The Darwin Chambers pre-engineered walk-in stability rooms are designed to reduce project timelines, simplify installation, and save up to 30% compared to fully custom-engineered solutions. Delivering precise temperature and humidity control that exceeds ICH performance requirements, it’s an ideal solution for regulated environments requiring dependable environmental storage.
Built Around Proven Stability Conditions.
Rather than beginning every project from scratch, these stability rooms have been engineered around one of the most requested ICH stability room configurations.
Standard Environmental Conditions
- 25°C to 40°C temperature range
- 60%RH to 75%RH humidity range
- Temperature control at sensor/set point: ±0.2°C

Technical Specifications & Additional Details
Chamber Operation & Environmental Performance
These rooms are designed to deliver precise and repeatable environmental conditions for regulated stability testing applications.
Chamber Operation
- Model Number: ICH-G1HD-10X10
- Chamber Temperature Range: 25°C to 40°C
- Chamber Temperature Control at Sensor/Set Point: ±0.2°C
- Chamber Relative Humidity Range: 60%RH to 75%RH
- Chamber Humidity Control at Sensor: ±0.3%RH
Temperature and relative humidity specifications assume standard operation in a controlled ambient environment of 72°F ±8°F and a dew point at or below 50°F.
Demonstrated Environmental Performance
Performance mapping of similar installations, conducted using 24 Type “T” thermocouples and 8 Rotronic HygroClip sensors in conjunction with a Kaye 2000 Validator, has repeatedly documented environmental uniformity better than:
- ±0.4°C temperature variance
- ±0.7%RH humidity variance
These measurements were recorded throughout the storage space over a 24-hour period. Documentation demonstrating performance exceeding ICH guidelines is available upon request.
Cold Room Operation & Environmental Performance
The Cold Room Special is designed to deliver precise refrigerated storage conditions for regulated pharmaceutical, laboratory, and research applications.
Chamber Operation
- Model Number: LAB-G1NN-10X10
- Chamber Temperature Range: 2°C to 8°C
- Chamber Temperature Control at Sensor: ±0.2°C
Cold Room Operating Conditions & Performance Notes
Performance specifications assume standard loading, adequate airflow, and operation in a controlled ambient environment of 22.2°C ±4.4°C with a dew point at or below 11.1°C (22.2°C / 50% RH). Extended operation at some set points below 4°C may require slight defrost tolerances.
