Clion Marine offers a range of climate systems designed to support a healthy and comfortable indoor environment. Our Fresh Air units provide optimal temperature and air control on board. Clion Marine Fresh Air units can be connected to the chiller system and come equipped with humidity control and electric heating. Fresh outside air is heated and/or cooled to the desired temperature, while excess moisture is removed. Only once the target values are reached is the conditioned air distributed to various onboard areas. Long lifespan Fresh Air units are built with a robust design and high-quality materials. Each unit features a full stainless steel housing, and all components are protected against corrosion with a special coating. The units are highly resistant to the harsh marine environment and salty sea air. Custom engineering Clion Marine specializes in custom-engineered Fresh Air systems—available as standalone units or as an integrated part of the onboard climate system. We also offer technical support, including Fresh Air calculations and installation services.
