What is?

The Return Air Marine Air Conditioner is a return air conditioning unit specifically designed for ships. It draws in cabin air through return air ducts, filters, cools or heats it, and then returns it to the cabin, forming a complete air circulation.

Compared to 100% fresh air systems, the return air design significantly reduces energy consumption and is suitable for cabins such as crew living quarters, bridge, and control rooms. It features marine-grade corrosion resistance, vibration and roll resistance, and can withstand harsh conditions such as high salt spray, hull vibration, and trim/heeling.

With over 20 years of experience in the industry's refrigeration technology, Hisurp products have become the trusted choice of many ship owners worldwide due to their high efficiency, energy saving, stability, reliability, and flexible installation.

Feature

Seawater Cooling

Unlike conventional air conditioners that use air-cooled condensers, marine air conditioners utilize circulating seawater for heat exchange. This design results in higher cooling efficiency at high temperatures.

Effective Dehumidification

Given the extremely high humidity at sea, these units can quickly remove moisture while cooling the air, improving cabin comfort and reducing mold growth.

Adjustable Return Air Grille

The unit typically features a dedicated return air panel that draws air directly from the cabin. This panel includes a removable, washable air filter for easy maintenance.

Corrosion Resistance

Due to direct contact with seawater and marine salt spray, the condenser is usually made of copper-nickel alloy or titanium alloy, with a specially treated casing to withstand the harsh marine environment.

Low Noise and Compact Design

Designed with the unit installed near living areas (e.g., under the bed), it typically includes sound insulation and vibration dampers for low-noise operation.

Automatic Controls

Equipped with an intelligent thermostat that automatically switches between cooling, heating (if a heat pump function is available), and dehumidification modes.
