In the AEROSPACE TESTING INTERNATIONAL magazine of March 2016, you can read this Climats bulletin board :
ENVIRONMENTAL STRESS SCREENING CHAMBERS MAKER
Thermal chambers are necessary to achieve the aerospace standards MIL STD 810G or RTCADO160.
To simulate the environmental stresses that aircraft components need to survive, a wide temperature range is required and the rate of speed change (average or linear) must occur very rapidly.
Electronic components might be very sensitive to humidity migration, which is why any environmental chamber must ensure a perfect control of humidity to prevent damage to the components under test.
To support aerospace testing applications, Climats designs standard and customized chambers, enabling engineers to set up and achieve demanding test standard profiles with a high accuracy (+/- 0.1°C on a soak cycle) and very high traceability with measurement sampling every second.
Model 585 VRT 70/22 is a good example of the high-performance solutions manufactured by Climats. Designed for a major aircraft manufactured, this chamber reaches an average temperature change speed of 20°C/min from +100°C down to -55°C while loaded with 100kg of electronics boards that can generate 1kW of heat dissipation load.
The embedded control and HMI (human machine interface) software suite, SPIRALE 3, is a multi-tasking Windows-based system displayed on a 15in touchscreen. This operates realtime humidity measurements managing the air dryer, while communication with the customer's test bench.
With these Climats ESS chambers, the aircraft manufacturer can qualify a complete electronics system, fulfilling the desired standards and achieving the highest quality levels for testing.
