Colt’s Coltlite, a natural-louvered ventilator, provides buildings with day-to-day ventilation and smoke control to aid building evacuation in the event of a fire. The ventilator is available in double-pane louvers, single-pane louvers and aluminum louvers that can be specified with a powder-coat finish. Double-pane louvers are also available in a thermally broken design to minimize heat loss for reduced carbon emissions into the environment and maximize energy efficiency. The Coltlite control options allow building design professionals to integrate natural ventilation into an automated climate control system. In addition to the standard manual operation, products can be specified for electric or pneumatic operation, and set to open and close as required for proper ventilation.
