2. Ambulatory Room

General Characteristics The ambulatory room allows participants to be medically examined during tests. It can also be used to evaluate small or medium-sized objects at high altitudes and non-extreme temperatures. The room has a line of sight between the control room on one side and the test chamber on the other via pressure-tight windows.nestre a tenuta di pressione.

Internal dimensions

4.5 m × 2.8 (L × W)
Maximum simulated altitude 9.000 m ± 10 m ( ~ 30.000 ft)
Maximum Rate of Climb (ROC) 6 m/s (~ 1.180 ft/min)
Minimum Rate of Climb (ROC) 0,1 m/s (~ 20 ft/min)
Temperature Range 20...30°C ± 1°C
O2 level control 6...20.9% ± 0.1%

3. Control Room

General Characteristics The control room contains the control unit for the chamber and its technological infrastructure. The operators set test parameters or execute automated programs for temporal variation of the parameters according to the test’s specifications. A data acquisition system records the climatic and operating parameters. The test chamber is visible to the control room via three large pressure-tight windows. The two environments are connected by a "pass-through" for the exchange of small objects (for example blood samples, tools, etc.) that avoids use of the compensation chamber.

4. Airlock & Restroom

General Characteristics The airlock (compensation chamber) allows entry and exit from the pressurized test chamber. The airlock has a restroom with sink, shower and toilet for use during testing. Rapid depressurisation is also possible in the airlock, which simulates the ascent rate typical of air rescue operations in the high mountains.

Maximum Rate of Climb (ROC) 14m/s (~ 2.750 ft/min)
Minimum Rate of Climb (ROC) 0,1 m/s (~ 20 ft/min)
Temperature Range 20...30°C ± 1°C
O2 level control 6...20,9% ± 0,1%
