The MARS Star II Series Flooded Screw Water-cooled Chiller comes with a heritage of the spectacular design of European screw chillers and brings together the scientific and technological achievements of EK for designing and manufacturing chiller systems for more than half a century. It uses EK efficient semi-hermetic low-noise single-screw compressors, R134a environment-friendly refrigerant, and efficient flooded evaporator, and adopts the cutting-edge AI microcomputer control technology of EK to achieve efficient operation, system reliability, and low noise. All these make EK central air conditioners the preferred choice for the central air-conditioning systems for high-end hotels, office buildings, schools, hospitals, factories, enterprises, and other large- and medium-sized public buildings and civil buildings.
