Key Performance Features
Temperature Control System
The chamber utilizes Balanced Temperature Control (BTC) technology combined with PID auto-tuning algorithms. This configuration maintains temperature stability within ±1°C fluctuation range and ±2°C uniformity across the testing volume.
Construction Materials
- Inner chamber: 1.2mm stainless steel construction for corrosion resistance
- Exterior housing: 1.0mm cold-rolled steel with powder coating
- Insulation: 100mm thick high-density rock wool reduces heat loss by up to 15%
Air Circulation Design
The forced closed-loop airflow system employs a high-temperature resistant stainless steel centrifugal fan. This design ensures uniform heat distribution and reduces temperature gradients within the chamber.
