Charles Ross & Son Company offers a line of explosion-proof control panels for mixers. The control panels' operator stations includes a digital readout for speed and cycle time. The control panels are designed to be mounted close to the mixer in a hazardous area, and wired to a variable frequency drive that is installed outside the mixing room, according to Ross. Type X or Z purge control panels are also available for users who require mixer portability with no remote wiring.
