Large Altiude test chamber|Sanwood Technology One-stop Low Pressure Test Solution

Sanwood Technology's Large Altiude test chamber is a comprehensive test equipment that specializes in simulating high altitude, plateau, near-space and space environments.Through the coordinated regulation of the high-precision air pressure control system (normal pressure ~ 80.0kPa) and the wide temperature and humidity range (+25℃ ~ +50℃), the multi-dimensional coupled extreme environmental conditions such as low /high temperature, low pressure, humidity and heat are truly reproduced.

Sanwood Technology's Large Altiude test chamber is widely used in aerospace, semiconductor manufacturing, automobiles, military research, low-altitude economy and other fields to test the pressure resistance, sealing performance and reliability of electronic and electrical products, materials, components, equipment, etc. under low temperature, high temperature and low-pressure environments, helping to test product performance under extreme conditions, shorten test time and improve product reliability.

Equipment Features

Meet the test standards, safe and reliable；

Pressure control accuracy：Through high-precision vacuum pump and pressure sensor, stable control of ±0.5% is achieved.

Rapid vacuuming：The target air pressure can be reached in a short time (such as 10 ~ 30 minutes), improving the test efficiency.

Multi-system collaborative design

Cascade Refrigeration System：Adopt two-stage or cascade compressor refrigeration to ensure ultra-low temperature stable operation.

Heating balance system：PID regulated electric heater cooperates with refrigeration system to achieve rapid temperature switching.

Air pressure-temperature coupling control：Independently control air pressure and temperature to avoid mutual interference and ensure test accuracy.

Sealing design：Highly sealed box (such as silicone sealing strips) and anti-condensation technology to ensure airtightness under low pressure
