The Polar Air Double Skin Ducted Fan Coil Units are designed for high capacity cooling applications where enhanced insulation is beneficial, particularly in tropical climates. The double skin casing provides a thermal barrier that helps maintain conditioned air temperature, improving system efficiency in both cooling and heating modes.

This series offers a cost effective solution suitable for both commercial and residential environments, delivering a comfortable indoor climate. Its compact dimensions, low profile design, and quiet operation make it ideal for installations with limited ceiling space.

Standard Configuration

The ducted high series are supplied with return plenum, 7mm air filter with aluminium frame, interchangeable left/right side coil connections and dynamically balanced centrifugal fans.
