Product Features and Options The is a self contained air conditioning system designed specifically for spot cooling applications. The is mounted above the ceiling with integral supply and return grill that fits a standard 2' x 4' ceiling grid. There are five cooling capacities ranging in size from one to three tons making it ideal for supplementary cooling of existing space or new construction. The standard air-cooled unit comes with a belt-driven condenser fan that has field adjustable external static pressure ranging from.1 to 1.0" to allow for various sizes and lengths of ductwork. A remote air-cooled condenser is also available for exterior installation. Other cooling options include water/glycol cooled and chilled water units.
