In the manufacturing and processing processes in the steel, petrochemical, and food processing industries, there are many processes that need to maintain a constant temperature. Such processes are called industrial processes, and products of Ebara Refrigeration Equipment and Systems Co. LTD., is widely used as a heat source for industrial processes. We have developed chillers suitable for these conditions in a wide range of temperatures, from a relatively high temperature of about 10°C to an ultra-low temperature of -80°C.
