Details

TD and UD series are aimed at the adaptability test of equipment or equipment in the aerospace field under the combined action of altitude, temperature and humidity in the air or at high altitude.

This series of products can meet the comprehensive tests of damp heat, air pressure and temperature, and can be equipped with rapid pressure reduction function. It meets the rapid pressure reduction standard of 75.2kpa ~ 18.8kpa ≤ 15s in gjb150.2a-2009, can also meet the explosion pressure reduction test of 0.1s, and can also be equipped with rapid cooling function and vibration function. We provide 250L, 500L, 1000L and 2000L standard volume series products, and can customize non-standard volume and walk-in products according to customer needs.
