Motor Operators - CGEXTERNAL

MOTOR OPERATORS
Motor operators offer the most efficient means of operation. They soon pay for themselves by conserving heat, by more efficient traffic flow, by savings in manpower. Further, for frequent or rapid use, remote controlled motor operators are mandatory. Motor operators are integral power units engineered for long life and reliability. For each door or grille requirement, horsepower and gear reduction are designed conservatively.
