PCU-NE Series non-freon chillers use R1234yf refrigerant. Because the PCU-NE Series chillers uses non-freon refrigerant they are exempt from the Fluorocarbons Recovery and Destruction Law and have absolutely no fluorocarbon-related labor and costs such as periodic inspections and preparing process management documentation required of fluorocarbon chillers. What’s more, they are the first chillers in the industry market with drive recorder and time calendar functions. The chiller records circulation water outlet temperature, circulation water set temperature, accumulated operating time, error date and time, and other important operation data in two minute intervals. By monitoring chiller operation status and isolating the cause of problems, these functions greatly reduce the time and effort consumed on dealing with problems just in case one occurs.
