Motor Operation

Motor operation is the most effective and consistent method of opening larger, higher cycle doors and offers the following benefits:

  • Door Longevity: Offers the most consistent method of operation, and as such, maximizes door longevity
  • Ease of Use: Can link to one-touch, or even no touch, opening triggers such as a push button station or a loop detector
  • Safety: Accommodates entrapment devices such as photo eyes and sensing edges
  • Remote Activation: Can be integrated into master building controls to operate doors remotely
  • Durable: Can be designed to withstand weather, chemicals, or even explosions

 

Motor operation does require power to the opening and enough clearance to mount the motor. In the event of a power outage, auxiliary operators can be used (push up or chain, depending on door size and configuration). You often see motor operators in parking garages, distribution facilities, paint booths, and car washes.

Concealed Tubular Motors

A concealed tubular motor offers a smaller, more compact motor design for counter shutters, fire shutters, grilles and gates. It is the ideal solution for strict dimensional limitations around the header, as it requires less clearance than standard motor operators. In addition, due to its reduced size, it is ideal for enhancing aesthetics.

Benefits of Tube Motor Operators:

  • Convenience of motor operation in a low profile, concealed design
  • Promotes ergonomic operation of counter door units without sacrificing aesthetics
  • Quiet and smooth motor operation
  • Motor drive chain is not required
  • Auxiliary crank operation standard

 

Recommended Applications:

  • Counter Doors or Grilles that require convenient motor operation in limited headroom conditions
  • Aesthetic motor operation that eliminates the need for a bulky motor cover
  • Low cycle applications, rated for 10 cycles per day, 4 per hour
  • Operation for greater than 10 minutes/10 cycles on a maximum size unit may engage thermal overload, after which the operator must be allowed to cool for approximately 15 minutes to return to service

 

Product Application Requirements:

  • The tube motor requires 115 VAC power
  • Counter Shutter – Maximum width of 21’ 4” - Maximum height of 10’ 4” - Maximum of 180 Square Feet
  • Counter Shutters with Integral Frame and Sill – 11’ 7” wide by 4’ 10” high
  • VisionAire Grilles/SentryGate Grilles - Size limits based on operator rating and curtain configuration
