testing

Transformer and Rain Rig in SCC

The precipitation capabilities at ACE are limitless. We have the equipment to make and validate various forms of precipitation and we have the tools and techniques necessary to understand and characterize it. Our configurable system allows us to match any testing requirements.
