This recessed heated air door mounts into architectural openings and maintains conditioned zones while permitting high throughput. Engineers designed the assembly for commercial installations that require consistent air separation, robust power handling, and serviceable access.
LongDescription#@#NA#@@#Cleaning Instructions#@#Clean air doors reduce contamination risk on high-touch zones such as chair backs and door handles. Use a mild detergent and water to wipe aluminum surfaces and access panels; avoid abrasive pads. Disconnect power before servicing, then remove dust with a soft brush from motor housings and vents. Sanitize with an EPA-registered surface disinfectant where required. Inspect mounts and fasteners monthly and tighten as needed to maintain performance and compliance.#@@#Additional Info#@#The Berner ARD12-3108E recessed heated air door is 108" long, has electric heat, three 1/2 HP motors with ten speeds, and 42 kW output for heights up to 12 Ft.; operates at 208v, 3-Ph, cULus certified, made in USA, for foodservice and facility use.#@@#General Info#@#Description #@#
This recessed heated air door mounts into architectural openings and maintains conditioned zones while permitting high throughput. Engineers designed the assembly for commercial installations that require consistent air separation, robust power handling, and serviceable access.
Three independent motors deliver targeted airflow across the full plenum, each motor rated at 1/2 HP to balance torque and reliability. Ten selectable speeds let operators tune output for variable door heights and traffic conditions while reducing unnecessary energy use.
The unit provides electric heat at 208 volts and 3-Phase power to sustain temperature control in cold entries. Integrated heating ensures consistent thermal barrier performance for mounting heights up to 12 feet.
A ten-speed control scheme offers precise airflow modulation for variable applications such as retail, healthcare, and institutional kitchens. Programmable speed selection enables staff to prioritize comfort, efficiency, or throughput without complex rewiring.
A hinged aluminum bottom access panel allows front service and inspection without removing the assembly from its recess. Technicians perform motor, heater, and control maintenance quickly, minimizing downtime in high-usage environments.
The air door carries cULus recognition and ships assembled in the USA, meeting common safety and code expectations for commercial facilities. Construction uses corrosion-resistant materials suited to repeated use in hospitality, education, and healthcare settings.
Designed for openings approximately wide and rated for maximum opening height, the unit fits large storefronts and institutional entries. The installed weight requires reinforced mounting but provides a stable, vibration-resistant installation.
