Original Press Release:



In-Ground Door Operator by brookfield Industries, Inc.



brookfield industries inc, is pleased to announce the addition of the NB-500-LE-OPCON In-Floor Door Operator to our product line.  Equipped with all the standard features of our heavy duty NB-500- LE Low Energy Swinging Door Operator, we now offer a UL50 TYPE 4, In-Floor Underground Conversion by OPCON USA that is also UL 325 Listed.



Designed specifically for heavy-duty applications, this power open/power close operator (no springs) is rated for doors weighing up to 2500 lbs or an operating torque of 1000 lb-in; thus, providing enough flexibility for heavier doors to resist stack pressure or wind loads, yet still be compliant with ANSI 156.19 when required.  For more information, please see:  http://catalog.brookfieldindustries.com/product/ators-series-nb-500-low-energy-operators-1/nb-500-le-opcon-in-floor-door-operator



Stack Pressure Monitoring (SPM) is now optional on all low energy models.  When an input signal is received from an external monitoring device (not included), the operator will increase the torque to the motor in order to resist a pressure differential acting on the door.  Once this “event” is over, the operator will return to “normal” or low energy operation.  Safety sensors can be integrated during the “event” mode when required.



brookfield industries inc, is an OEM manufacturer of Precision Engineered High Capacity Hinges and Industrial Door Operating Systems for specialty doors used in the following industries: radiation therapy, industrial radiation, petrochemical, security, acoustical, EMI/RF, nuclear, and heavy commercial/architectural.
