Nanometer technologyActive metal substances for air purification purposes are arranged in nanometer precision to enable effective elimination of methylene oxide, benzene, triclene and some other gases that might cause cancer, with an elimination rate as high as 99.09%. Active biologic enzyme technologyThis technology, introduced from the USA, is transplanted to the air filter system to effectively kill the Grands positive bacteria, Grands negative bacteria, funguses, saccharomycetes and viruses, with an elimination rate as high as 99.99%. Other health-caring technologiesThe health-caring negative ion can effectively increase the oxygen inside the room and keep the room air fresh ; the optic catalyst and cold catalyst can remove dust and kill germs so that an all-round healthy envirornment is achieved. Digital dynamic central display screenThe high-resolution display screen displays the operational statuses of the air conditioners in an appealing and easy-to-operate way with all the controls available. It features the high-class style of modern life. Multi-bending evaporatorThe evaporators are in the multi-bending designing, which greatly increases the heat exchange spaces, accelerate the cooling speed and save more energy. Environment-friendly refrigerants (optional)The Green Pioneer series products adopt the environment-friendly R407 refrigerant, which makes possible the genuinely environment-friendly air conditioners with freon to do harm to the atmosphere. Intelligent controlsMultiple intelligent technologies asre applied, such as the automatic control for sleeping mode, economic operational mode, faulty automatic diagnosis, automatic defrosting, etc. to bring about perfect convenience and comforts to the end-users to demonstrate the the utterly humanized designing of Chigo.
