  • Delivering mission critical for NASA – Case Study

    Delivering mission critical for NASA – Case Study

    Early developments in the evolution of mass flow meters in the 1950’s were largely driven by the need for highly accurate readings. Over the last 50 years the demand for substantially reduced margins of error has only intensified. For the ...

  • Gas mixing and blending equipment – Case Study

    Gas mixing and blending equipment – Case Study

    How They Work A specific gas blend within a chamber must be produced by a procedure known as ideal gas mixing (or gas blending). In this example, synthetic air composition is maintained at a mix ratio of 78% N2, 21% O2 and 1% Ar. A miniature ...

  • Fiberglass manufacturing requires precise gas ratio control – Case Study

    Fiberglass manufacturing requires precise gas ratio control – Case Study

    Fiberglass insulation manufacturing is almost akin to making cotton candy!  A mixture of silica and other components are melted and passed through a spinning extruder, then rapidly cooled with compressed air. As older fiberglass ...

  • High voltage switchgear SF6 maintenance – Case Study

    High voltage switchgear SF6 maintenance – Case Study

    Just like the main circuit breaker in your home, city grids have main on/off switches called switchgears. When these high voltage switchgears open or close, huge "lightning-like" arcs of electricity are created. If not maintained correctly, these ...
