ConProTec Inc. (Salem, N.H., U.S.A.) now offers aluminum Motionless Mixer Shrouds, designed to provide extra support and protection to the housings of static mixers used on any type of meter mix machinery. Recommended for high-pressure dispensing applications, the shrouds prevent mixer expansion or rupture under extreme pressures and eliminate the possibility that catalyst or resin could flow down the inner surface of a bulging housing sidewall, bypassing the mixer.
