DANBLE Temperature & Altitude Test Chamber

A Temperature & Altitude Test Chamber (also known as a Hypobaric Chamber) is a specialized environmental testing system that simulates the combined effects of extreme thermal conditions and low-pressure atmospheric environments.

Its primary purpose is to evaluate how products—specifically those in the aerospace, defense, and high-altitude electronics sectors—perform as they transition from sea level to the thin, cold air of high altitudes.

Dual-Stress Simulation

These chambers control two critical variables simultaneously:

• Temperature: Simulating the extreme cold of the stratosphere (down to -70°C) or the intense heat of high-speed friction and solar radiation (up to +180°C).
• Altitude (Pressure): Utilizing heavy-duty vacuum pumps to reduce internal pressure, simulating altitudes from sea level up to 100,000 feet (30,000 meters) or higher.

Why Test Both Together?

Testing under vacuum significantly changes the physics of the environment:

• Reduced Heat Dissipation: In a vacuum, there is less air to carry heat away via convection. Electronics that stay cool at sea level may quickly overheat at high altitudes.
• Dielectric Breakdown (Arcing): Thin air is a poor insulator. Lower pressure increases the risk of electrical "arcing" or "corona discharge" in high-voltage components, such as EV batteries or aircraft power systems.
• Material Outgassing: Low pressure can cause volatile compounds in plastics, adhesives, or lubricants to evaporate (outgas), leading to brittle materials or fogged lenses.
• Structural Integrity: Rapid decompression tests ensure that sealed housings or battery pouches do not swell, leak, or burst when external pressure drops.

Core Applications

• Aerospace & Aviation: Testing flight computers, sensors, and cockpit displays for commercial and military aircraft.
• EV & Battery Research: Simulating air-transport conditions for lithium batteries (meeting UN 38.3 requirements for altitude simulation).
• Outdoor Gear: Testing telecommunications equipment installed in high-mountain regions.
