  • Page 7: General Description

    General Description Read this manual carefully before operation to prevent damage of the machine or personal injuries. STM-E (WE) series are applicable for heating up the moulds and maintaining temperature, and they also can be used in other similar applications. Firstly, these series adopt different cooling methods to cool down mediums, then mediums are conveyed to the moulds after pressurized by pump and heated up by electrical heated tube.

  • Page 8: Coding Principle

    1.1 Coding Principle 1.2 Feature 1) Standard configuration ● P.I.D. multi-stage temperature control system can maintain a mould temperature with accuracy of ±1℃. ● Adopts high efficiency high temperature pump to achieve high efficient heat exchange. ● Multiple safety devices including power reverse phase protection, pump overload protection, overheat protection and low level protection that can automatically detect abnormal performance and indicate this via visible alarm.
