Standards
WHO Principles Require:
Long-term stability testing conditions at 25°C/60% RH humidity.
The 40°C/75% RH humidity standard for 6-month accelerated testing is primarily applied in the pharmaceutical industry's stability testing systems, simulating environmental climate conditions including temperature, humidity, and light exposure.
Features
1.Modular Structural Integrity: The lab utilizes a unitized assembly design, allowing you to expand the internal volume or relocate the facility with minimal effort as your production scales.
2.Advanced Airflow Design: By employing a side-top air supply and side-bottom return principle, the system eliminates dead zones, ensuring that even a fully loaded room maintains exceptional temperature and humidity uniformity.
3.Precise Control Algorithms: You benefit from a micro-integral PID control system that coordinates cooling, heating, and humidification to prevent parameter overshoot and ensure rapid recovery after door openings.
4.Regulatory-Grade Monitoring: The high-sensitivity PT100 sensors and dual-mode (program/constant) operation allow you to meet the most stringent ICH stability protocols without manual intervention.
5. Safety Suite: The system includes multi-level protection against over-temperature, low water levels, compressor over-pressure, and phase-sequence anomalies, ensuring 24/7 unmanned operation safety.
