Our company is the only enterprise in the northeastern region that produces air coolers, and we undertake ventilation projects (equipped with duct production lines, large-scale equipment including three lines, plasma cutters, seam welders, and corner presses). We are a comprehensive business that integrates production, sales, and after-sales services. Our independently developed and produced "Shengfeng" energy-saving and environmentally friendly air conditioner is a new product that is highly efficient, energy-saving, and eco-friendly. The principle of cooling through water evaporation is widely applied in our daily lives; for instance, when we stand by the seaside, we feel particularly cool, or when there is moisture on our skin, a breeze can make us feel much cooler. This is because during the process of evaporation, water absorbs heat from the air, thus lowering the air temperature. The "Shengfeng" energy-saving and environmentally friendly air conditioner utilizes this natural phenomenon, combining high technology with direct evaporative cooling technology to develop a new generation of air coolers that integrate cooling, ventilation, humidification, odor removal, and energy conservation. The core component of the "Shengfeng" energy-saving and environmentally friendly air conditioner - the direct evaporative heat exchanger, known as the "multi-layer corrugated fiber composite" wet curtain, is a patented product from Sweden. Its features include excellent water absorption, ventilation, and filtration capabilities, with an actual heat exchange area nearly 100 times its surface area. It is robust, resistant to water immersion, corrosion, and deformation, with a normal service life exceeding 6 years. It can achieve a cooling effect 5-15°C lower than the outside temperature. Suitable for open or semi-open spaces, it ventilates and cools, expelling unpleasant, hot, and stuffy, turbid gases from indoors to outdoors under positive pressure, while increasing oxygen levels, creating a comfortable and pleasant working environment for you. With low operating costs, it consumes approximately 1 kWh per hour at most, saving over 80% more electricity compared to traditional air conditioners, and is green and environmentally friendly, containing no chlorofluorocarbons. The Shengfeng brand air cooler is your best choice.
