Winnex Air Marine Packaged Rooftop Air Conditioner

Winnex Air marine packaged rooftop air conditioner is an all-in-one integrated refrigeration system with all components assembled within one unit. It serves as an ideal climate control solution for ship wheelhouses, workshops and multiple commercial marine applications. The explosion-proof variant is specially suitable for marine electrical rooms. Featuring simple structure, high reliability, quiet operation and cost-effective performance, custom explosion-proof units are available upon request.

Equipped with two or more independent refrigerant circuits, the unit completes internal wiring and full pre-commissioning test before delivery for easy on-site installation. Designed for outdoor installation, the unit is fully engineered to withstand severe marine corrosive environment and wind-wave impact, delivering versatile marine cooling solutions. Central air supply and multiple structural options make it the optimal selection for vessel decks and offshore platforms.

Features

• Rigid structural design with special corner and central pressed steel frame. Pre-coated exterior panels, welded galvanized steel casing with baked finish; SS316 stainless steel construction and coating are optional. Internal protection panels adopt galvanized steel, polyester coated galvanized steel or stainless steel to resist long-term marine corrosion. 50mm thermal insulation layer is applied. Special panel and frame details prevent condensate forming on panels.

• Belt-driven high-efficiency low-noise centrifugal fans mounted on low-transmission isolators. The combination of centrifugal fan motor and pulley adapts to diverse working conditions. Fans for explosion-proof version are spark-resistant and can be disassembled from the side.

• Compressor options include Bitzer screw compressors or Danfoss / Copeland scroll compressors with built-in overload protection. Screw compressors are fitted with spring vibration isolators, automatic reversible oil pumps and unloading devices for outstanding part-load performance.

• Axial condenser fans with direct-drive enclosed motors and permanently lubricated bearings. Explosion-proof models comply with ATEX or IECEx requirements.

• Condenser and evaporator coils adopt copper tube with copper fins or hydrophilic aluminium fins, mechanically bonded plate fins and separate refrigeration circuits. Electrophoretic anti-corrosion paint or Blygold coating can be selected for enhanced protection. Integrated marine-grade stainless steel double drain pan is equipped with plastic or stainless steel water eliminators behind cooling coils for easy removal.

• Innovative non-corrosive composite condensate drain pan made of SS316L, available with side drain or central drain configuration.

• Standard refrigeration components include thermostatic expansion valve, oil level sight glass, filter drier and liquid line solenoid valve. Compressor suction service valves and liquid shut-off valves are fitted for convenient maintenance.

• High and low pressure safety switches (transmitters optional), plus low suction and overheat protection.

• Corrosion-resistant filter frame, standard material SS316L or GI, with easily removable filter elements.

• Control terminal board provides intelligent safety protection, simplified troubleshooting of safety circuits and compact control cabinet layout.

• User-friendly maintenance design with multiple inspection accesses and large transparent service doors for easy inspection.
