Large Climatic Chamber
This chamber is unique due to its exceptionally long test section, accommodating vehicles as large as an articulated bus. It also contains a Mustang 1,000 horse-power chassis dynamometer and a solar array to simulate the sun. You also have the option of connecting to the Small Climatic Chamber through an inter-chamber door, which permits the insertion of a test bench to effect a 'three-chamber' mode that includes:
- Climatic Aerodynamic Wind Tunnel
- Large Climate Chamber
- Small Climate Chamber
Sectors:
A vast number of sectors can utilize ACE’s climatic chambers. Any product, component or idea that needs climatic validation or testing will find significant value in this chamber.
Testing examples:
- Cold or hot starts for vehicles
- Engine tuning (on Mustang dynamometer)
- Heating, ventilation and air-conditioning (HVAC) testing
- Physiological/cognitive human trial tests
- Product validation in extreme temperatures or solar conditions
