What is an Altitude Test Chamber?

The Altitude Test Chamber, also referred to as the Low Pressure Test Chamber or Vacuum Environmental Chamber, is a testing system that helps recreate the atmospheric conditions pertaining to higher altitudes by decreasing the air pressure in the chamber. Moreover, it can control temperature and humidity accurately to simulate the actual environmental conditions under which the aviation and aerospace operations occur at the high altitudes while different processes like flying, and transporting can be carried out.

Such types of chambers are used by manufacturers to check whether products are capable of working properly in such low-pressure conditions since cooling effectiveness, insulation, electrical operations, and material properties can change dramatically.

Psychometric chart

Note:

1) Only standard range is part of the scope

2) If optional low rh is required then additional charges will be incurred due to addition of dehumidifier

Note:

The performance values provided are tested conditions at 25-32°c, humidity with ≤65%rh, rated voltage under empty condition.
Only DM water to be used while running humidity test.
The performance values are based on IEC 60068-3-5.
Noise level measurements are carried out in an anechoic chamber at a height of 1.2m from the floor and 1m from the front panel (ISO 1996-1:2003 a weighted sound pressure level).
Chamber to be placed in well-ventilated room ambient condition (25-35°c).
