are heavy-duty direct-expansion (DX) marine HVAC package systems designed for applications where raw seawater cooling is impractical, unavailable, or high-maintenance.
Eliminates seawater pumps, thru-hull fittings, and strainers, completely avoiding marine growth clogging and raw water pump failures.
Keeps crew quarters and wheelhouses fully cooled while hauled out on land, in shipyard drydocks, or operating in shallow, muddy waters.
Built with heavy-gauge 316 marine-grade stainless steel panels and exclusive rolled louvers engineered for low turbulence and maximum airflow.
