Rooftop Package Units

Packaged rooftop plant on a galvanised steel base, built for high ambient operation.

Where there is roof to use and no room for an indoor plant space, the RUA packaged unit puts the whole system in one weatherproof casing — scroll compressor, both coils, both fans, and a control board that tells a service engineer what went wrong.
