Dehumidifiers for Cargo and Ship Holds

The relative humidity in a ship is very high for the obvious reason that they mainly operate in the sea or ocean. The humidity can reach an extreme level of as much as 95 percent because of the continuous evaporation taking around the environment. A cargo ship might have to carry varieties of products some of which are highly hygroscopic in nature. Some of the examples include paper,  fertilizers, various food items such as corn, electronic parts, textiles, and many more. These products when exposed to high humidity for a long period of time can get damaged leaving them unusable. Of course, the first priority of cargo ships is to deliver the products unscathed. Delivering damaged products can really hamper the overall image of the company. That is why humidity reduction should be very much prioritized in the ships before, during, and after the transportation.

The best remedy for mold development, corrosion, and other microbial contamination is the continuous supply of moisture-free air i.e. dries the air. It is very important to maintain the humidity of the air at the right level to protect the goods on the ship. The only way to achieve humidity levels with such precision is possible only by the use of dehumidifiers. 

What is the Right Level of Humidity inside the Ship?

Many of our customers ask us about the level of humidity to be maintained inside a cargo ship? But to be absolutely honest there is no fixed answer. The humidity level maintained depends upon the kind of goods that are being carried. Hence one has to keep the goods being carried into consideration before determining the most appropriate humidity level. For example, if a cargo ship is carrying stuff such as batteries of lithium then the humidity levels should be maintained no more than 2 percent while for other pharmaceutical goods the humidity level should be maintained at about 10 percent. Similarly, corn should be stored at about 65 percent humidity while printing products and paper the proper amount of humidity is around 40 to 55 percent. But it is better not to have humidity more than 50 percent to avoid any kind of bacterial development. Our data loggers which are tamper-proof will also assist you to keep track of the climatic conditions in the ship.

Our Dehumidifiers with Silica Gel Rotors 

Our dehumidifiers come with silica gel rotors which provide stability for offshore application. They are specially designed to operate in offshore conditions. They are also perfect for drying the whole ship after cleaning with water or sandblasting in the shipyard. These dehumidifiers have a system that separates the supplying air process and regeneration of the air process and ensures great economic efficiency. All of our dehumidifiers come with silica gel sorption rotors which are highly stable in nature. These dehumidifiers can operate in a wide range of temperatures which is as low as -15 degrees Celsius and as high as +35 degrees Celsius. With a wide range of models with different performance classes and sizes to choose from we are sure to meet the requirement of our customers. 

Corrosion Resistant Dehumidifiers made of Stainless Steel

Sometimes the cargo ships have to be on the go for a long period of time. In such stances dehumidifiers that are corrosion resistant made of stainless steel is the right choice to go. These dehumidifiers possess a standard radial fan along with an extra-powerful fan motor that helps them to operate them with high compression. Other additional features of the dehumidifiers are integrated heat recovery, self-regulating PTC heating, and operating hour counter.

Ambale Dehumidifier units are supplied in Fiji, Tauranga, Hamilton, Bay of Plenty Region, Auckland, Wellington, Northland, and various parts of NZ and Fiji. Please send us an email with your query to or call us on +64 22 061 7007 and talk to our engineer.
