Passive airflow through a louvered panel is a common way to maintain adequate airflow to an engine room or machinery space. But there are times, such as during heavy weather or a fire event, when restricting ventilation is required. The new Louvered Closure from Delta "T" Systems has the outward appearance of a traditional vent, but features an integrated, vertically oriented aluminum damper hidden within.

Available in unlimited custom sizes, the Louvered Closure is ideal for any size vessel, from small yachts to large ships. It's made in the USA from fully welded marine grade aluminum with a wide flange for easy installation and a clean appearance. The heavy-duty louver blades have rounded leading and trailing edges. It's available powder coated to any color, or with a paintable mill finish.

The Louvered Closure features an ultra-reliable Belimo electric actuator that operates on 24–240 VAC or 24–125 VDC. It has absolute failsafe operation that uses power to open and spring-activated closing—guaranteed in the event of a power loss.

Delta "T" Systems manufactures a full line of quality fire dampers, axial and duct fans, blowers, louvers, moisture eliminators, weather closures and controls. Its complete engineered marine ventilation systems are installed on recreational, commercial and naval vessels worldwide.
