The high-performance chiller PCU-SL Series’ innovative IOF sensor constantly monitors circulation water inlet and outlet temperature and circulation water flow rate. By making it possible for the chiller to detect changes in load and flow faster and more accurately caused by production processes than any other chiller, the sensor quickly stabilizes circulation water temperature. What’s more, PCU-SL Series chillers have an innovative structure that gives them the toughness needed for harsh environments. Additionally, a structure that separates the top and bottom of the unit provides IPX4 water protection that withstands tests even more demanding than JIS standards, thus making it possible to install the chiller outdoors with confidence.
