Space inside ship cabins is extremely valuable. Floor-standing and vertical cabinet air conditioners occupy walkways, storage and equipment layout areas, leading to insufficient installation space during renovation of narrow upper cabins, wheelhouses and deck lounges. To solve this industry pain point, Winnex Air launches the Marine Rooftop Packaged Air Conditioning Unit after years of R&D and manufacturing experience in marine temperature control equipment.

Adopting an integrated top hoisting structure, the complete unit is installed above cabin ceilings or decks without occupying interior floor space. It perfectly fits new ship construction, vessel retrofitting and offshore platform deck supporting projects, serving as a high-end space-saving climate control solution for marine scenarios.

Core Structural Design

The whole machine is an integrated fully enclosed sheet metal cabinet, with refrigeration, heat exchange, air supply, filtration, heating and electric control systems all integrated inside one unit, eliminating on-site segmented assembly. The hoisting base comes with built-in shock absorption structure, which can be directly fixed on cabin ceilings or rain-proof deck bases. Air ducts and refrigerant pipelines are pre-reserved at the bottom of the unit, and installation is completed by connecting downward to cabin air ducts for efficient construction.

All units comply with marine classification society standards for anti-corrosion, shock resistance and tilt operation. Outdoor versions are equipped with fully sealed rainproof casings to resist rain, salt fog and sea wind, suitable for both indoor cabins and semi-open deck areas.

Six Core Product Advantages

● Top-mounted Layout, Zero Occupation of Cabin Floor Space

Different from traditional floor marine air conditioners, the unit is fully hoisted on the top of cabins, completely freeing interior space for passage, equipment placement and storage. It is especially suitable for wheelhouses, viewing lounges, single crew cabins and offshore platform operation rooms with limited area, greatly improving cabin space utilization efficiency.

● Pre-assembled Integrated Unit to Shorten Shipyard Construction Cycle

All equipment completes refrigerant charging, pressure testing and continuous operation inspection before delivery. The integrated modular structure requires no on-site assembly. After hoisting fixation and connecting air ducts & pipelines, commissioning can be carried out immediately, reducing hull cutting, internal reinforcement procedures and cutting labor & steel modification costs for shipyards.

● Full Marine-Grade Anti-Corrosion & Shock Resistance for Severe Ocean Conditions

The whole cabinet adopts thickened marine anti-corrosion coating, and heat exchange components are made of salt-fog resistant Cu-Ni alloy. Equipped with heavy-duty composite shock absorption base, it ensures stable operation under ±30° long-term hull trim and heel. Outdoor models feature waterproof sealing structure to withstand heavy rain, high humidity and intense salt fog at sea, stable for coastal and ocean-going vessels.

● Integrated Multi-Functional Modules for Year-Round Constant Temperature & Humidity Control

The unit is equipped with multi-stage salt dust air filters, cooling & dehumidification coils, electric heating sections and silent air supply fans, with composite silencing cotton inside air ducts. It realizes cooling & dehumidification in summer, electric heating in winter and independent ventilation in spring & autumn. One single unit meets all-year demands of cabin temperature, humidity and air cleanliness, with operating noise far below marine specification limits.

● Premium Brand Core Components & Intelligent Control for Easy Maintenance

Fitted with world-famous brand marine compressors, the unit runs smoothly with low energy consumption and long service life. Key electrical components including pressure controllers, temperature modules and circuit breakers all adopt first-class industrial brands to lower failure rate. Full-opening maintenance panels are reserved on the top and side of the unit, allowing filter, compressor and electric component inspection & replacement without dismantling the hoisting base, simplifying onboard maintenance.

● Full Compliance with Marine Standards & Customization Support

The design, production and inspection of the unit strictly follow CCS rules, SOLAS international marine conventions and naval vessel standards. The electrical system meets marine EMC requirements; ATEX explosion-proof versions are optional for chemical tankers and FPSOs. Customization on air volume, cooling capacity, overall dimension and explosion grade is available to match differentiated marine project demands.

Typical Application Scenarios

Container ships, bulk carriers, yachts & passenger vessels, official law enforcement ships, research vessels, offshore wind service ships, offshore oil drilling & production platforms. Widely applied to wheelhouses, single crew cabins, deck lounges, platform control rooms, viewing leisure cabins and small instrument equipment rooms requiring top-mounted installation.
