CDX® Commercial Door Operator: Key Features

The CDX® Commercial Door Operator is designed for light-duty commercial applications, offering a blend of durability and reliable performance. It features a robust 1/2 horsepower motor with high start torque and an intermittent-duty rating, ensuring it can handle frequent use in demanding environments. The operator is UL 325 listed, meeting safety standards for commercial door operation.

Key components include a NEMA 42 frame open drip-proof motor construction for protection against environmental factors, and an instant reversing mechanism with automatic reset thermal overload for enhanced safety and longevity. The drive reduction system utilizes a helical gear primary reduction and a hardened bevel gear secondary reduction, contributing to its smooth and efficient operation.

CDX® Operator Performance and Durability

Engineered for consistent operation, the CDX® Commercial Door Operator is tested and approved by UL for up to 5 cycles per hour at a rated load of 70 ft-lbs/sec. This ensures it can withstand the demands of commercial settings without compromising performance. The power train incorporates oil-impregnated bushings, a design choice aimed at maximizing the operator's lifespan and minimizing maintenance requirements.

Durability is further enhanced by a sophisticated limit system that remains synchronized with the door's movement, even during release operations. A cycle counter logs total cycles, providing valuable data for warranty claims and service scheduling, ensuring proactive maintenance and extended operational life for the unit.
