Applications

Commercial and industrial air handling units like these are the central air distribution components of large-scale HVAC systems. They draw in outdoor or return air, condition it through heating or cooling coils (in this case chilled water coils connected to a central chiller plant), and distribute the treated air throughout a building via ductwork. Units of this type and scale are standard in large commercial buildings, office campuses, hospitals, universities, manufacturing facilities, and data centers. Rooftop AHUs are especially common in commercial construction in the western U.S. due to space efficiency and simplified service access. Chilled-water systems of this type were widely deployed from the 1980s onward and remain the dominant approach for large commercial HVAC installations today. These units are well-suited for facility managers, mechanical contractors, or HVAC equipment resellers looking for large-capacity commercial handlers.
