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 man- power. 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.

OPERATOR MOUNTINGS (INTERIOR)+


VF mounting (vertical front-of-coil) is standard for Service doors and steel grilles up to approx. 270 sq. ft., and for all aluminum Grilles. VW mounting (vertical wall) is standard for larger steel doors and grilles, and for all Fire doors.


Optional mountings (HT, HS, HF) are available when in accord with good engineering practice.


+For doors mounted on exterior face of wall, with operators on exterior (i.e., types SEM & AEM), the VW mounting is applied
