STM-W / STM-PW / Water Heater

Features：

• P.I.D. Multi-stage temperature control system can maintain a mould temperature with accuracy of ±1℃.
• Adopt high efficiency high temperature pump with great pressure and stable performance.
• Multiple safety devices can automatically detect abnormal performance and indicate via visible alarm.
• Compact design, easy to operate and maintain.

• Inner parts made from stainless steel to ensure explosion-free operation.
• For standard STM-W, the heating temperature can reach 120℃, while for STM-PW, it can reach160℃.
• STM-PW adopts indirect cooling method to maintain accurate temperature and quick heat transfer by means of steady cooling water flow.
• Pump reverse running for water drainage is an optional function for STM-W.
• Water manifolds and Teflon hose are optional.
• Upon request, it can be built to comply with worldwide electrical safety standards (CE, UL, CSA, JIS etc.).

Key Improvement：

Over-temperature alarm with self-locking function, which needs to reset manually in order to put into operation again. This function can protect machines on the spot when the temperature of heating barrel exceed the EGO set value and the alarm occurs, then the circuit breaker disconnect the power to stop heating. If the user is temporarily absent for some time, the temperature of heating barrel may be lower than setting value of EGO, alarm has automatically eliminated when the power was cut off to stop heating, the machine can not operate under the setting value, resulting in poor products and losses for customer. After installing self-locking function, when the temperature of heating barrel arrives at the level of the setting EGO temperature, temperature alarm will be worked constantly until trouble is worked out, and manual reset restart the machine to avoid potential loss.
