The SIRAX series represents the climatic-altitude testing solution within the DOT range, designed to perform combined environmental tests involving temperature, humidity and pressure, with simulation of high-altitude operating conditions up to 45,000 metres.
Each chamber is designed and configured according to the required test conditions, the dimensions and characteristics of the test specimens, thermal loads, target pressure levels and the specific requirements of the application.
Coordinated control of temperature, humidity and pressure makes it possible to reproduce real or extreme environmental conditions, ensuring high levels of precision, stability and repeatability during both static and dynamic test cycles.
is designed to ensure:
- customised design and configuration;
- combined control of temperature, humidity and pressure;
- high-altitude simulation up to 45,000 metres;
- programming of static and dynamic climatic and altitude cycles;
- coordinated management of temperature and pressure variations;
- high stability and uniformity of test conditions;
- precision and repeatability of results over time;
- integration with test benches, data-acquisition systems and dedicated equipment;
- configuration of specific interfaces, interlocks and safety devices;
- supervision, data logging and remote management through DOT technology.
It is one of the most advanced solutions within the DOT range, particularly suitable for laboratories, testing centres and research and development departments operating in the aerospace, defence, avionics, energy, advanced electronics and scientific research sectors.
The customised design allows each chamber to be configured according to the required temperature, humidity and pressure ranges, parameter change rates, thermal loads, applicable standards and the specific characteristics of each project.
