Compressed Air Used in Marine

Air compressors are used in the ship for a number of purposes, including blowing off the sea valve, cleaning the oil residue cabinet, using compressed air as whistles, launching torpedoes, and refueling submarines.In addition, Marine space is limited and seawater is corrosive, so it is extremely important to select compressed air purification products that are suitable for the marine environment. YunAir's high-efficiency HG series air filters have a parallel installation design that is not only space-saving, it has strengthened corrosion protection and is suitable for use in marine environments.

Staring Air

Large diesel engines are launched with the assistance of compressed air on ocean ships as a powerful and stored energy source. Although the air is used under a lower pressure of 150 psi, it is usually stored with a higher pressure to optimize its use, and at the same time, a sufficient volume of air is still allowed to be used for multiple starts.

Control, Instrumentation and Work Gas

There are numerous systems and processes on the boat that require the compressed air, such as engine emissions monitoring system, throttle control, control valve, etc.

Lubricating Air for Hull

When the ship is pushing water, it will encounter resistance. By designing a special hull, low -pressure air can be blown through small holes to generate a layer of air between the hull and water. The air layer improves the consumption efficiency of potential fuel by more than 25%, and reduces the resistance of the ship when the carbon dioxide emissions are reduced.

Inert Gas Nitrogen

A ship that transports LNG (liquefied natural gas) or uses LNG as a fuel must cover its fuel tanks with nitrogen to prevent explosions. At the site, nitrogen and oxygen can be separated from compressed air, which is more convenient and economical than transporting nitrogen tanks. Thus, it is extremely important to select reliable air compressors, air dryers, and air filters to have pure nitrogen.
