ETI-Z centrifugal chillers, which use low-environmental-impact refrigerant HFO-1233zd(E), have been widely used since their launch not only for industrial applications but also for general air conditioning applications such as building air conditioning, and are the most widely employed centrifugal chillers in Japan. Recent growing environmental awareness following the Paris Agreement requires equipment to have a low environmental impact and be energy-efficient. At the same time, the emergence of the AI industry has led to the expansion of data centers and demand for semiconductors, while the need for air conditioning and refrigeration continues to grow along with industrial development. Against this background, centrifugal chillers of Mitsubishi Heavy Industries Thermal Systems, Ltd., which have been providing air conditioning and refrigeration solutions over the years, are now required to be even more energy-efficient. Therefore, we have developed high-performance models in the ETI-Z series, which have been based on the concept of high performance and miniaturization, with even higher energy efficiency while retaining the miniaturization advantage over competitors in the market, achieving a significant improvement in performance compared to conventional models.
