Environmental Chambers – KB Series

Darwin Chambers KB series Environmental Chambers are a top selling unit. It is quiet, easy to clean, highly reliable and ideal for laboratory use. Our environmental chamber offers hot gas bypass control of refrigeration and resistive heat to facilitate reliable, critical temperature and humidity control.

All KB series environmental testing chamber models are designed to have a temperature range of 2 to 50Celsius. Temperatures greater than 50o Celsius or lower than 2o Celsius can be achieved with optional upgrades to construction and components.

All KB series environmental chambers come standard with Fuji's PXF4 microprocessor, but we can offer others if preferred. Unlike many proprietary controllers on the market, these controllers are available off the shelf and have been proven in tens of thousands of installations. All necessary functions are included in our Features section below. Many additional options are available both regarding control and recording of data (chart recorders and loggers)

KB Series Features

KB Series

The KB series chambers feature hot gas by-pass technology which controls the temperature of the epoxy coated evaporator for greater uniformity. Compressors in our KB series of environmental chambers come with a three year warranty - which is one of the longest in the industry. All of these models run with 0.25 - 0.67hp compressors making them efficient enough to run on 15 amp, 110 volt circuits.

Widely Proven, Non-Proprietary Controllers

Standard controllers for the KB Series are manufactured by Fuji Electric and are ideal for environmental testing chambers. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, ramp/soak, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen Bradley etc.)

Services and Warranties

We offer technical support throughout the lifetime of your chamber. In addition to standard warranties, we also offer extended warranties for cooling components, parts and labor. We also provide qualifications, validations and preventive maintenance services at an additional cost. Please ask for a quote.

Superior Control and Uniformity

The ultrasonic humidification system provides excellent humidity control and avoids hot spots seen during chamber mapping of steam boiler equipped chambers. Standard control at the sensor in these chambers is ±0.2°C and ±0.3%RH.

Greatly Reduced Direct and Indirect Energy Loads

The KB Series chambers utilize less energy than comparable stability chambers and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers. Electrical energy savings by the KB series vs. steam boiler equipped chambers can easily amount to hundreds or thousands of dollars saved per year.

Quiet Operation

The KB chambers utilize quiet and highly efficient DC fans. Locating these chambers in laboratory workspaces is a viable option.

Frequently Asked Questions (FAQs) About Environmental Chambers

What are Environmental Chambers Used For?

Environmental chambers have a variety of applications in pharmaceuticals, industrial manufacturing, materials, electronics, and other industries. Also known as climatic chambers, environmental chambers allow you to reproduce certain tests for quality control purposes.

This includes testing for:

  • Humidity
  • Heat
  • Cold
  • Light
  • Pressure
  • Corrosion/Weathering

Environmental chambers allow you to accelerate the aging products of materials--this is important for determining a product's longevity and shelf life. You'll have superior control over every variable to ensure accurate results.

What Are the Types of Environmental Chambers?

Environmental chambers are designed to regulate temperature, humidity, pressure, and other environmental factors to mimic specific conditions encountered in nature or industrial settings. With a wide range of chamber types available, researchers and engineers can create custom environments tailored to their unique testing requirements, enabling them to study the effects of environmental variables on materials, products, and organisms.

  • Temperature Chambers: These chambers control temperature levels to simulate various environmental conditions, from extreme cold to high heat.
  • Stability Chambers: These chambers are engineered to meet FDA/ICH requirements and employ ultrasonic humidification that is easily controlled.
  • Humidity Chambers: Humidity chambers regulate humidity levels, allowing researchers to create specific moisture conditions for testing and experimentation.
  • Combined Environmental Reach-In Chambers: Some chambers combine multiple environmental factors, such as temperature, humidity, and vibration, to create highly complex and realistic testing conditions.
  • Climatic Chambers: Climatic chambers combine temperature and humidity control to replicate complex environmental conditions, such as those found in tropical or arid climates.
  • Altitude Chambers: Altitude chambers simulate high-altitude environments by reducing air pressure, allowing researchers to study the effects of low atmospheric pressure on various materials and components.
  • Salt Spray Chambers: Salt spray chambers create corrosive environments by spraying saline solutions onto test specimens, allowing researchers to assess the corrosion resistance of materials and coatings.

Custom-configured precision environment chambers are tailored to accommodate diverse applications such as seed storage, cannabis cultivation, and insect rearing. These chambers exceed stringent requirements, offering a humidity range from ambient to 90% at a 40°C dew point, with humidity control accuracy of ± 0.3%.

Who Would Use an Environmental Chamber?

Environmental chambers find applications across diverse industries and research fields due to their ability to simulate and control specific environmental conditions. Here are a few use-cases and institutions that might need an environmental chamber:

  • Research Institutions: Academic and scientific organizations use environmental chambers for conducting experiments and studies.
  • Pharmaceutical Companies: Pharmaceutical companies utilize environmental chambers for testing drug formulations, stability studies, and packaging evaluations.
  • Automotive Industry: Manufacturers rely on environmental chambers for testing the performance and durability of vehicle components under various conditions.
  • Electronics Manufacturers: Companies in the electronics industry use environmental chambers to test part reliability and functionality.
  • Aerospace and Defense: Aerospace and defense organizations employ environmental chambers for testing materials, equipment, and components used in aircraft, spacecraft, and defense systems under extreme conditions.
