  2. Thermal vacuum chamber - Wikipedia

    en.wikipedia.org/wiki/Thermal_vacuum_chamber

    A thermal vacuum test chamber, with its door open, at NASA's Johnson Space Center. A thermal vacuum chamber ( TVAC ) is a vacuum chamber in which the radiative thermal environment is controlled. Typically the thermal environment is achieved by passing liquids or fluids through thermal shrouds for cold temperatures or through the application of ...

    en.wikipedia.org/wiki/Materials_for_use_in_vacuum

    Materials for use in vacuum are materials that show very low rates of outgassing in vacuum and, where applicable, are tolerant to bake-out temperatures. The requirements grow increasingly stringent with the desired degree of vacuum to be achieved in the vacuum chamber. The materials can produce gas by several mechanisms.

    The aluminum test chamber is a vacuum-tight aluminum plate vessel that is 100 feet (30 m) in diameter and 122 feet (37 m) high. Designed for an external pressure of 2.5 psi (17 kPa) and internal pressure of 5 psi (34 kPa), the chamber is constructed of Type 5083 aluminum which is a clad on the interior surface with a 1 ⁄ 8 in (3.2 mm) thick type 3003 aluminum for corrosion resistance.

    en.wikipedia.org/wiki/Aseptic_processing

    Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...

  6. Vacuum chamber - Wikipedia

    en.wikipedia.org/wiki/Vacuum_chamber

    A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low- pressure environment within the chamber, commonly referred to as a vacuum . A vacuum environment allows researchers to conduct physical experiments or to test mechanical devices which must operate in outer space (for example ...
