Applications

1. Automotive R&D Testing

Cold Start Test: Verifies engine starting performance at low temperatures (e.g., -40°C), requiring ≤3 successful starts with a start time ≤15 seconds.

Thermal Equilibrium Test: Simulates high-temperature (+60°C) and high-humidity environments to evaluate the stability of air conditioning systems and cooling components.

Material Reliability: Assesses the aging resistance of body coatings and rubber seals under temperature-humidity cycling conditions.

2. Other Applications

Extendable for environmental reliability testing in aerospace, large home appliances, and other industries, supporting composite environment simulation including low atmospheric pressure (1 kPa to atmospheric pressure).
