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.
