Stop trading comfort for control. This heated architectural air door integrates electric heating, multi-motor airflow, and precise speed selection to maintain temperature separation and reduce infiltration in high-traffic openings. Built for continuous duty in commercial settings, this unit supports mounting heights up to 12 feet while delivering consistent performance across long spans.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces and high-touch zones (menu rails, handles, chair backs, shaker tops) with EPA-registered disinfectant following label dwell time. Use mild detergent and warm water for routine cleaning; rinse and dry. Inspect crevices and under booths weekly; remove crumbs and residue to deter pests. Clean prevents cross-contamination, supports health-code compliance, preserves finishes, and maintains customer confidence.#@@#Additional Info#@#Berner ARD12-3120E heated air door offers 120" coverage with three 1/2 HP motors, ten-speed airflow, and 42 kW electric heat at 208 volts, 3-Ph. cULus certified, made in USA, it mounts to openings up to 12 ft for commercial traffic control.#@@#General Info#@#Description #@#

#@@# Three Motor Design#@#
Three 1/2 HP motors deliver staged airflow for robust curtain velocity across wide openings. Engineers configure each motor independently to match pressure and traffic patterns, enabling reliable separation without overworking individual drives.
#@@# Ten Speed Control#@#
Ten discrete speed settings provide granular control over discharge velocity and energy use. Operators adjust airflow precisely to balance thermal retention and draft management, optimizing runtime for varying occupancy and exterior conditions.
#@@# Electric Heat Package#@#
A 42kW electric heat assembly supplies rapid thermal gain when ambient conditions demand. Facility managers deploy the heat circuit to minimize cold air penetration during frequent door cycles, reducing load on building HVAC systems.
#@@# Extended Length Format#@#
At 120 inches nominal length with fit tolerances to 131 inches, the unit spans large openings without splicing. Installers place this recessed section above continuous doorways to achieve uniform coverage and avoid dead zones that allow conditioned air loss.
#@@# Recessed Installation#@#
The recessed configuration integrates into soffits and overhangs to preserve architectural sightlines while maintaining performance. Architects retain a minimal visual profile, and facility staff access the hinged aluminum bottom panel for service without ceiling removal.
#@@# Certifications And Origin#@#
cULus certification verifies compliance with North American safety and performance standards, and domestic manufacture supports expedited parts availability.
#@@#Delivery Details#@#
• Please ensure to handle the product with utmost care.
• Check if the product you have received has all the essential parts and accessories.
• Make sure to examine the product for damage before signing the delivery receipt.
• Contact customer service for delivery concerns.
• Delivery times may vary based on location.#@@#deliverynotes#@#NA#@@#Maintenance Guide#@#Inspect the ARD12-3120E air curtain weekly for dust on intake grilles and motor housings. Remove deposits with low-pressure compressed air. Lubricate motor bearings per manufacturer intervals with specified grease. Verify electrical connections and torque to panel specs while power is off. Clean the heated element area with a soft brush and vacuum; avoid moisture. Test airflow and adjust ten-speed controls to match mounting height and door width, and record service actions.
