06 · Semi-industrial column systems for halls and lobbies.

Column air conditioners

Column air conditioners are built for large open spaces — hotel lobbies, exhibition halls, retail atriums, and commercial floors with ceiling heights that wall units cannot serve effectively. Semi-industrial column blocks deliver powerful, even airflow across the full room height without the cost and bulk of full ductwork.

We calculate cooling capacity based on floor area, window glazing, solar exposure, and pedestrian traffic — the factors that matter in high-ceiling commercial spaces. The right column unit maintains comfort without short-cycling or excessive noise.

About the service

We supply and install column units from Daikin, Mitsubishi Electric, and LG — floor-standing or on low pedestals, distributing air vertically through adjustable louvers. This makes them ideal where ceiling space is limited or where the interior design calls for minimal visible HVAC hardware.

Installation includes concealed refrigerant routing where possible, properly sloped condensate drainage, and dedicated electrical circuits sized to code. We coordinate placement with your interior team so units complement the space rather than dominate it.

After installation we commission each unit, verify refrigerant charge, and tune airflow patterns for quiet operation during peak business hours. Aurum Prodest provides a 5-year workmanship warranty on all column AC installations.

Brands

Column units are about throw, hall noise, and peak load. Pros/cons of the classes we install most.
