Since 1998, ASC Tornado has made industrial mixers and agitators in the USA, pairing custom design and fabrication with its patented blade technology. Based in Abbottstown, Pennsylvania, the company assembles every mixer at its own tool-and-die, machine-building and fabrication facility, tailoring equipment for applications from small-batch pails to demanding industrial processing. Its Tornado blades are designed to draw material through the blade and can reduce mixing time by 50–80% compared with conventional propeller blades.
