Low Air Pressure Temperature Altitude Chamber

This temperature altitude chamber recreates atmospheric pressures equivalent to altitudes up to 30,000 meters while simultaneously controlling temperature across a wide range from –40°C to +150°C. The combined stress environment allows engineers and researchers to evaluate structural durability, electrical reliability, insulation stability, thermal performance, and safety risks under simulated real-world operational conditions.The Low Air Pressure Temperature Altitude Chamber is widely used across aerospace engineering, aviation electronics, UAV systems, lithium battery depressurization tests, automotive modules, military equipment, high-altitude packaging, and scientific research applications.

Products used in aircraft, satellites, military equipment, and mountain‑top installations are continuously exposed to reduced air pressure and fluctuating thermal conditions. These factors can cause material fatigue, insulation failure, swelling, leakage, fire hazards, and unpredictable behavior.

Pressure-induced Mechanical Stress
Reduced air pressure can cause deformation of housings, seals, and internal materials.

Electrical & Insulation Failures
Low pressure reduces dielectric strength and may trigger corona discharge or insulation breakdown.

Thermal Response at High Altitudes
Heat dissipation weakens; temperature gradients increase; components overheat more easily.

Battery Venting & Electrolyte Expansion
Lithium cells may swell or vent at high altitude due to internal pressure imbalance.

LIB industry's altitude simulation chamber makes it possible to identify hidden risks early, optimize designs, and ensure compliance with international aerospace and reliability standards.
