All Constant Climate Chambers at a Glance

What is a Constant Climate Chamber?

Constant climate chambers are specially designed climate test chambers that maintain stable temperature and humidity conditions over extended periods. These constant conditions are essential for standards-compliant stability testing, durability testing, and ageing processes.

Unlike dynamic testing methods, the climate inside the chamber remains constant – ideal for standardised tests and reliable comparability of results. For dynamic testing, we recommend our Climate Test Chambers.

Constant Climate Chambers – Key Benefits

Constant climate chambers offer maximum precision, reliability, and efficiency in daily operation. They have been specifically designed for demanding stability and long-term testing and ensure consistently reproducible conditions – even under high workloads.

Precise control of temperature and humidity, combined with particularly uniform climate distribution throughout the chamber, ensures reliable test results – even when fully loaded. At the same time, modern technologies such as energy-efficient Peltier technology enable sustainable and economical operation.

In everyday laboratory use, constant climate chambers also stand out thanks to their quiet, low-vibration operation and intuitive controls, allowing easy programming and operation. Comprehensive documentation and monitoring functions further enhance their capabilities and are particularly important in regulated industries such as the pharmaceutical sector.

The key benefits at a glance:

  • Maximum temperature and humidity stability

  • Uniform climate distribution – even when fully loaded

  • Energy-efficient technologies (e.g. Peltier technology)

  • Quiet, low-vibration operation

  • Intuitive controls and easy programming

  • Comprehensive documentation and monitoring functions

  • Compliance with international standards such as ICH Q1A

This makes constant climate chambers the ideal choice for precise, standards-compliant, and reliable long-term climate testing.

Precise Temperature and Humidity Control

Optimum Temperature Conditions

Constant climate chambers offer a precisely controllable temperature range, which is essential for simulating real-life storage and environmental conditions. This allows chemical and physical processes to be analysed reliably.

Precise Humidity Control

In addition to temperature, humidity plays a key role. Precise control of relative humidity enables realistic testing conditions – particularly for hygroscopic materials or sensitive products.

Interaction of Temperature and Humidity

Only the combination of both factors enables meaningful stability testing. Constant climate chambers provide precise coordination of temperature and humidity for reliable and reproducible results.

Peltier Technology – Efficient and Sustainable

The Peltier technology used in the KBF-S ECO series offers significant advantages:

  • Energy-efficient operation

  • No conventional refrigerants required

  • Particularly quiet and low-vibration operation

  • Precise temperature control

This technology makes the units not only economical to operate but also particularly environmentally friendly.

Documentation and Quality Assurance

Complete documentation is essential for standards-compliant stability testing.

Constant climate chambers offer:

  • Automatic recording of temperature and humidity data

  • Support for compliance with ICH Q1A guidelines

  • Interfaces for data export and monitoring

  • Validatable processes for regulated industries
