■ Features
• Large water flow design with a maximum working tem¬perature of 120°C.
• In build weekly timer with °C°F unit conversion.
• P.LD. multi-stage temperature control system can main¬tain a mould temperature with an accuracy of ±0.5°C.
• In build multiple safety with display and alarm buzzer, such as reverse phase, pump overload, overheat, and low water pressure.
• Direct cooling with excellent heating exchange. Auto refilling device cools down the temperature to set value directly.
• Modbus RTU data communication via RS485.
■ Options
• Displays of mould temperature and return water tem¬perature of mould are optional, and add "TS" at end of the model code.

STM-WF series "Large Flow" water heaters are used to heat up the mould and maintain temperature, and also they can be used in other similar applications. Compared with standard water heaters STM-W, this series of machines adopt large flow pump that are especially applicable to large flow and constant temperature productions, such as plates and extrusion molding etc. Besides, this series of models have multiple options and accessories to meet different production demands.

Working Principle
Reference formula of Mould Controllers model selection
Heater Power (kW) = mould weight (kg) x mould specific heat (kcal/kg'O) x temperature difference between mould and environment (C) x safety coefficient / heating duration / 860
Notes: safety coefficient range 1.3-1.5.
Flow Rate (L/min) = heater power (kw) x 860 / [heating medium specific (kcal/kg'O) x heating medium density (kg/L) x in/outlet temperature difference CO) x time (60)]
Notes: Water specific heat = lkcal/kgt: Heating medium oil specific heat =0.49kcal/kgiC Water density =lkg/L Heating medium oil density =0.842kg/L
Time for heating=the time needed to heat from room temperature to set temperature
