The Ross Interfacial Surface Generator (ISG) is a patented static mixer designed for laminar flow processes such as blending a minor component into a viscous stream. Each ISG element consists of four passageways set at oblique angles. Material near the periphery on the inlet side of the element emerges near the center on the outlet side. This radial mixing eliminates the wall smearing effect encountered in other static mixer devices, according to the company. The mixer can be supplied as a complete plug-in module or as individual elements for installation into an existing pipe or tubing; elements are available in a range of sizes from 5/8” to 24" diameter.
