mbw SF6 room process factory

SF6 electrical circuit breaker is a device where a current is operating with SF6 or Sulphur Hexafluoride being carried on its contacts. It breaks off the power when there's an excessive electricity supply that exceeds the allowed voltage to prevent circuit overload.

  • Multiple-Breath Washout as a Lung Function Test in Cystic

    The two most commonly reported parameters from MBW tests are the lung clearance index (LCI) and moment ratios (MRs). Measurements of LCI and MR are taken during the washout period. During the washout phase, subjects inhale gases that do not contain the test gas of interest (i.e., room air for SF6 and 100% oxygen for N2).

  • Multiple Breath Nitrogen Washout: A Feasible Alternative to

    Feb 15, 2013 · Therefore, the current customized system is neither suitable for multi-center clinical research nor clinical practice. Multiple breath nitrogen washout (MBW N2) offers a possible alternative to mass spectrometry based SF 6 washout (MBW SF6). N 2 is a resident gas and permeates even poorly ventilated lung units, which may not be the case during MBW SF6. Thus, the physiological attributes of the respective tracer gases may lead to differences in measurements obtained with the two systems.

    As a hybrid of the high-pressure and refrigeration process, heat-exchanged systems rely on a series of forced-air coolers to extract heat from the compressed SF 6. As a benefit of reduced temperatures and pressures, this approach allows gas to be liquefied at a slightly faster rate than the direct high-pressure approach.
