STM-W/O series of dual-purpose heaters are mainly used to heat up the mould and maintain its temperature, although they can be also used in other similar applications. High temperature water or oil return from the mould is cooled by indirect cooling and then sent to the pipe heaters via high - pressure pump for heating to a constant temperature. This unique design allows user to choose between water and oil as heat transfer medium. With our optimized design, the HANYOUNG temperature controller can maintain an accuracy of ±0.5℃.

Features

  • Adopt water or oil as heating medium, the maximum tempera- ture can reach: water 95°C/203°F and oil is 160°C/320°F.
  • Controller adopts 3.2" LCD for easy operation.
  • 7-day automatic start/stop timer supports the conversion between Chinese and English, and °C and °F
  • P.I.D. multi-stage temperature control system can maintain a mould temperature with an accuracy of +0.5°C/0.9°F.
  • Adopt high efficiency, vertical dual-purpose of water/oil high pressure pump with stable performance and great pressure.
  • Multiple safety devices include power reverse phase protec- tion, pump overload protection, overheat protection and low level protection that can automatically detect abnormal perfor- mance and indicate this via visible alarm.
  • Equipped with pump reversion evacuation, automatic water supplying and negative pressure operation.
  • RS485 communication interface achieves centralized moni- toring with the host.
  • Standard equipped with the buzzer.

Working Principle

High temperature water returns to the machine and then be pressured by pump to the heaters. After being heated, water will be forced to mould and continue the circle. In the process, if the temperature is too high, the system will activate the solenoid valve to let cooling water lower the temperature directly till the water temperature is down to the system requirement. If the temperature keep rising and reach the set point of EGO, the system will alarm and stop operation. The system will have low pressure alarm and stop working if cooling water pressure doesn‘t reach the set point.

 

Application

STM-W/O series dual-purpose heaters are used to heat up the mould and maintain temperature, and also they can be used in other similar applications. This series of machines can use oil

or water as heat transfer media according to different production processes, as to adapt to different production conditions. Besides, this series of models have multiple options and

accessories to meet different production demands.
