A reliable source for Environmental Chambers information and leading Environmental Chambers Companies & Manufacturers.

An environmental chamber or climatic chamber is an enclosed area that is used to test the effects of particular environmental conditions on industrial products, machine components, electronics, and biological items. These climatic chambers are designed to artificially control certain conditions such as heat and humidity. Any environmental condition can be created artificially, such as an extremely hot, cold, or even corrosive environment. Read More…

Environmental Chambers Environmental chambers reproduce environmental conditions within a contained space for the purposes of evaluating the long-term effects of specific changes upon objects such as industrial products, electronic products, and other components.

An environmental chamber or climatic chamber is an enclosed area that is used to test the effects of particular environmental conditions on industrial products, machine components, electronics, and biological items. These climatic chambers are designed to artificially control certain conditions such as heat and humidity. Any environmental condition can be created artificially, such as an extremely hot, cold, or even corrosive environment. The conditions may include:

  • Extreme temperatures
  • Thermal shock
  • Altitude
  • Moisture or relative humidity
  • Corrosion testing
  • Salt spray
  • Rain
  • Weathering
  • Vacuum

The manufactured specimen is introduced into the chamber, and different conditions are applied according to requirements. The sizes of test chambers can vary from 1 cubic foot (30cm) to 12,000 cubic feet (3,600 m).

Environmental Chambers

Working Principle of Climatic Chambers

  • All conditions of the chambers are controlled manually through a wide range of mechanical processes.
  • The temperature is controlled by electric resistors either cooling or heating up the refrigeration unit.
  • Water vapors are introduced into the chambers by steam generators.
  • The humidity level is adjusted by one of two methods, ultrasound technology or water evaporation with a heat source.
  • Corrosive conditions are simulated by emitting salt spray on the product.
  • Not every test chamber can simulate each and every type of condition.
  • For testing a product in a specific condition, specified test chambers are engineered.

Types of Environmental Chambers

  • Temperature Chambers

    • The temperature test is the most important test for a product. It may continue for days or weeks with the same gradient.
    • These tests are called thermostatic tests and are used to determine the resilience of a product against temperature extremes.
    • The temperature can vary from -94°F (-70oC) to 356°F (180oC).
  • Humidity Chambers

    • The humidity test is the second most important test of a product.
    • Humidity and temperature test chambers are linked with each other, as heat is required to produce humid conditions.
    • The testing of a product can be done either in a static state without changing the conditions or in a dynamic or moving state.
      Humidity Chambers
  • Vibration Chambers

    • Vibration testing is done by using mechanical and electrodynamic shaking.
    • The shaking can be horizontal, vertical, or along three different axes.
    • A product is tested under a highly accelerated life test and highly accelerated screen test to check its liability.
  • Stability Chambers

    • Stability chambers are used to test the shelf-life of the product for shipping and storage.
    • It is done by creating controlled conditions of temperature and humidity over an extended period of time.
  • Corrosion Test Chambers

    • These test chambers are used to determine the ability of a product to withstand a corrosive environment.
    • A salt spray is applied to the product surface with the help of a nozzle in the chamber.
    • This test chamber determines the quality of the coatings and finishings of the product.
      Corrosion Test Chambers
  • Thermal Shock Chambers

    • Thermal shock chambers are used to check the ability of the product to withstand sudden changes in environmental conditions, such as temperature and humidity.
    • The specimen is put under rapid and successive changes of temperature of 86°F (30oC) every minute or more.
  • Vacuum Chambers

    • Vacuum chambers are used to test the products that are used in the aerospace and defense industries.
    • This test is performed by creating an extremely low air pressure and removing all other gasses from the enclosed chamber.
    • These tests are performed to check the working of the product in a vacuum.
  • Altitude Chambers

    • Altitude chambers are used to test the product’s resilience under low pressure at high altitudes.
    • These chambers can simulate an altitude of up to 98,000 ft (30,000 m).
    • Decompression and explosive testing are also a part of this testing chamber.
      Altitude Chambers
  • Anechoic Chambers

    • Anechoic testing is done to check how much noise a product is producing.
    • This testing chamber is the size of a room with walls covered in materials to block any incoming sound.
    • The anechoic chambers work with the elimination of echos and all other sounds.

Industries Using Environmental Chambers

  • Automotive Industries

    Small environmental chambers are used to check the reliability of the automotive parts before assembly.

  • Electronics Industries

    Electronics parts such as circuits, boards, and switches are checked in these chambers before launching in the market. This is because they can be damaged by many environmental factors such as humidity, temperature or corrosive environments.

  • Pharmaceutical Industries

    Pharmaceutical industries use these chambers to verify the lifespan and shelf-life of medicine.

  • Medical Facilities

    Medical devices are monitored under these chambers before use.

  • Defense Industry

    Military equipment is tested in these chambers to check if it can withstand harsh environments.

  • Telecommunications Industries

    Telecommunication industries use these chambers to check their products in regard to altitudes.

  • Solar Power Plants

    Solar panels are tested in environmental chambers to check if they can withstand a fluctuating environment or not.

  • Aerospace Industry

    The aerospace industry uses vacuum test chambers to check the working of their products in space.

Types of Environmental Chambers

There are three types of environmental chambers according to their size. These are:

  • Bench-Top Chambers

    Bench-top chambers are usually 0.5 cubic feet (15 cm) to 5.5 cubic feet (1.68 m). These are the smallest in size, and are used for commercial and industrial tests where a low temperature is required.

  • Reach-In Chambers

    These are of size between 4 and 70 cubic feet (1.2 and 21.3 m). These can test for temperature, altitude, humidity, rain, solar and vibration.

  • Walk-In Chambers

    These chambers are big enough to walk or even drive into. These are used to test large components, from computers to satellites.
