High altitude/low air pressure test chamber

Model

MBS-QY225

Scope of application

The equipment is intended for product reliability and performance evaluation by simulating the products in high altitude and low air pressure environment.

Construction

Size

W (width): 700mm; H (height): 1650mm; D (depth): 1700mm (subject to inner chamber dimensions)

Cabinet

Double-side galvanized steel plate, with surface powder coated

Inner chamber

SUS304 stainless steel (size customizable)

Inspection window

There is an inspection window on the chamber door, with window pane being multi-layer vacuum glass. It has automatic defrosting and the film on glass surface is electronically heated to ensure no frost or condensate forms on glass surface during whichever test.

Pressure bearing mode

Inner chamber is made of quality 5mm thick SUS304 antiskid stainless steel and reinforcing U-steel is fitted around the space between inner and outer chambers to make the designed overall bearing strength exceed 10t/m. Edges of the inner wall is smooth and flat without burrs or dents, making it easy to clean and ensuring no water accumulation during operation.

Air pressure range

11.6kPa-101.3kPa

Air pressure fluctuation

≤5%

Vacuum degree description

1.3kPa (at standard required simulated altitude of 15240m: 11.6kPa; vacuum gauge indicated value: 89.7kPa)

Note: Since atmospheric pressure in the chamber is 101.325Kpa, in order to reduce atmospheric pressure in the chamber to 11.6kPa, you need to remove air pressure of 89.7kPa (calculated according to the standard atmospheric pressure of 101.325kPa) from the chamber, thereby achieving the low pressure environment of 11.6kPa. Now, the gauge indicates negative pressure and when it indicates the negative pressure of 89.7kPa, the low pressure of 11.6kPa is realized in the chamber.
