The water type mold temperature controller series includes standard type, high temperature type and dual temperature type, mainly used to control mold temperature and keep the mold at a constant temperature. Using water as heat transfer medium, heat exchange is achieved through direct or indirect cooling. The standard type mold temperature controller adopts direct cooling through the cooler with mold return water/high temperature type adopts indirect cooling through the cooler, pressurized by the pump and heated through the electric heating tube before being sent to the mold, to meet the requirements of heating and constant temperature. It has the advantages of high heat transfer efficiency, less pollution, easy access to water resources and low usage cost.
