Its quad&#8209;core processor manages all of the advanced software features and user interface, but is technically separated from the dedicated, high&#8209;speed MixModule control unit which manages all of the instrumentation\/flow&#8209;control hardware. This two&#8209;pronged design allows for real&#8209;time capabilities that would not otherwise be possible with a software&#8209;only solution.[\/et_pb_accordion_item][et_pb_accordion_item title=&#8221;Can MXM be upgraded or reconfigured after purchasing?&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; open=&#8221;off&#8221;]Yes &#8211; The MXM standard chassis can handle up to 6 independent gas channels, so if the system is originally ordered with only two channels, up to four more can be added at a later date by returning the system to Alicat<sup>&reg;<\/sup> Scientific for retrofitting.

However, our sister company <a href=\"https:\/\/www.permapure.com\/\" target=\"_blank\" rel=\"noopener\">Perma Pure<\/a> may be able to assist in providing a solution to humidify the dry blended gas stream created by the FusionFlow MXM instrument.<\/p>[\/et_pb_accordion_item][et_pb_accordion_item title=&#8221;Does MXM allow for mixing fuel gases with oxidizing gases?&#8221; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; open=&#8221;off&#8221;]Technically, it is possible to make perfect, stoichiometric mixtures with the MXM. However, the FusionFlow team <strong>does not\u00a0condone<\/strong> the use of any of its product offerings for the purpose of creating explosive or flammable gas blends. Please contact us to discuss the details and available alternatives if these mixtures are required in your process. Alternatively, for explosive environments, see <a href=\"https:\/\/www.alicat.com\/products\/class-i-div-1\/\">Alicat\u2019s Intrinsically Safe gas flow and pressure instrumentation<\/a>.[\/et_pb_accordion_item][et_pb_accordion_item title=&#8221;Can the same gas type be connected to more than one MFC control channel?&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; open=&#8221;off&#8221;]<p>Yes! If higher flow rates are required of the same gas within the mixture, the same gas source can be connected to as many available channels as needed to increase capacity of that gas. Further, these channels can be sized differently, allowing for a \u2018high dynamic range\u2019 of flow for that gas.<\/p>\n<p>For example, argon is assigned to a 5 SLPM unit as well as a 50 SLPM unit, allowing for a total possible argon flow of 55 SLPM. Depending on the instantaneous requirement for argon in the mixture, MXM will choose to utilize either (or both) controllers to meet the demand, with the best accuracy and control possible.<\/p>[\/et_pb_accordion_item][et_pb_accordion_item title=&#8221;Can MXM change gas mixtures \u201con the fly\u201d?&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; open=&#8221;off&#8221;]<p>Yes &#8211; not only can unlimited gas recipe presets be created and selected at will (while flowing), but the automation functionality also allows linear interpolation between presets at the user\u2019s chosen time interval.
