are industrial-grade central chilled water systems designed for marine, commercial, offshore, and drydock applications where raw seawater cooling is impractical, undesirable, or unavailable.
Eliminates raw water pumps, strainers, sea cocks, and marine growth fouling by discharging heat directly into ambient air.
Allows full vessel HVAC operation while hauled out of water for maintenance or operating in shallow/silty waterways.
Built on a heavy-duty marine-grade stainless steel chassis with weather-coated condenser coils for harsh salt-air environments.

Design
Central air-cooled marine chilled water plant built on a rigid 316 stainless steel chassis, incorporating high-static air condenser fans, isolated scroll compressors, and an NEMA electro-mechanical control enclosure.
Application
-
Commercial Workboats & Barges: Central vessel cooling without seawater intake clogging in muddy or shallow waters.
-
Drydock Maintenance & Shipyards: Continuous climate control for crew quarters while ships are out of the water.
-
Houseboats & Dockside Installations: Maintenance-free cooling for vessels moored in marinas with high silt, weeds, or marine growth.
