A constant temperature and humidity chamber for the long, steady tests that cannot be interrupted: stability studies, shelf-life testing, material conditioning and bioproduct storage. It holds 0 to 100 °C and 20 to 98 %RH with ±0.5 °C fluctuation, while a variable-frequency compressor, thick insulation and a water recirculation system keep running costs and refills low. Four sizes from 150 to 1000 L, with a 2-year warranty.
The stable damp-heat working zone
Temperature runs from 0 to 100 °C. Where temperature and humidity are controlled together, the chamber holds the coloured zone steadily for weeks. The three markers are the ICH stability conditions many labs run every day; all three sit comfortably inside.

Choose a size
Same range, controller and protection on every size. Front elevations drawn to the same scale.
Ready for long-term stability studies
Typical ICH conditions for drug substances and products, all inside the controlled zone, held for months at low running cost.
Real-time stability at standard storage conditions.
When accelerated results show a significant change.
Faster degradation for early shelf-life estimates.
Conditions as commonly specified in ICH Q1A(R2). Your protocol defines the exact conditions and durations.
Water recirculation: weeks without refilling
Condensate and unevaporated water are collected and pumped back to the humidifier reservoir, for more than 80% better water utilization, less DI or RO water, no external drain line and unattended running for weeks or months.
Engineered to run cheaply for months
Energy-saving design and the details that make long tests simple.
Variable-frequency compressor
Output follows the load instead of cycling at full speed, for steadier control and lower energy use.
Thicker insulation
Low-conductivity insulation reduces the work the heater and compressor must do.
Automatic water refill
A recirculation tank feeds the humidifier automatically.
Optimized air duct
Even airflow for better temperature and humidity uniformity.
SUS 304B interior
Acid- and corrosion-resistant stainless steel that wipes clean.
R290 refrigerant
A natural refrigerant, in an air-cooled hermetic system.
Touch screen, PT100
Clear touch control with a platinum resistance PT100 sensor.
100 mm test hole
Run cables to powered samples during the test.
Low power, standard sockets
Current draw is low enough for ordinary lab circuits.
Safety protection
The chamber protects itself, your samples and your lab.
Show all 4 safety protections
- Compressor overload protection
- Humidification heater dry-burn protection: power is cut when reservoir water is too low
- Over-temperature protection: heating, and if needed cooling, shut down
- Electrical short-circuit protection

Questions buyers ask
Straight answers before you order.
Can it run ICH stability conditions?
Yes. 25 °C / 60 %RH, 30 °C / 65 %RH and 40 °C / 75 %RH all sit inside the controlled temperature and humidity zone.
Which humidity is possible at which temperature?
See the control range chart: humidity is controlled from 15 to 85 °C, up to about 90 %RH; the minimum humidity rises at lower temperatures. Outside the zone, ask our engineers.
How often do I need to add water?
Rarely. The water recirculation system reuses condensate and unevaporated water and refills the humidifier automatically, for weeks or months of unattended running.
Which voltage should I order?
Every size is offered in 110 V and 208–240 V versions. The 150 L and 250 L draw 6.8 A at 220 V; the 500 L and 1000 L draw 11.4 A at 220 V.
