What is a climate chamber?

A climatic chamber, often also referred to as a climatic chamber or climatic test chamber, is a technical device in which the temperature and humidity can be defined. As a rule, various temperature/humidity combinations can be generated in a climate chamber or ramp programs can be run in which the temperature and/or humidity change fully automatically in defined steps and times. Climate chambers are available as table-top units with a capacity of just a few liters as well as huge, walk-in climate chambers.

Climatic test chambers are used everywhere in industry and research, whether as a chamber for precisely defined storage conditions, for material tests, stress tests on electronic components, ageing tests on components and parts, research on vaccines, cultivation of culture media and much more.

Chambers for environmental simulation 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 user or test specifications.
Products and samples are placed within the controlled environment according to defined test specifications that require certain conditions to be met. Examples include 40 °C / 75 %RH for drug stability and 85 °C / 85 %RH for military component testing. Confirmation that the correct environmental conditions have been achieved is a prerequisite for compliance with the relevant standards that apply in each industry.

The most common application scenarios include:

• Pharmaceutical stability testing
• Electronic reliability testing
• Vehicle component testing
• Plant growth chambers
• Aerospace / altitude testing
• Engine testing
• Testing of military equipment
• Packaging sample testing

Exemplary test specifications

Test type	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 properties of our climate chambers

PID control

Our high-quality temperature and climate chambers are equipped with PID control. PID stands for proportional, integral and differential. This control system is more efficient than a simple on-off control system, as it approaches predefined variables such as temperature or humidity quickly and without undesirable overshooting and precisely maintains the predefined values.

The intelligent PID control in the Kambic environmental test chambers ensures an extremely uniform and stable temperature distribution across the entire test chamber and temperature range.

Peltier temperature control systems for maximum temperature stability

Equipped with a Peltier temperature control system, fast heating and cooling times with high precision are guaranteed. The ultra-stable temperature control and uniformity of our Peltier climatic test chambers of up to ±0.03 °C is unrivaled on the market.

The stability chambers are designed for climate (environmental simulation), material and stability tests. The Peltier system makes them quiet, space-saving, environmentally friendly and economical at the same time. The innovative Peltier technology in Kambic's climatic test chambers enables stable and precise long-term tests. The temperature control from +8 ºC to +55 ºC and the active humidification and dehumidification from 10 % to 98 %rh are optimally matched to the requirements of stability analysis.

The environmental test chamber with its heating and cooling concept based on Peltier elements is also highly economical. Energy savings of up to 90 % can be achieved over the course of a test run lasting several months. Due to its quiet operation, the constant climate chamber is not only ideal for environmental simulation and long-term material tests, but also for breeding insects and reptiles.
