Climate Chambers for Your Specific Requirements - Tailor-Made Systems
From walk-in climate chambers to climate cabinets with larger-than-average volumes. Your specific requirements can be met and implemented - down to the smallest detail.
Please describe your requirements and our engineers will design your customized system.
What is a climatic chamber?
A climatic chamber, often also referred to as a climate chamber or environmental test chamber, is a device in which an enclosed volume can be set to artificially generated, predetermined temperature and humidity values. In general, several different temperature/humidity combinations can be generated in a climate chamber. Ramp programs can be run in which temperature and / or humidity change fully automated in defined steps at pre-determined times. Chambers are available from desktop units with capacity of only a few litres to walk-in chambers with large volumes.Climate test chambers are used everywhere in industry and research; be it as a cabinet for precisely defined storage conditions, for material investigations, electronic component stress tests, aging tests on components and parts, research on vaccines, growing of nutrient media and many more.
Climate chambers are widely used in many industries. They are used to simulate climatic conditions such as temperature, humidity, pressure, vibration and light intensity. The conditions are controlled or varied according to the test specifications or the user's requirements.
Products and samples are placed within the controlled environment according to defined test specifications that require compliance with certain conditions. Examples are 40 °C / 75 %RH for drug stability and 85 °C / 85 %RH for military component tests. Confirmation that the correct environmental conditions have been achieved is a prerequisite for compliance with the respective standards that can be found in every industry.
The most common application scenarios for a climate chamber include, but are not limited to:
- Pharmaceutical Stability Tests
- Electronic Reliability Testing
- Vehicle Components Testing
- Plant Growth Chambers
- Aerospace / Altitude Testing
- Engine Testing
- Military Equipment Testing
- Sample Packaging Testing
Examples of test specifications:
Type of test | Application | Typical environmental conditions |
ICH protocols (e.g. Q1A) | Drug stability | 20, 30, 45 °C / 60 %RH, 75 %RH |
MIL | Military equipment | 85 °C / 85 %RH |
Technical Features of our Climate Chambers
Climate chamber with dew-point humidity control
How does the dew point control used in our climate chambers work?
The relative humidity in the climate test chamber is adjusted by a tempered water bath. To achieve a relative humidity of 60 %rh at 50 °C, the temperature of the water bath must be kept at a constant 40 °C. This corresponds to the dew point at 50 °C and 60 %rh.
Using this innovative humidity control system in our climate chambers, the environmental conditions can be precisely adjusted and kept very stable.
Climate test cabinets with PID control
Our high-quality temperature and climate cabinets are equipped with PID control. PID stands for proportional, integral and derivative. This control loop mechanism is more powerful than a simple on-off controller because it quickly approaches pre-set parameters such as temperature or humidity without undesirable overshoot and keeps them precisely at default values.
The intelligent PID controller in Kambic’s environmental test chambers ensures a very uniform and stable temperature distribution across the entire test chamber volume and for the whole temperature range.
Peltier-based temperature control for ultra-stable climate cabinets
These cabinets are equipped with a Peltier-based temperature control system, which guarantees fast heating and cooling times while maintaining the highest precision. The ultra stable temperature control and uniformity of our Peltier climate test cabinets of up to ±0.03 °C are unmatched in today’s market.
These Stability Chambers are designed for climatic (environmental simulation), material and stability tests. The Peltier system makes them quiet, space-saving, environmentally friendly and at the same time very economical. Innovative Peltier technology in Kambic’s climate test cabinets enables stable and accurate long-term testing. The tight temperature control between +8 ºC and +55 ºC and the active humidification and dehumidification of 10 %rh to 98 %rh have been optimally chosen for the requirements of stability analysis.
Basing the heating and cooling concept of the environmental cabinets on Peltier elements also convinces with high efficiency, achieving energy savings of up to 90% during the course of a test lasting several months. Because of its vibration-free operation, the constant climate chamber is ideal not only for environmental simulation and long-term material testing but also for the breeding of insects and reptiles.
