Work boat air conditioner OA-GZ Series

for offshore platformsfor passenger shipsreversible

Overview

The OA-GZ series is a floor-standing cabinet air conditioning unit designed for commercial vessels (passenger ships, workboats, offshore platforms). The compact cabinet integrates cooling, dehumidification, heating and ventilation functions. The unit can use river, estuary or seawater as the cooling source and features a side fresh-air inlet and direct grille discharge; digital controls simplify onboard operation.
