The second generation of the In-Ceiling Mount air curtain features the Intelliswitch 2™ digital controller and the new patent-pending Pro-V nozzle. The Intelliswitch 2 features a thermostat, three-speed fan control, time clock, and timer delay. The user-friendly format offers choices of three defaults or full-programming operation. The built-in controller negates the need for installing separate wall-mounted mechanical switches and thermostats, and reduces control installation costs by operating from a hand-held wireless remote control. The Pro-V Nozzle design produces twice the air velocity at a lower decibel rating, but with the same horsepower of competing models, the company claims. The unit’s electric heating or hot water/steam coil option functions as a space heater in the Comfort Plus mode to maintain vestibule set point temperature when doors are closed. The unit has a design that allows quick removal of modular blowers/motor, electric heating elements, and other components for easy maintenance and replacement. According to the manufacturer, the In-Ceiling Mount is an aesthetic ceiling flush-mounted solution to energy-saving environmental separation for 8- to 10-foot-high, 3- to 12-foot-wide pedestrian entrances in buildings where the inconspicuousness of mechanical support equipment is critical to interior design aesthetics.
