Stop sacrificing control for coverage. This heated recessed air door provides consistent thermal separation and continuous airflow for extended openings while supporting heavy-duty service environments with a robust electrical and mechanical design.
LongDescription#@#NA#@@#Cleaning Instructions#@#Use a soft cloth and mild detergent to wipe aluminum housing, louvers, and access panel. Remove heavy dust with vacuum before wiping. Clean high-touch controls and bottom edge with EPA-approved disinfectant, following contact time on label. Inspect motors and mounts for debris; clear buildup under shelves or near openings to deter pests. Regular cleaning prevents cross-contamination, supports health-code compliance, and preserves finish and function.#@@#Additional Info#@#Berner ARD12-3144E recessed heated air door delivers a 144" architectural unit with three 1/2 HP motors, ten-speed airflow control, 42 kW electric heat, and 208v 3-Ph operation; cULus certified and made in USA for mounting heights up to 12 feet.#@@#General Info#@#Description #@#
Stop sacrificing control for coverage. This heated recessed air door provides consistent thermal separation and continuous airflow for extended openings while supporting heavy-duty service environments with a robust electrical and mechanical design.
#@@# Recessed Installation#@#
Installers benefit from a flush-mounted solution that conceals the unit within the opening, ensuring clean sightlines and protected operation. The recessed configuration accommodates mounting heights of up to 12 feet and spans a nominal length of 144 inches, allowing for seamless integration into long entrances without protruding housings.
#@@# Electric Heating Package#@#
Choose an electric heat source rated at 42 kW to maintain temperature differentials across large openings and minimize infiltration losses. The 208 volts, 3-phase supply ensures stable power delivery for the heating elements while reducing voltage drop over commercial runs.
#@@# Multi-Motor Drive#@#
Three 1/2 HP motors provide distributed airflow across the entire length, preventing dead zones and enhancing occupant comfort near doors. Each motor features ten speed settings, enabling technicians to balance thrust with noise levels and energy consumption effectively.
#@@# Ten Speed Control#@#
Operators gain precise airflow modulation with ten discrete speeds tailored to seasonal demands and traffic patterns. Adjustments lead to immediate changes in thrust, which helps maintain internal conditions while minimizing energy waste.
#@@# Durable Service Access#@#
A hinged white aluminum bottom access panel allows tool-free entry for routine maintenance and motor servicing without removing the assembly from the opening. The corrosion-resistant panel withstands wear in high-traffic or humid environments, simplifying filter and motor inspections.
#@@# Compliance and Origin#@#
The unit holds cULus certification and is shipped with components manufactured in the USA, supporting code compliance and domestic sourcing preferences.
