Stop trading efficiency for control. This heated recessed air door delivers continuous, directed airflow and reliable heat output to maintain environmental separation in high-traffic openings while reducing infiltration and energy loss. Designed for commercial installations, the unit combines robust motors and safety certifications to support facility managers, restaurateurs, and institutional buyers.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe exterior surfaces daily with a microfiber cloth and a mild detergent solution (1 tablespoon detergent per gallon of warm water) and rinse with clean water. Sanitize high-touch zones—mounting brackets, access panel handle, and control switches—using an EPA-registered sanitizer per label. Vacuum intake grilles weekly and inspect motors and fasteners monthly, tightening as needed. Regular cleaning prevents contamination transfer, maintains appearance, and supports health code compliance.#@@#Additional Info#@#The Berner ARD12-2120E heated air door offers 120" coverage with two 1/2 HP motors, ten-speed airflow, and 28 kW electric heat at 208 volts, 3-Ph for mounting up to 12 ft; cULus certified, made in USA, it aids air management and energy control.#@@#General Info#@#Description #@#
Stop trading efficiency for control. This heated recessed air door delivers continuous, directed airflow and reliable heat output to maintain environmental separation in high-traffic openings while reducing infiltration and energy loss. Designed for commercial installations, the unit combines robust motors and safety certifications to support facility managers, restaurateurs, and institutional buyers.
Two 1/2 HP motors provide redundancy and sustained performance for openings up to 12 feet. Each motor operates on 208 volts, 3-Ph power and connects to the ten-speed controller to match airflow to site demand.
A ten-speed selector enables precise airflow tuning to balance comfort and pressure differentials at entryways. Adjustments reduce load when traffic is light and increase output during peak periods to protect conditioned spaces.
The electric heater delivers 28 kW to maintain temperature separation across the threshold. Engineers can expect consistent thermal performance for interior environments subject to frequent door cycles.
The unit installs recessed into the header and features a hinged white aluminum bottom access panel for servicing controls and elements. The enclosure accommodates mounting heights up to 12 feet and spans 120 inches of clear width.
The assembly meets cULus certification and ships from a U.S. facility, providing documented safety compliance for commercial installations. Facilities with strict procurement standards receive traceable specification data for approval workflows.
Rated for 60 hertz operation, the air door suits standard North American electrical infrastructure and interfaces with three-phase distribution. The unit weighs approximately 376 pounds and pairs with existing control circuits for coordinated door management.
